1. The 9-5/8” casing will be recovered using a single trip cut and pull system.
Note the depth of the cut from RKB and proposed BHA.
2. The 13-3/8” casing will be cut using a marine swivel. Note the depth of the cut from RKB
and proposed BHA’s.
3. The 20” x 30” will be cut and pulled using a single trip cut and pull system.
Note the depth of the cut from the RKB and proposed BHA for this cut. If spacer subs are required note the sub length.
