Maintain a stable wellbore

The Drilling Geomechanics services combine prejob offset analysis, earth model building, and remote expert support during operations to manage geomechanics challenges. It is designed to address increasingly complex geomechanical environments, where the subsurface pressures, stresses and rock properties are uncertain and making the right decisions to maintain a stable wellbore is extremely challenging.

Predrill planning

The Mechanical Earth Model of the subsurface constructed in the predrill phase is used to define optimized wellbore stability boundaries for a proposed trajectory. Hazards associated with the trajectory are identified in the well plan. This well plan is developed by a multi-disciplinary team, presenting wellbore stability information for use by all stakeholders involved in the well construction.

Monitoring and predicting

As new data become available the well plan is updated to ensure that it remains current. Changes in the geological sequence or changes to pore pressure and wellbore stability boundaries may necessitate changes to the well plan such as moving a casing point.

During drilling operations, geomechanics experts analyze in real time all available drilling, petrophysical, mud, seismic, and geological data to visualize current downhole conditions. The real-time information acquired from logging while drilling tools combined with the surface data including solids and gas monitoring from wellsite based Geoservices experts, and drilling parameters enables the expert team to reassess the hazards to provide the best information to take preventive or remedial action.
