This paper show method of utilizing seismic-driven geomechanical earth model (MEM) to describe the rock properties and in-situ stress in reservoir geomechanics and production drilling. Seismically derived horizons and seismic velocities were used to generate 3D MEM. 3D geomechanical model was built using a combination of wellbore geomechanics, geological structures, lithofacies derived from seismic inversion and elastic properties from well and seismic data from Bonga Field, Niger Delta. The study was able to estimate rock mechanical properties in the inter-well space and full 3D subsurface in-situ stress distribution. The study also shows the usefulness of 3D geomechanical model in the analysis of well trajectories for optimal well placement.
