Integrated Services Management Reduces Costs

In Ecuador, Schlumberger provided Integrated Services Management (ISM) to reduce total drilling time by 2 1/2 days, saving the customer $250,000 on the Tiputini project. The combined technologies and services included:

  • ONYX* polycrystalline diamond compact (PDC) cutter
  • Stinger* conical diamond element
  • Wireline Dielectric Scanner* multifrequency dielectric dispersion service
  • MDT* modular formation dynamics tester tool
  • PowerJet Nova* extradeep penetrating shaped charges

ONYX and Stinger technologies enabled better steerability and stability as well longer and faster runs. Operations were completed in 7 1/2 days instead of the expected 11 days.

Improving Tool Reliability

In the Middle East and Asia Area, the transformation program enabled reductions in equipment numbers and tool reliability repair costs for Schlumberger by using Technology Lifecycle Management (TLM). The use of TLM:

  • Decreased the overall cost of equipment repair by 48% and improved turnaround time by 21% in the first three months of operations at the Middle East Center for Reliability and Efficiency in Dhahran, Saudi Arabia, and
  • Improved source reliability for all WesternGeco sources by 47% from 2014 to 2016 in Australia

WesternGeco deployed its newly developed eSource marine seismic energy source on the Amazon Conqueror for a multiclient survey, which uses an acquisition technique that depends on high source reliability to ensure maximum operational efficiency.

Integrated Drilling Services Improves Performance

In the Gulf Cooperation Council (GCC) region, Integrated Drilling Services (IDS) delivered a 40% drilling performance improvement in the first three quarters of 2016 compared with non-integrated drilling services in similar fields. The improvement is based on the feet drilled per hour below the rotary table. This achievement was enabled by a combination of drilling technologies:

  • PowerDrive Archer* high build rate
  • PowerDrive Xceed* ruggedized rotary steerable systems
  • RigHour* multiwell drilling operational efficiency analysis
  • ROPO* rate of penetration optimization software

Schlumberger combined these technologies with integrated workflows overseen by multidisciplinary domain experts in the Saudi Arabia and Abu Dhabi Drilling Technology Integration Centers to reduce both drilling and overall development costs.

Meeting Customer Goals

In the Norwegian sector of the North Sea, Schlumberger deployed the GeoSphere* reservoir mapping-while-drilling service to increase the productivity of wells in the Balder field. The customer had two goals:

  • Avoid costly pilot holes in development wells that often failed to provide sufficient information to help land the producer wells, and
  • Avoid setting the casing in 1-in thin injectite sands

GeoSphere technology mapped the top of massive sands from more than 20 m total vertical depth above and detected the oil/water contact while landing the 12 ¼-in section before penetrating the reservoir. For the 8 ½-in reservoir section, the customer was able to plan a geosteering strategy ahead of the bit by combining seismic interpretation and GeoSphere mapping results.

Avoiding Costly Pilot Holes

In Egypt, Schlumberger used the GeoSphere* reservoir mapping-while-drilling service to eliminate a pilot hole in the Abu Rudeis field, which saved the customer $1.8 million. GeoSphere* reservoir mapping-while-drilling service:

  • Used deep directional electromagnetic measurements to reveal subsurface bedding and fluid contact details more than 100 ft from the wellbore, and
  • Helped manage the geological uncertainty and drilling risk

An unconformity at the top of the oil-bearing sandstone initially required a pilot hole to determine intermediate casing depth while pressurized shales above the target zone required a high mud weight that made penetration of the target sand challenging due to potential mud circulation losses.

Improving Service Delivery

The transformation program enabled an increase in reliability and efficiency as well as product and service delivery in Saudi Arabia. As a result,

  • The reliability of ImPulse* integrated MWD platform tools increased 240%
  • The reliability of adnVISION* azimuthal density neutron service tools increased by 47%

in the first six months of the CRE’s operation. Design, engineering, and maintenance teams at the Middle East CRE in Dhahran collaborated to create ruggedized modular housings for these measurement-while-drilling tools and decrease their susceptibility to movement and wear in a high-shock environment.

First Offshore Source Rock Hydraulic Fracturing

In the UAE, Schlumberger completed the first multistage, offshore source rock hydraulic fracturing treatments in the world. The eight jobs were completed in 40 hours with more than half a million pounds of proppant pumped. The technologies used included:

  • HiWAY* flow-channel fracturing technique
  • UltraMARINE* seawater-base fracturing fluid

stimulating low-permeability, high-stress source rock.

Reducing Rig Time

Offshore Indonesia, Schlumberger saved a customer approximately 6 1/2 days of rig time, equivalent to $5.1 million in cost savings. Using MZ-Xpress* systems to perform multizone fracturing and gravel packing over four zones of completion in a well:

  • Two systems were each installed in a single trip
  • The systems provided multizone sand control

The well had five producing layers across two different casing sizes.

Decreasing Maintenance Costs

In North Texas, the transformation enabled improvements in tool reliability and reduced maintenance costs. Six months after implementing prognostic health management (PHM) it achieved an estimated $6 million of savings in operation costs. This involved:

  • The Center for Reliability and Efficiency in Denton
  • Collecting real-time pump data from field locations

Prognostic health management is an engineering discipline focused on predicting the future condition of a component and/or system of components. It is based on the analysis of failure modes, detection of early signs of wear and aging in complex systems and components, and correlation of these signs with an aging profile (or model).
