- Offshore well, Brunei, southeast Asia
- Gravel pack, work string and wash pipe stuck across 5 1/2-in screens
- Narrow 2.5-in ID restriction
- 72° inclination
- Conventional pipe recovery services not possible due to complex geometries of stuck equipment
- Provides a non-ballistic, non-chemical solution to sever downhole tubulars
- Fast mobilization of equipment
- Reduces operational time
- Efficient cut with minimal debris and no outer string damage
- Surface visualization and cut confirmation
- Multiple cuts capability in single run
- Mechanical Pipe Cutter (MPC) tool was rapidly mobilized and deployed
- Deployment method optimized through propriety Deployment Risk Management (DRMTM) process
- Pump down deployment to mitigate 72° inclination
- Produced a clean, precise cut in 4-in drillpipe allowing recovery of the work string, resulting in a successful fishing operation
An operator at an offshore rig in Brunei was installing a single trip gravel pack work string and wash pipes across 5 1/2-in screens. Immediately after the first zone had been packed and completed, the entire string got stuck.
After evaluating the scenario, the option with a higher potential for success in the recovery was a fishing operation that required a clean cut in the 4-in drillpipe at the first joint from the bottom. This would allow running in with a heavy fishing assembly to catch, pull, hammer and release the packed string.
