Details of our TRIDENT System performing inner string casing recovery, first the 9 5/8" casing is cut, circulated and then recovered to surface before a cement plug can be placed in the well.
Once that has been completed a 13 3/8" TRIDENT System is deployed to cut and circulate the 13 3/8" casing, this is then repeated on the 20" before dual casing recovery is achieved.
This operation drastically reduces the amount of trips downhole, providing not only time efficiencies but also avoiding unnecessary CO2 emissions from reduced rig operating time.
