4:14 The challenge
- →A prior concentric (through-tubing) P&A attempt could not set a reliable barrier.
- →A permanent barrier was required below the production packer (~1,970 m).
- →High-angle mill & re-enter into the target casing.
Our solution
Drilled the intercept well with GWD and passive magnetic ranging while drilling, backed by active wireline AMR. Target-well surveys proved accurate, so the team aimed deeper between runs, located the target, milled a window and re-entered for permanent abandonment.
Target located and re-entered, permanent barrier set below the packer
The result
~1,970 m
target MD, barrier intercept set below the packer
- ·Reviewed the failed concentric P&A and planned a precise intercept
- ·Accurate target-well surveys, fewer AMR runs required
- ·Located the target, milled a window and re-entered at high angle
- ·Permanent barrier set below the packer
