Multiwell batch casing, 'disruptive' DGD technologies, Arctic jackup design advance offshore drilling

摘要

A 25-well batch-casing program in the deepwater Gulf of Mexico (GOM) has exceeded targets around safety and efficiency over a six-month development campaign that logged zero nonproductive time (NPT) and HSE incidents related to tubular-running services (TRS) while reducing running costs by 25%. The results are the product of a collaborative effort begun early in the planning process and by using new technology. Specialized equipment optimized procedures, and mechanized tubular-running operations were developed.
