Cobalt International has encountered oil at its North Platte #4 appraisal well in the deepwater Gulf of Mexico, with plans to drill a second sidetrack, as the company ups its estimates of recoverable hydrocarbon resources at the prospect.

Cobalt’s North Platte #4 appraisal well encountered approximately 650ft of net oil pay, with initial results indicating high quality inboard Lower Tertiary Wilcox reservoirs on the eastern flank of the field, says the company.

According to Cobalt, current estimates of recoverable hydrocarbons at North Platte is now greater than 500 MMboe, with the potential to grow larger once water contacts have been established across the entirety of the field.

Appraisal operations continue to further analyze the extent of the eastern flank.

“The well encountered oil and has confirmed that reservoir quality sands are present across the entirety of the eastern flank,” says Cobalt. “Cobalt now plans to drill a second sidetrack to core and gather fluid samples, and expects to complete these operations in Q2.”

“Reservoir characterization, fluid analysis and modeling studies are ongoing to better understand reservoir continuity, productivity and the potential resource range in order to optimize the development of the North Platte field,” says Cobalt.

Cobalt operates North Platte with 60% working interest. Its partner on the project is Total E&P (40%).
