Evaluation of Driving Forces on Wellbore Stability in Shale Formations
Author(s): Luqman Ali Khan, Abdul Haque Tunio
Drilling into chemically active shale formations is critical due to the time-dependent interaction between the drilling fluids and the shale. The physical models shown thus far have sophisticated input parameters that necessitate advanced experimental facilities, which are expensive and, in most cases, unavailable. Due to the chemical active shale formation drilling through water base mud is a challenge for petroleum industry. So, in shale formations well instability is a major problem due to the physiochemical interactions of drilling fluids with the formation. In this paper, driving forces i.e., poroelastic, chemical and thermal effects are evaluated for the investigation of dominant driving forces.
