*Income from continuing operations, including charges and credits, was $2.072 billion in 2015 and $5.643 billion in 2014. Diluted EPS from continuing operations, including charges and credits, was $1.63 in 2015 and $4.31 in 2014. See section entitled "Charges & Credits" for details.

Schlumberger Chairman and CEO Paal Kibsgaard commented, "Full-year 2015 revenue of $35.5 billion decreased 27% year-on-year in line with upstream capex spending cuts that resulted in significantly lower E&P investment levels. North America revenue declined 39%, with land falling 45% while offshore was down 17%. The decrease in land activity was the sharpest seen since 1986, as capex spending by North American customers declined by more than 40%. With the year-end US land rig count 68% lower than the 2014 peak, at less than 700 rigs, the massive over-capacity in the land services market offers no signs of pricing recovery in the short to medium term.

"Full-year revenue for the International Areas declined 21% due to customer budget cuts of more than 20%, as international and national oil companies responded to lower commodity prices. This effect was exacerbated by service company pricing concessions. More than one-third of the revenue decline was the result of the fall of certain currencies against the US dollar. Performance among the Areas was led by a 26% decrease in Europe/CIS & Africa, mainly due to weakness in the Russian ruble. Exploration activities in the UK and Norway fell as customer spending decelerated. In Sub-Saharan Africa, offshore rigs demobilized as exploration work decreased, and in North Africa work progressed slowly, partly because activity in Libya remained muted as onshore operations were limited by security concerns. Full-year revenue in the Latin America Area declined 22% due to significantly decreased activity in Mexico, Brazil and Colombia as a result of sustained budget cuts that led to rig count reductions. Devaluation of the Venezuela bolivar impacted revenue in the Venezuela, Trinidad & Tobago GeoMarket. Middle East & Asia Area full-year revenue decreased 17% due to a significant activity drop in the Asia-Pacific region, particularly in Australia. This decrease was partially offset, however, by robust activity in the Gulf Cooperation Council countries in the Middle East, particularly Saudi Arabia, Kuwait and Oman, although the effect of this was offset by pricing concessions. Activity in Iraq continued to decline.

"Full-year Schlumberger pretax operating income declined 38%, with pretax operating margin contracting 342 basis points to 18.4%. North America margin declined 874 basis points to 10.2% on decreased pressure pumping activity and pricing weakness on land. International margin was essentially flat with 2014 at 23.6% despite the revenue decline from pricing concessions, and from an increasingly unfavorable shift in revenue mix from offshore exploration to development. While revenues in North America and in the International Areas have declined by 39% and 21%, respectively, decremental operating margins have been limited to 32% in North America, and 25% internationally. These figures are substantially better than those we delivered in the 2009 downturn.

"The strength of these results demonstrates the resiliency of our business portfolio in the face of the activity, pricing and foreign currency challenges of 2015. Our performance was driven by excellence in execution, prompt and proactive cost and resource management, and the growing impact of our transformation program.

*Loss from continuing operations, including charges and credits, was $1.016 billion in the fourth quarter of 2015. Income from continuing operations, including charges and credits, was $302 million in the fourth quarter of 2014. Loss per share from continuing operations, including charges and credits, was $0.81 in the fourth quarter of 2015. Diluted EPS from continuing operations, including charges and credits, was $0.23 in the fourth quarter of 2014. There were no charges or credits recorded during the third quarter of 2015. See section entitled "Charges & Credits" for details.

"Fourth-quarter revenue decreased 9% sequentially driven by the continuing decline in rig activity and persistent pricing pressure throughout our global operations that also suffered from activity disruptions and project delays and cancellations. North America revenue fell 14% sequentially as the US land rig count declined 15% and customer E&P budgets were exhausted. International revenue declined 6% due to the combination of customer budget cuts, the start of the seasonal winter slow-down, persistent pricing pressure, and the largely muted year-end product, software, and multiclient seismic license sales.

"Among the business segments, Production Group revenue declined by 10% on lower pressure pumping services in North America. Reservoir Characterization and Drilling Group revenues declined sequentially by 7% and 8%, respectively, on lower demand for exploration-related products and services in the International Areas as customer budgets were exhausted. These effects were amplified by the almost complete absence of the year-end product, software, and multiclient seismic license sales that have typically offset seasonal winter slow-downs in previous years.

