Case Study: Dual Bottomhole Pressure Management for Differential Sticking Mitigation & Hole Instability During MPD Liner Operations in Contrasting Pressure Regime

Maintaining wellbore stability and avoiding differential sticking in HPHT wells becomes increasingly challenging when narrow and conflicting pressure regimes coexist across the open hole. This challenge was encountered during the execution of a 7-in liner in a 35° inclination well drilled to 5,400 m MD under HPHT con...
