Cobalt
International Energy, Inc. has plugged and abandoned its North Platte
#2 appraisal well in the deepwater U.S. Gulf of Mexico due to a seal
failure in the riser connection system.The well, which was being drilled with the Rowan Reliance drillship, was at a depth of 20,701 feet when the problem with the riser was detected.
The well was permanently abandoned prior to reaching any geological targets.
Cobalt is currently permitting the North Platte #3 well approximately 200 feet from the surface location of the North Platte #2 well. Assuming timely receipt of permit approval, Cobalt anticipates spudding the North Platte #3 well within two weeks and continues to expect well results in the second half of 2015.
The North Platte #1 discovery well was drilled in 2012 and encountered over 550 net feet of oil pay in multiple high-quality Inboard Lower Tertiary reservoirs.
Cobalt, as operator, holds a 60% working interest in North Platte.
