A long open hole section with a 1200 meter fish, entirely in salt, left shallow formations and the casing shoe at 463 meters exposed to the reservoir at 1470 meters TVD. Fishing was unsuccessful and a relief well was planned to intersect below the fish to plug and abandon the open hole across the reservoir.
During a workover to repair a casing shoe leak, a gas utility sidetracked out of 5 1/2” casing in an injection/withdrawal well due to a severe dogleg. Subsequent attempts to re-enter the casing were unsuccessful.
A brine well next to the Ohio River needed to be plugged and abandoned because of a loss in casing integrity. After several unsuccessful attempts to plug the well from surface, a relief well intersection was determined to be the only viable method.
Successful kill of a surface blowout: After several attempts to kill the well from surface, a relief well intersection was determined to be the only viable kill method.
Before a depleted reservoir could be converted to gas storage, a gas transmission company needed to re-abandon or complete an old “dry hole” near the center of the reservoir. 8 5/8” casing had been pulled to 435 feet and open hole existed from 1000 feet to the top of the storage sand at 3100 feet. Two previous attempts to re-enter the top of the casing stub at 435 feet had failed and a sidetrack had been drilled to 1000 feet.
