Optimizing extended reach drilling in deepwater West Africa
An optimized BHA, detailed planning and advanced modeling enabled the team to drill the ERD well with a single BHA per interval. A challenging 12¼-in. tangent interval was drilled to reach the top of the pay zone keeping an 85° sail angle, setting a regional record of 11,150 ft flawlessly drilled from casing to casing in a single run.