"Negative market sentiments intensified in the fourth quarter, with oil over-production continuing and extending the bearish trend in global inventories. This led to a further drop in oil prices, which reached a 12-year low in January 2016. The worsening market conditions added further pressure to a deepening financial crisis in the E&P industry, and prompted customers to make further cuts to already significantly lower E&P investment levels. Customer budgets were also exhausted early in the quarter, leading to unscheduled and abrupt activity cancellations.

"In anticipation of an extended activity weakness in the first half of 2016, we implemented another significant adjustment to our cost and resource base during the fourth quarter. This included a further workforce reduction of 10,000 employees, as well as greater streamlining of our overhead, infrastructure and asset base. This led us to recognize in the fourth quarter $530 million in pretax restructuring charges for expanding the incentivized leave of absence program and reducing our workforce, as well as a largely non-cash $1.6 billion pretax impairment charge for fixed assets, inventory write-downs, facility closures, contract terminations, and other asset impairments.

"In spite of the challenging business landscape, we generated approximately $5 billion in free cash flow in 2015, after taking into account capital expenditures of $2.4 billion and $1.4 billion of investments in future revenue streams. We returned $4.6 billion in cash to our shareholders, through $2.4 billion in dividend payments and $2.2 billion in stock buy-backs. We also spent approximately $500 million on technology acquisitions, while increasing our net debt by only $160 million. Our ability to generate cash in this environment has been unmatched in the oilfield services industry, and has given us an unrivaled ability to capitalize on a variety of significant business opportunities.

"As the pending Cameron transaction progresses, pre-close integration plans are substantially complete, and we will be ready to close once all regulatory approvals are received. We expect this to occur in the first quarter of 2016 and we have already received approvals from regulators in the US, Canada, Brazil and Russia. In addition, Cameron shareholders have voted to adopt the merger agreement and we have secured the necessary financing for our US subsidiary that will make the acquisition. The large stock component of the deal, with 78% in stock and 22% in cash, has largely insulated us from market volatility.

"In this uncertain environment, we continue to focus on what we can control. Throughout the year we took a number of actions to streamline and resize our organization as we continued to navigate the downturn. In continuing to accelerate the benefits of the transformation program across both our Technologies and GeoMarkets in 2016, we believe we will emerge as a stronger company relative to industry peers and competitors once the price of oil and the market conditions in our industry turnaround.

"We remain constructive in our view of the market outlook in the medium term, and continue to believe that the underlying balance of supply and demand will tighten, driven by growth in demand, weakening supply as E&P investment cuts take effect, and by the size of the annual supply replacement challenge."

Other Events

During the quarter, Schlumberger repurchased 5.4 million shares of its common stock at an average price of $73.86 per share for a total purchase price of $398 million.

On October 19, 2015, Schlumberger and Energy Recovery, Inc. signed a 15-year technology agreement to provide Schlumberger exclusive rights to Energy Recovery's VorTeq™ hydraulic pumping system.

On November 9, 2015, Schlumberger and Ikon Science announced an agreement to further develop the quantitative seismic interpretation capability in the Petrel* E&P software platform.

On November 16, 2015, Schlumberger announced the acquisition of Fluid Inclusion Technologies, Inc., a US-based oil and gas service company specializing in laboratory analysis of trapped fluids in rock material and advanced borehole gas analysis.

On November 17, 2015, Schlumberger received unconditional approval from the US Department of Justice regarding the proposed merger between a wholly owned subsidiary of Schlumberger Limited and Cameron International Corporation (Cameron). In December 2015, unconditional clearances were also received from anti-trust authorities in Brazil, Canada and Russia. Cameron shareholders overwhelmingly approved the merger agreement at a special meeting on December 17, 2015, and the closing of the proposed merger now remains subject to clearance by the European Commission and certain other jurisdictions, and the satisfaction or waiver of other customary closing conditions.

On December 10, 2015, Schlumberger Holdings Corporation, an indirect, wholly-owned U.S. subsidiary of Schlumberger Limited, issued five tranches of senior notes aggregating $6 billion. These notes have a weighted-average interest rate of approximately 3.15% and maturities ranging from 2017 to 2025. Net proceeds will be used for general corporate purposes, including financing part of the pending acquisition of Cameron.

On January 21, 2016, the Company's Board of Directors (the Board) approved the quarterly cash dividend of $0.50 per share of outstanding common stock, beginning with the dividend payable on April 8, 2016 to stockholders of record on February 17, 2016. Additionally, in view of the fact that the Company's current $10-billion share repurchase program that commenced in the third quarter of 2013 is about to be completed, the Board also approved a new share repurchase program of $10 billion.

