Statoil has made an oil discovery in its Miocene Yeti prospect in the Gulf of Mexico (GoM), the company said in a news release.

“The Yeti discovery expands the proven subsalt Miocene play farther south and west of the Big Foot field,” said Jez Averty, Statoil’s senior vice president, exploration for North America. “We are analyzing data to determine the size of the discovery in order to consider future appraisal options.”

The Yeti discovery was made in Walker Ridge Block 160, about 15 km (9 miles) south of the Big Foot Field and 11 km (7 miles) from the Cascade Field, the release said.

Yeti was drilled with the Maersk Developer rig, a sixth generation semisubmersible. Statoil said in the release that its drilling efficiency with Yeti was among the best of any well drilled in Walker Ridge, achieving a rate of about 123 m (400 ft) per day.

The rig has moved on and is drilling Statoil’s Thorvald prospect in the Mississippi Canyon Block 814.

Statoil is the operator (50%) of Yeti. Partners are Anadarko (37.5%) and Samson (12.5%).
