Geomechanical Modelling, Seismic Pore Pressure Prediction And Wellbore Stability Analysis: Key Elements Demonstrated By An Offshore Exploration Case Study

A robust, field-specific geomechanical model (in situ stress, pore pressure and rock properties –<br>Figure 1) has proven to be an essential tool for the hydrocarbon industry. Constraining the geomechanical<br>model for any particular area provides valuable information for improved characterisation of the region, field<br>or reservoir. The geomechanical model can also help to support a development plan that optimises drilling and<br>production operations. The benefits of incorporating a geomechanical approach into the well planning phase<br>include predicting pore pressure, fracture pressure, wellbore stability and minimising the use of excessive mud<br>weights that may lead to formation damage.