North America

North America fourth-quarter revenue of $2.0 billion decreased 14% sequentially, largely mirroring the US land rig count decline of 15% as customer cash flows diminished and E&P budgets were exhausted. Land revenue fell 18% from lower activity and persistent pricing pressure, while offshore revenue decreased 4%. The usual year-end surge in multiclient seismic license sales was largely muted compared to previous years.

North America pretax operating margin declined 175 basis points (bps) sequentially to 7% as a result of pricing pressure that impacted all services and products. In the pressure pumping market in particular, unsustainable industry pricing levels led to more pumping equipment being stacked and crews released. In certain basins, however, hydraulic fracturing fleet deployment was maintained in pursuit of market share and new technology opportunities.

Despite revenue declining sequentially by 14%, the decremental operating margin was only 20%. The strength of this performance was underpinned by prompt cost and resource management, effective supply chain processes, and strong operations management.

In the fourth quarter, integrated services and new Schlumberger technologies helped increase production and operational efficiency in North America.

In US Land, Well Services BroadBand* unconventional reservoir completion services have been deployed in 14% more wells and in 52% more stages as compared to 2014. BroadBand technology maximizes wellbore coverage and reservoir contact to increase production and recovery by stimulating and propping open every fracture from tip to wellbore. The Eagle Ford and Permian Basins reflected the highest activity in 2015 while total activity covered six basins and 32 operators.

In South Texas, a combination of Schlumberger technologies enabled Lonestar Resources Ltd. to optimize production on a group of horizontal wells in the Eagle Ford shale play. Well Services Mangrove* reservoir-centric stimulation design software helped improve the hydraulic fracturing design by using geological property measurements acquired by Wireline ThruBit* logging services. As a result, 30-day production rates on the wells completed with the optimized fracturing design increased 78% compared to offset wells in the same field.

Also in US Land, the Drilling & Measurements PowerDrive Orbit vorteX* motorized rotary steerable system achieved repeated successes in the Midland and Anadarko Basins. In the Midland Basin's Wolfcamp formation, this technology established a record rate of penetration (ROP) by drilling an average of 245 ft per hour to a total depth of more than 7,100 ft in 29 on-bottom hours. In the same formation, the PowerDrive Orbit vorteX system drilled at an average ROP of 203 ft per hour to a total depth of 12,600 ft in a record-breaking time of four days. Drilling & Measurements also deployed PowerDrive vorteX technology for the first time in the Anadarko Basin's Woodford Shale to increase ROP by 120% compared to the area's previous well average, with the total vertical depth of one 14,960-ft lateral being the longest run of any size borehole in the South-Central Oklahoma Oil Province Woodford Shale.

Elsewhere in US Land, M-I SWACO deployed SCREEN PULSE* fluid and cuttings separator technology to enhance the performance of the solids control process, to maximize recovery of high-quality reusable drilling fluid, and to reduce the drill cuttings waste generated. Maintaining the drilling fluid in optimum condition enhances drilling efficiency and reduces the cost of waste handling and disposal, while improving safety performance at the wellsite. Since its launch in May 2015, SCREEN PULSE technology has proven its performance with fluid discard rates reduced by up to 50% and with oil-on-cuttings levels reduced by approximately 35% on operations in the Woodford, Eagle Ford, Haynesville and Permian shale basins.

In Atlantic Canada, Schlumberger completed the first year of an integrated services contract for Statoil, Inc. offshore Newfoundland. The exploration and appraisal of the Flemish Pass Basin used a combination of Schlumberger technologies that improved drilling efficiency, assured wellbore integrity, and optimized placement of a well in a water depth of 2,829 m. The PowerDrive Xceed* ruggedized rotary steerable system, Rhino XS* hydraulically expandable reamer, and Stinger* conical diamond element achieved stable and accurate drilling to target depth. Quanta Geo* photorealistic reservoir geology service, LithoScanner* high-definition spectroscopy service, and the Sonic Scanner* acoustic scanning platform characterized the complex formations and reduced subsurface risk. Deployed during a single descent, this combination of technologies saved the customer rig time and Statoil listed several hole sections among their top drilling performances worldwide.

In another project offshore Atlantic Canada, Wireline deployed a combination of technologies for Statoil, Inc. in the formation evaluation and reservoir characterization of the deepwater well Bay du Nord. Wireline technology included Rt Scanner* triaxial induction service, Quanta Geo photorealistic reservoir geology service, and the Sonic Scanner acoustic scanning platform in order to reduce subsurface risk and characterize the complex formations. As a result of the efficient wireline run, the customer saved rig time.

