The advent of reservoir geomechanical models enables further levels of subsurface characterization by incorporating the complex interplays between finely characterized rock properties, detailed structural elements definition and pressure profile assessments. They enable field management strategies to account for the operational risks associated with a particular drilling and production plan. We present the use of high quality seismic inversion data and detailed sedimentological, petrophysical and structural descriptions to create a reservoir geomechanical model for a channelized turbidite reservoir in offshore West Africa. We aim at understanding the impact of reservoir production in altering subsurface stress conditions and the potential implications in observed drilling performances. We describe a systematic way to incorporate sedimentological models in the generation of seismic- driven mechanical property distributions (ultimately governing the stress state), and provide measures of impact when forecasting the field’s long term geomechanical risks, subsidence profiles and fault reactivation scenarios.
