3:33 The challenge
- →A well blowing dry gas through the 16" drive pipe just above the waterline.
- →Flow worsened, a large washout in the casing venting gas, water and sand.
- →Dual completion; barge-only access in inland-water marsh, with a tropical storm approaching.
- →Flow >750 mscf/d; kill path, intercept depth and dynamic-kill parameters undefined.
Our solution
Gunnar well-control engineers mobilized to site: installed a diverter sleeve on the 16" casing to manage the flow, ran steady-state dynamic-kill calculations across flow rates and mud weights, and engineered a full relief-well contingency plan (surface location, directional trajectory, ranging program, intercept depth/angle).
Well killed with 16 ppg mud, no relief well required
The result
16 ppg
kill mud, perf-and-kill at ~8,170 ft; well controlled
- ·Diverter sleeve installed on the 16" casing to manage surface flow
- ·Short string killed with 12 ppg mud; ~493 bbl pumped on the long string
- ·Dynamic-kill modeling and a full relief-well plan prepared as contingency
- ·Brought under control without drilling the relief well
