Performance Report: Solving Cyclical Fatigue Forces Across a Weak Formation in an ERD Well Offshore Malaysia Peninsula

Date: 9/18/2013

Drilling this extended-reach (ERD) well with a highly deviated production hole section carried some major drilling risks and operational challenges related to wellbore instability, high torque and drag, poor hole cleaning, cutting bed formation, differential sticking and excessive equivalent circulating density (ECD). Reservoir depletion had led to changes in rock stress and a reduction in pore pressure, creating the additional complexities of wellbore stability and ECD management.
