Schlumberger worked with operators to boost production performance in Texas shale by implementing a consortium that evaluates horizontal wells. This consortium involves the Unconventional Reservoir Optimized Completion (U-ROC) workflow, which enables integration of reservoir, stimulation, and production data; the Mangrove engineered stimulation design in the Petrel platform, a hydraulic fracturing simulator that integrates with a seismic-to-stimulation workflow; and ThruBit logging services, technology designed to acquire and deliver a full suite of wireline logs. This combined offering, in turn, produces an engineered completion design strategy.

By using this engineered completion strategy, four Eagle Ford operators boosted perforation efficiency up to 82% in their wells, which resulted in a $1.5 million increase in net present value for their first year of production. Additionally, Clayton Williams Energy, Inc. was able to increase the oil production of their horizontal wells by 39% in the Wolfcamp Shale play in the Permian Basin. This demonstrates the dramatic impact that an intelligent engineered completions approach can have on increasing reservoir contact and productivity for shale wells. This approach, in turn, can be applied to any stimulation program to optimize completions.
