MAX-BRIDGE bridging solution enabled drilling with water-based mud in challenging overbalanced well Results • Successfully drilled the well to TD of 4570 m (14,990 ft) despite differentially pressured zones causing two offset failures • Eliminated NPT by minimizing downhole losses and incidents of differential sticking Challenges - Changing pressure in highly depleted formations in 563 m- (1,847 ft-) section - Achieving a buildup of 0 o to 80 o in reactive shale and depleted zones - Extremely overbalanced conditions - Sloughing shale - Deviated wellbore BHGE solution • The BRIDGEWISE engineering software to design an optimized MAX-BRIDGE bridging system to strengthen the wellbore • Maintained the system despite overbalance conditions up to 5,800 psi during th
