Baker Hughes, a GE company, has a new site. Want to see how we’re inventing smarter ways to bring energy to the world?
A customer wanted to plug and abandon (P&A) one of the deepest wells ever drilled in Vietnam. A competitor had attempted the P&A, but had failed after 4 days and many trial runs. The well had 20 in. (1 in. wall thickness [WT]) x 36 in. (2 in. WT) casing set at 2,172 ft (662 m) with water depth at 1,867 ft (569 m). The customer then called in Baker Hughes, who successfully performed the P&A in two days.
The customer had a second well needing a P&A, and hired Baker Hughes to do that job as well. After careful planning and preparation, the Baker Hughes team deployed our universal wellhead retrieving system (UWRS) for the Vetco Gray MS-700 high-pressure wellhead housing (HPWH) and HERCULES™ multistring cutter system to cut and recover the casing in one trip.