International Areas

Revenue for the International Areas of $5.7 billion decreased 6% sequentially due to the combination of customer budget cuts, the start of the seasonal winter slow-down, persistent pricing pressure, currency weakness and the largely muted year-end product, software, and multiclient seismic license sales.

Middle East & Asia Area revenue of $2.2 billion declined 5% sequentially mainly due to lower activity in Australia and the Asia-Pacific region as a result of customer budget cuts and project completions. Revenue from the Middle East GeoMarkets was also lower as solid activity in Kuwait and Iraq was more than offset by reductions in the rest of the region due to the effects of service pricing concessions, project cancellations, delayed start-ups of new projects, and abrupt activity disruptions as budgets were exhausted.

Europe/CIS/Africa Area revenue of $2.1 billion dropped 9% sequentially mainly in Russia and Central Asia due to weakness in the Russian ruble, the start of the seasonal winter slow-down in Russia as summer projects wound down, and activity reductions in the Caspian region. Solid activity in the Nigeria & Gulf of Guinea and North Africa GeoMarkets was offset largely by lower activity in the UK, Central & West Africa and Angola GeoMarkets as rig count declined and projects ended.

Revenue in the Latin America Area of $1.4 billion declined 1% sequentially, mainly on significantly lower activity in the Colombia & Peru, Brazil, and Argentina, Bolivia & Chile GeoMarkets due to customer budget cuts and currency weakness. These effects were largely offset by marine seismic acquisition surveys and multiclient seismic license sales in Mexico.

International Area pretax operating margin of 22% decreased 170 bps sequentially as pricing pressure across the Areas was partially offset by streamlining the cost and resource base and by acceleration of the transformation program. In addition, project cancellations, delayed start-ups of new projects, and abrupt activity disruptions all contributed to the sequential reduction in pretax operating margin, particularly in the Middle East & Asia Area. Middle East & Asia pretax operating margin decreased 448 bps to 22.5%, Europe/CIS/Africa fell 138 bps to 20.8%, while Latin America increased 229 bps to 23% mainly due to strong margins from multiclient seismic license sales in Mexico and Central America.

Sequential decremental operating margin reached 51% as abrupt operational disruptions impeded prompt cost adjustments, and pricing pressure accounted for more than a third of the revenue decline.

In the fourth quarter, the transformation program increased workforce productivity through a combination of multiskilling, optimized base support, and asset utilization. For example in the North Sea:

The creation of an Optimized Support Team in January 2014 meant that Wireline field experts required approximately 2,000 fewer days at the base in 2015 compared to the previous year. Field team members were thus able to focus more on their core activities at the wellsite and reduce the amount of time spent on non-core tasks at the base. This yielded an annual savings of $1 million while contributing to employees' work-life balance. In addition, Wireline increased asset utilization by 54% compared to 2014 by consolidating and sharing assets within a wider geographical region. In turn, the asset utilization improvement led to a reduction in materials and supplies in excess of $800,000.

A total of 19 M-I SWACO Drilling Solutions engineers were trained on how to perform key field operations, which included deployment of CLEANCUT* cuttings collection and containment systems and AUTOMATIC TANK CLEANING* units that can be operated by smaller number of crews. During the first four months after training, the multiskilled engineers delivered safe and high quality job performance, while the number of people on board was reduced by more than 350 man/days.

Wireline and Slickline crews cross-trained for operations on board Light Weight Intervention Vessels for three international oil companies. Through multiskilling initiatives, safety risks were reduced due to fewer people on board, and the three customers saved a combined total of 328 work days.

The fourth quarter also saw an expansion of integrated services in the International Areas as well as a number of new contract awards.

In South Korea, Integrated Services Management (ISM) completed a single-well, deepwater exploration project for Woodside. Mobilization was required over a very short timeframe and included complex logistics related to the licensing and importation of logging tools, and supplies for potential pipe recovery. Co-located in Woodside's Busan supply base, the ISM project manager worked alongside the Woodside logistics team to import the required materials and supplies from 14 different countries. As a result of the close collaboration between Schlumberger and Woodside, all material, personnel, and services were successfully delivered on time and the project was successfully executed as per the drilling plan.

