Abstract

Integrating geomechanics with drilling fluid design successfully mitigates time-dependent wellbore instability in Middle East fields. Mud pressure penetration and the chemical potential gradient between the drilling fluid and the formation's in situ pore fluid are two of the mechanism that must be in balance to avoid time-dependent shale instability. The salinity of the drilling fluid must be high enough relative to the formation pore fluid for the chemical potential mechanism to counteract the mud pressure penetration. Some operators may have a geomechanical service provider perform a study of the geomechanical wellbore instability component while another service provider designs the drilling fluid. The geotechniques have been implemented in Al-Khafji Joint Operations, a joint venture between Aramco Gulf Operations and Kuwait Gulf Oil Co., which integrates drilling fluid design with geomechanics to address stress-induced effects and time-dependent fluid effects.
