3:33 The challenge
- →During conventional P&A, tubing parted at ~1,000 ft; milling to dress the top failed.
- →Only a ~10 ft window below the stuck packer for a precise intercept.
- →Target builds ~18°/100 ft DLS immediately below the packer.
- →High-resistivity salt formation and oil-based mud, with poor target surveys at ~500-ft intervals.
Our solution
DeadAhead™ wired-pipe AMR-While-Drilling, the world's first commercial deployment. Continuous live ranging from the BHA through a six-phase intercept, holding 5–10 ft separation to land on the exact planned depth.
~2 weeks saved vs. wireline AMR · ~$2M direct savings · 10+ runs avoided
The result
~8,640 ft
MD, intercepted at exact planned depth
- ·Located target at ~3,500 ft
- ·Held 5–10 ft separation over ~5,500 ft of continuous ranging
- ·Well killed via bullhead
- ·Milled, re-entered and cemented under regulator witness