Offshore Norway, Integrated Drilling Services (IDS) delivered superior drilling and completion performance for Det Norske Oljeselskap ASA on the Ivar Aasen Project. Schlumberger StingBlade* conical diamond element technology contributed to improved rate of penetration while Drilling & Measurements GeoSphere* reservoir mapping-while-drilling service was used to geologically steer three horizontal well sections up to 2,000 m in length. GeoSphere technology enabled the real-time delineation of layers in the reservoir at distances in excess of 30 m while steering the laterals to maximize reservoir contact. As a result of the close collaboration between the Det Norske and Schlumberger teams, the drilling and completion of all three wells ranks among the top 10 best performances in the last eight years on the Norwegian continental shelf.

In 2015, Integrated Production Services (IPS) supported three multiwell abandonment programs for an international oil and gas company by providing a range of project management, plug and abandonment engineering, and well services. The projects were both on land and offshore in Europe and Asia. Services from Bits & Drilling Tools, Wireline, Well Services, M-I SWACO, and Well Intervention were integrated using IPS engineering and project management processes to help reduce project cost, increase efficiency, and ensure compliance with both regulatory and customer requirements.

In Norway, OMV (Norge) AS awarded Schlumberger a three-year integrated services contract with two one-year extensions for the provision of exploration and appraisal drilling services on the Norwegian Continental Shelf. This included drilling fluids and waste handling, cementing, directional drilling, measurement-while-drilling, logging-while-drilling, mud logging, wireline logging, well testing, and project management services. The contract will provide proof of concept for drilling and geosteering in a very shallow reservoir to achieve high horizontal well productivity.

The UK Oil and Gas Authority has awarded Schlumberger two projects on the North Sea UK Continental Shelf (UKCS) and will offer the project deliverables free of charge to oil companies with an interest in the UKCS. This is part of the UK Government's goal to reinvigorate interest in exploration on the UKCS, particularly in under-explored areas. WesternGeco will conduct two 2D marine seismic surveys in the UK Rockall and Mid North Sea High and provide data processing services, petroleum systems modeling, and multiclient data. Software Integrated Solutions (SIS) will provide licenses for key software platforms, including Petrel* E&P software, Studio* E&P knowledge environment, GeoX* exploration risk and resource assessment software, and PetroMod* petroleum systems modeling software.

In Mexico, Statoil Gulf of Mexico LLC Exploration signed an agreement to license a large part of the WesternGeco Campeche deepwater wide-azimuth (WAZ) multiclient project. This three-year project is the first WAZ multiclient broadband survey in Mexican waters of the Gulf of Mexico and follows the government's opening of licensing rounds to non-government companies for the first time. The Statoil license also includes collaboration with WesternGeco in the seismic processing phase.

In Kuwait, the Kuwait Oil Company awarded Schlumberger a $22 million contract to supply and install high-pressure, high-temperature liner hangers for deep-gas wells in the Jurassic Gas development project. This technically challenging development requires specialized, highly reliable equipment to operate in complex wells up to 20,000 ft in depth.

Statoil, Inc. awarded Schlumberger a four-year contract with two one-year extensions for tank cleaning and waste handling services for all its supply vessels. The estimated $100-million contract includes supply of the AUTOMATIC TANK CLEANING (ATC) LITE* system. This trailer-mounted system recycles wash water and waste fluids and provides an easily operated alternative to conventional cleaning. Fully automated, the ATC LITE system reduces staff exposure to health, safety, and environmental risks.

Pretax operating margin					24.2	%			26.4	%			30.1	%		-230 bps			-600 bps
Decremental operating margin																56	%		42	%

Reservoir Characterization Group revenue of $2.2 billion declined 7% sequentially, primarily due to sustained cuts in exploration spending, the start of the seasonal winter slow-down, currency weakness, and operational disruptions from exhausted customer budgets that impacted Wireline activities, particularly in the Europe/CIS & Africa and Middle East & Asia Areas. This decline was partially offset by marine seismic surveys and multiclient seismic license sales in Mexico. Year-end product and software sales were largely muted compared to previous years.

Pretax operating margin of 24.2% declined 230 bps sequentially as the contribution of high-margin multiclient seismic sales was more than offset by a decline in high-margin Wireline services. Decremental operating margin was higher than the previous quarter at 56% as activities were affected by abrupt operational disruptions that offered limited prospects for prompt cost adjustments.

During the quarter, a number of Reservoir Characterization technologies helped characterize complex reservoirs, optimize well production and reservoir recovery, and improve operational efficiency.

In Iraq, Wireline introduced LIVE PL* digital slickline production logging services for the Rumaila Operating Organization in the Rumaila Field. LIVE PL technology provided real-time production logs on wells where memory logging was previously the only option. The planned shut-in time for the operation was 400 hours, yet only 100 hours were required. As a result, the customer resumed production 12 days earlier than planned thereby avoiding 18,000 bbl in deferred production.

