Completion Optimization and Field Development

Make your best production decisions with advanced time-lapse surveying techniques

Repeating borehole surveys like 3D vertical seismic profiles (VSPs) over a field can help you assess fluid and gas movements in the reservoir over time. Valuable insight can be gained about the effectiveness of injection and production operations, leading to improved reservoir-recovery decisions. Further, reservoir changes related to compaction or subsidence can be modeled and monitored. With a predictive geomechanical model and time-lapse calibration of the model, reservoir performance issues like reduction in permeability or fault reactivation can be mitigated.

Hydraulic-fracture monitoring and fracture optimization

Schlumberger geophysics domain experts can monitor microseismic events during a hydraulic-fracture treatment to optimize the current- and future-stage fracture treatments. Using real-time monitoring and proprietary software, Schlumberger geophysicists can offer real-time treatment recommendations during the pumping operation to help prevent screenout or to halt a stage that has already gone out of zone. Observing the results from one stage can lead to improved fracture design for future stages, leading to more-effective fracturing and ultimately better well production.  The complex interaction between natural and hydraulic fracture networks can be studied and evaluated in real time, feeding the geohazard evaluation for possible fault reactivation during fracturing and pumping stages.
