Alaska Oil and Gas Conservation Commission data is showing the first record of a completed winter exploration well this year, ConocoPhillips’ Tinmiaq No. 7. AOGCC records show the well was completed Feb. 22 at a total depth of 4,036 feet, and a true vertical depth of 4,075 feet.

The well is one of four the company has permitted for drilling this winter at the company’s Willow discovery on the western side of Greater Mooses Tooth in the National Petroleum Reserve-Alaska: Tinmiaq 7, Tinmiaq 8, Tinmiaq 9 and West Willow 1.

The company, which planned to use three rigs for exploration drilling this winter, has also permitted two penetrations, Putu 2 and Putu 2A, in the southern Colville River unit and two penetrations, Stony Hill 1 and Stony Hill 1A, south of CD5.

ConocoPhillips drilled the Tinmiaq 2 and Tinmiaq 6 on the western side of Greater Mooses Tooth in 2016, with a 12-hour test at Tinmiaq 2 producing 3,200 barrels per day of 44 degree API well.

In 2017 the company announced a discovery of some 300 million barrels of recoverable oil at Willow.

The company has facilities under construction at the Greater Mooses Tooth 1 pad in NPR-A and plans first oil at the end of the year. Permitting is underway for the Greater Mooses Tooth 2 pad.