Offshore India, Wireline introduced P3* post-perforating technology to clean out perforations in a well for ONGC Ltd.India in the B-193 Field. In high sour gas conditions, P3 created a high dynamic underbalance after two runs in a low-pressure reservoir with balanced well-bore fluids. P3 technology used the PURE* clean perforations system to remove perforation debris and crushed-zone damage. As a result, the customer achieved a 330% increase in oil production and a 250% increase in tubing head pressure.

In the UK sector of the North Sea, Wireline used a combination of technologies for TAQA to perforate an extremely long wellbore in the Pelican Field. StreamLINE* polymer-encapsulated wireline monocable, which has a friction coefficient that is one-half of the equivalent standard braided line to reduce cable tension, facilitated deployment of the 293-ft and 3,912-lbm perforating string and, thanks to its polymer coating, reduced the risk of damaging the anti-corrosive liner. In addition, PowerJet Nova* extradeep penetrating shaped charges increased penetration in the stressed rock formation for maximum water injection. As a result, the customer achieved rig-time-related savings by completing the well in two runs instead of seven.

In the Norwegian North Sea, Wireline deployed heterodyne distributed vibration sensing (hDVS) technology for Statoil in several wells in the Kvitebjørn field. The hDVS technology enabled vertical seismic profile surveys to be recorded using optical fibers already installed in the well, thereby saving rig time. These surveys were acquired while using VSI* versatile seismic imager technology, which delivered accurate calibration information and near-borehole imaging to improve seismic understanding for ongoing near-field exploration. The combined VSI and hDVS operations were completed in 20 hours compared to four days using conventional vertical seismic imaging methods. As a result, the customer obtained additional seismic calibration information, and potentially saved $1.5 million, equivalent to three days of rig time.

In Venezuela, Completions and Testing introduced P3 PURE post-perforating controlled implosions to clean out perforations for PDVSA in a well in the El Furrial Field East Venezuela. Previous attempts by the company to establish better communication with the reservoir were unsuccessful. Coiled-tubing deployed P3 technology allowed a deep and efficient chemical stimulation of the selected reservoir intervals. Following the treatment, the customer benefitted from wellhead pressure increases of up to 1,500 psi.

In Algeria, Wireline introduced Saturn* 3D radial probe technology for Sonatrach to sample low permeability reservoirs with a high overbalance. Saturn technology extends formation testing to fluids and reservoir environments that were formerly inaccessible with conventional formation testers. For the first time, the customer was able to overcome differential pressure limitations by imposing a 7,500 psi differential on the tool and sample fluid at mobilities as low as 0.02 mD/Cp. As a result, depleted sections of the reservoir were identified, thus improving Sonatrach's understanding of the subsurface.

Offshore Brazil, the Reservoir Characterization Group helped Petrobras complete the first worldwide pre-salt deepwater formation evaluation wireline logging job with managed pressure drilling (MPD) services. Schlumberger well head pressure control equipment integrated for the first time into the MPD system, successfully allowed two openhole logging runs with 150 psi controlled wellhead pressure. This technology was important in reducing safety risks during formation evaluation. As a result, the customer now has vital information to characterize the reservoir and lower the risk of field development.

In Abu Dhabi, SIS successfully completed deployment of the Exploration & Production Information Solutions (EXPRIS) project for Abu Dhabi National Oil Company and its operating companies. Awarded to SIS in 2012, the contract entails deployment to more than 1,000 users, providing them with efficient and intuitive access to a variety of geophysical, geological, drilling, well completion, fluid sample analysis, well testing, and production field data. EXPRIS is built on ProSource* E&P data management and delivery systems and allows users to apply the data in other technical applications, thus enhancing user productivity as well as team integration.

Drilling Group revenue of $3.0 billion decreased 8% sequentially, primarily from a drop in drilling activity, persistent pricing pressure, the start of the seasonal winter slow-down, currency weakness, and operational disruptions from exhausted customer budgets that impacted Drilling & Measurements and M-I SWACO revenues, mainly in the Europe/CIS & Africa and Middle East & Asia Areas.

Pretax operating margin of 16.7% contracted 173 bps sequentially as revenue declined on pricing weakness and abrupt operational disruptions that resulted in a decremental operating margin of 38%.

New Drilling Group technologies delivered better performance by improving efficiency, optimizing well placement, and assuring wellbore integrity in a number of regions during the quarter.

