Geomechanics for the Reservoir

Manage geomechanical changes

Production and injection affects the levels of subsurface stress during the life of an oil or gas field and can cause severe field development and production challenges, such as compaction and subsidence, changes in reservoir permeability, water breakthrough, fault reactivation and breaches in caprock integrity. In the reservoir and the overburden, these geomechanical changes, combined with complex geology, can affect completion stability and cause casing collapse and sanding across the field. Time-lapse, or 4D geomechanical simulation is critical to understanding and predicting how reservoir properties will change throughout the life of the field.

Predict and calibrate

Schlumberger provides accurate predictions of reservoir behavior using the ECLIPSE, and Petrel software technologies. Predictions integrate data from a variety of sources—including 3D surface seismic, well logging, core data, and well test data, and can be calibrated with monitoring data such as 4D seismic, microseismic, repeat well logging, subsidence measurements, and wellbore stability events. A reservoir wide pore pressure distribution can be derived using velocity information from 3D seismic data and be calibrated with downhole pressure measurements (Modular Dynamics Tester).
