Norway’s Statoil said Thursday that it made an oil discovery at its Miocene Yeti prospect in the U.S. Gulf of Mexico.

The Yeti discovery was made in Walker Ridge block 160, located 9 miles south of the Big Foot field and 7 miles from the Cascade field.

“The Yeti discovery expands the proven sub-salt Miocene play further south and west of the Big Foot field,” Statoil’s senior vice president of exploration for North America Jez Averty said.

The state owned company is currently analyzing data to determine the size of the discovery so it can consider further appraisal options.

Yeti was drilled with the Maersk Developer drilling rig, a sixth generation semi-submersible.

Statoil reports that its drilling efficiency with Yeti was among the best of any well drilled in Walker Ridge, achieving a rate of 400 feet per day.

The rig has moved on and is currently drilling at Statoil’s Thorvald prospect in the Mississippi Canyon block 814, Statoil said.

Statoil operates Yeti with a 50 percent stake.

Texas-based Anadarko holds a 37.5 percent stake in the prospect and Oklahoma-based Samson Offshore holds a 12.5 percent stake.
