During a large-scale platform-based P&A campaign, the operator required the efficient cutting and recovery of triple casing string, in a single operation. The scope included cutting through the 13⅜” intermediate casing, 20” casing, and 30” conductor, with all three strings cemented together exhibiting significant eccentricity.

Multi-string cutting in platform environments presents inherent challenges, including harsh weather conditions, a lack of well data, and the need for safe, controlled recovery. The operator sought a proven solution capable of delivering reliable performance while minimizing operational time and intervention complexity.

Wellbore Integrity Solutions (WIS) ProLATCH™ casing cutting and retrieval system incorporates high performance knife designs that have shown significant improvement in subsea applications, with reduced cut times and increased probability of triple cut in a single operation.
