Game-changing P&A approach changed days per well to wells per day
In early 2017, a major operator began an asset retirement campaign, abandoning 3,000 to 4,000 wells on 311 platforms in the Gulf of Thailand.
Plug and abandonment (P&A) operations were split into two phases―lower (reservoir) and upper (intermediate) abandonment. The scope of work included four different well types with pipe sizes ranging from 2 7/8-in. tubing to 30-in. conductors.
Days per well reduced
The operator contacted Baker Hughes, a GE Company (BHGE) to perform P&A operations on 20 shallow-water wells on the first platform. This included tubing pulling, casing cutting and pulling, cementing services, mechanical plug setting, and well integrity evaluation. These wells were constructed with a 9 5/8-in. x 7-in. x 2 7/8 in. casing configuration.
