In Russia, Integrated Drilling Services (IDS) decreased operation time by 103 days in three extended reach wells for Rosneft-Sakhalinmorneftegaz on Sakhalin Island. The technologies used included:
In addition, cumulative production for these three wells in 2016 was 47% higher than initially expected.
In West Texas, Schlumberger enabled Parsley Energy to reduce the average days required to drill a well by 17% in the Midland and Delaware basins. The drilling technologies used included:
The reduced drilling time is based on drilling 80 wells during the past 12 months and is compared with the previous year. In addition, the customer reduced the average total drilling cost per lateral foot by 30%. (Image: Courtesy University of Texas Libraries)
In South Texas, Integrated Production Services (IPS) enabled Lonestar Resources to produce up to 86% more hydrocarbon per 1,000 ft of lateral in 18 wells in the Eagle Ford Shale. This included use of the following technologies:
The results, which are compared with offset wells in two other fields, stem from IPS optimizing drilling, stimulation, and completion plans across long laterals.
In Iraq, Schlumberger increased oil production by 3,000 bbl/d for BP Iraq N.V. in a carbonate reservoir in the Rumaila field. This was the result of increasing water injectivity to 4,600 bbl/d by using:
These technologies selectively stimulated zones with low permeability.
In North America, BP awarded OneSubsea an engineering, production, and construction (EPC) contract to supply the subsea production system for the Mad Dog 2 development in the Gulf of Mexico. OneSubsea capital-efficient solutions includes:
In addition, Subsea 7, which collaborates with OneSubsea through the Subsea Integration Alliance, was awarded an engineering, procurement, construction, and installation (EPCI) contract for subsea controls, flexible risers, pipeline systems, umbilicals and associated subsea architecture.
