Cobalt International Energy Inc. (NYSE: CIE) plugged and abandoned its North Platte #2 appraisal well in the deepwater U.S. GoM, the company said April 9.
A seal in the riser connection system failed, the company said.
The Rowan Reliance drillship was drilling North Platte #2 at 20,701 ft when the problem was detected, the company said, noting that the well never reached geological targets. The North Platte #3 is currently being permitted about 200 ft from North Platte #2’s surface location. Assuming timely receipt of permit approval, Cobalt plans to spud it within two weeks.
The North Platte #1 discovery well was drilled in 2012 and encountered over 550 feet of net oil pay in multiple high-quality Inboard Lower Tertiary reservoirs. Houston-based Cobalt, as operator, holds a 60% working interest in North Platte.