In Mexico, Drilling & Measurements introduced GeoSphere reservoir mapping-while-drilling service for PEMEX in a horizontal well in an oilfield offshore Tabasco, which is renowned for its geological complexity and drilling risk. Previous campaigns using conventional drilling methods often encountered subsurface risks such as shale-outs, which made accurate well placement very challenging. Deployed for the first time in this field and for PEMEX in Mexico, GeoSphere technology reduced geological uncertainty by mapping the target sand layers along the entire reservoir section, which enabled optimal steering of the well inside the reservoir. The information GeoSphere technology provided also allowed precise evaluation of the structure and thickness of the lithology, which helped update the geological model and optimize the design and planning of subsequent wells in the area.

Offshore Norway, Drilling & Measurements used the PowerDrive X6* rotary steerable system for Statoil, Inc. to drill a well in the Valemon Field. PowerDrive X6 technology reduces drilling torque to improve performance and reliability. In addition, the IDEAS* integrated drillbit design platform provided a four-dimensional simulation of the cutting interface, which enabled StingBlade conical diamond element bit technology to be combined with the PowerDrive X6 system to improve footage drilled and rate of penetration (ROP). The ROP not only exceeded the customer's expectations, but established a 24-hour drilling record of 52.69 m/hr.

In the Norwegian sector of the North Sea, Bits & Drilling Tools used Neyrfor TTT* thru-tubing turbo drill for BP to re-establish oil production in a well in the Ula Field. Neyrfor TTT technology removed an influx of more than 60 m3 of oil-based drilling fluid from the well and established underbalanced conditions with a high nitrogen ratio. In addition, CIRP* completion insertion and removal under pressure equipment perforated a 900-m section of the well such that the perforating guns were removed without killing the well. The customer achieved an increase in oil production, which was three times more than originally expected.

In Romania, Lukoil Overseas used Schlumberger Seismic Guided Drilling* (SGD) while-drilling integration of surface seismic and downhole measurements, in combination with Geoservices real-time mud-weight window monitoring services, in the successful drilling of two wells in the Black Sea. In the first well, SGD service predicted a pore-pressure ramp and subsequent benign pressures, while also correcting the reservoir target position by more than 40 m, enabling the customer to drill to total depth (TD) as per the drilling plan. In the second well, SGD pressure estimates helped determine the optimum mud weight, improving target positions by up to 60 m and enabling the customer to reach TD in the reservoir considerably ahead of schedule.

In Russia, M-I SWACO used SCREEN PULSE fluids and cuttings separator technology for Investgeoservis CJSC. SCREEN PULSE technology is a retrofit installation that collects residual drilling fluid from cuttings on the shale shakers and returns the fluid back to the circulating system. This technology was used on two separate projects and allowed the customer to reduce drill waste volumes by 26%, which helped lower costs for dilution, treatment, transportation, and disposal.

In Kazakhstan, Drilling & Measurements introduced StethoScope* formation pressure-while-drilling service on two horizontal wells drilled for Karachaganak Petroleum Operating B.V. This technology secured real-time pressure measurements to generate profiles that were combined with other logs to model dynamic reservoir pressure, which is vital to optimizing recovery. The customer benefited from estimated savings of $700,000 due to a reduction in rig time, while mitigating operational risk.

In Iraq, Schlumberger used StingBlade conical diamond element bit technology for BP to overcome the need for multiple drilling runs in wellbores in the Rumaila Field. StingBlade technology helped increase footage drilled and ROP due to its superior wear resistance. As a result, the customer drilled an entire well section in a single run with a 63.5% improvement in ROP compared to the average offset wells' ROP, saving the customer more than three days of rig time.

In China, Drilling & Measurements used a combination of formation evaluation, well placement, and drilling optimization technologies for Newfield Exploration Limited to drill nine well boreholes in the LF7-2 field development campaign. EcoScope^†* multifunction logging-while-drilling, PeriScope* bed boundary mapping, and PowerDrive Orbit* rotary steerable system technologies were used to optimally steer the horizontal boreholes near the top of the reservoir in single runs, eliminating the need for sidetracks. The campaign's drilling performance also improved overall ROP, which enabled the customer to save 11 days of drilling time, representing a 10% time savings versus the initial drilling plan.

Production Group revenue of $2.7 billion decreased 10% sequentially with 80% of the decrease attributable to a further decline in North American land activity as exhausted customer budgets led to a further decline in rig count and increased pricing pressure. Market pricing for pressure pumping services dropped to even more unsustainable levels.

