Anadarko Reports Additional Pay at Gulf of Mexico, Mozambique Prospects
An appraisal well at the deepwater Gulf of Mexico Vito prospect encountered more than 600ft of oil pay in subsalt Miocene sands, Anadarko announced Monday, 22 March. The sidetrack appraisal well, drilled to a total depth of 31,000ft in Mississippi Canyon block 940, is about a mile away from the 2009 Vito discovery well. The well is in water depths of approximately 4050ft.
Shell operates the Vito field with 55% working interest. Anadarko, the initial operator, holds 20% interest and Statoil has the remaining 25% interest.
Anadarko senior vice president of worldwide exploration Bob Daniels called the appraisal well ‘an important step in confirming our geologic models of the area and transitioning this field from exploration to a potential stand-alone development.’
Anadarko was the apparent high bidder on 48 tracts in last week’s Central Gulf of Mexico lease sale 213, representing expenditures of about $128 million. If approved, the new leases will bring the company’s GoM access to 618 blocks covering about 3.5 million acres. This year, Anadarko plans to drill four to six exploration wells and three to four appraisal wells in the deepwater GoM, the company said.
The company also announced that the Windjammer discovery well offshore Mozambique reached a total depth of 16,930ft and encountered an additional 76 net feet of natural gas pay, bringing the total net feet of gas pay in Windjammer to more than 555. Anadarko operates the discovery, in 4800ft water depths 30 miles off the coast of Mozambique, with an approximate 43% paying interest.
The company will next move the Belford Dolphin drillship 50 miles south-southeast to drill the Collier prospect, Anadarko said.