Pretax operating margin of 11.3% increased 24 bps sequentially despite lower activity and increasing pricing weakness in pressure pumping services. Sequential decremental operating margin improved to 9% as the decline in pressure pumping margin was largely offset by the combination of accretive margin contributions from Schlumberger Production Management projects in Latin America and higher net earnings from the OneSubsea joint venture.

New Production Group technologies helped customers meet technical challenges during the quarter by accelerating production, enhancing recovery, and increasing operational efficiency.

In Southeast Kuwait, Well Services completed a large-scale fracturing treatment using HiWAY* flow-channel technology for Kuwait Oil Company in a well in a sandstone reservoir in the Greater Burgan Field. HiWAY technology helped overcome the placement and proppant flowback challenges commonly encountered with conventional hydraulic fracturing methods. After the fracturing treatment, the well's oil production reached a natural continuous flow of 3,000 bbl/d.

In Tunisia, Well Intervention performed stimulation treatments in two wells for Serept in the Ashtart Field. The high-temperature reservoir required precise fluid selection while the focused, high-energy fluid streams of the Jet Blaster* engineered high-pressure jetting service enabled accurate placement of the stimulation fluid deep inside the reservoir matrix. As a result, post-treatment production exceeded customer expectations with a fourfold increase in one well and doubled production in the second.

In Ecuador, Well Services deployed the DualSTIM* fracturing service as part of a recompletion strategy for Petroamazonas to address declining production in the Parahuacu Field. DualSTIM technology used water-based fluids to stimulate this highly depleted reservoir that has moderate permeability and a clay content sensitive to high water concentrations. Since the start of the multiwell campaign in 2014, DualSTIM technology combined with hydraulic fracturing has resulted in incremental cumulative oil of more than 400,000 bbl.

Also in Ecuador, Well Services used Invizion* integrated zonal isolation services for the Shushufindi Consortium in a well in the Aguarico Field. Invizion technology tracked and evaluated cementing operations in real time, which facilitated interpretation of results. In addition, the technology allowed integration of the well data to identify zonal isolation issues as well as an evaluation of potential short- or long-term impact.

Elsewhere in Ecuador, Well Intervention used OneSTEP* simplified sandstone stimulation technology for Orion Energy to remove damage and overcome a fluid conveyance problem in a well without compromising electrical submersible pump integrity, which made conventional stimulation treatments unviable. OneSTEP technology uses only one fluid solution to remove well damage for a more uniform stimulation of sandstone reservoirs with less risk of disintegrating the rock. The customer doubled production while maintaining basic sediment and water at 0.1%.

Offshore Gabon, Schlumberger Completions utilized an integrated solution for VAALCO Energy to complete three horizontal wells in the development of the Etame Field. The solution included reservoir drilling fluids, completion and artificial lift technologies for this openhole, gravel-packed completion. In particular, the AquaPac* integrated water-packing system used brine to carry and place gravel around preinstalled screens and prevent sand production. FloPro NT* technology was used to transport high volumes of cuttings from the reservoir section. Operationally, the wells were gravel-packed with well productivity meeting customer expectations.

As a result, Schlumberger recorded a $530 million charge during the fourth quarter associated with these headcount reductions and the ILOA program.
		Asset impairments and restructuring charges:
		As a result of oil and gas industry market conditions that have continued to deteriorate and its impact on the activity outlook, Schlumberger determined that carrying values of certain assets were no longer recoverable and also took certain decisions that resulted in the following impairment and restructuring charges during the fourth quarter of 2015:

				--	$776 million of fixed asset impairments primarily relating to underutilized pressure pumping and other equipment in North America, as well as certain lower-tier drilling rigs.
				--	$269 million to write-down the carrying value of certain inventory, primarily in North America.
				--	$182 million to reduce the carrying value of the remaining investment in an SPM project in Colombia, as a result of the recent decline in commodity prices. Considering also that the project is approaching the end of its contractual term and its revenue stream is directly linked to oil prices.
				--	$177 million associated with facilities, including the expected sale of certain properties and the termination of certain leases.
				--	$77 million relating to assets that are no longer recoverable as a result of geopolitical issues in certain countries in the Middle East.
				--	$41 million relating to contract termination costs.
				--	$84 million of other charges associated with the current market conditions, including $40 million relating to an other-than-temporary impairment of marketable securities and $15 million relating to the impairment of an equity-method investment.
				Schlumberger does not expect to incur any significant cash expenditures as a result of these asset impairment and restructuring charges.
