Anadarko, an independent oil and gas company from Texas, has struck oil at another appraisal well testing its 2009 Shenandoah discovery in the U.S. Gulf of Mexico.
Located in the Walker Ridge basin, south of Louisiana, the Shenandoah-4 appraisal well, spudded in the second quarter of the year, encountered more than 620 net feet of oil pay, moving the giant oil discovery a step closer toward development.
The Shenandoah-4, was drilled to confirm the lateral sand quality and continuity of reservoirs found in Shenandoah-2 appraisal well, which encountered more than 1,000 net feet of oil pay in Lower Tertiary-aged reservoirs.
According to Anadarko, the Shenandoah-4, the third appraisal well in the drilling campaign, is located approximately 800 feet updip and 0.7 miles northwest of Shenandoah-2. Anadarko, in its third quarter statement on Tuesday, said operations continued after the quarter close, with the partnership preparing to obtain whole-core across the reservoir interval.
The original Shenandoah #1 discovery well was drilled in early 2009 on Walker Ridge Block 52 and encountered more than 300 net feet of Inboard Lower Tertiary oil pay.
Anadarko, which describes the Shenandoah project as one of the largest discoveries in the company’s history, is the operator of the project with a 30 percent stake.
Other partners in the project are ConocoPhillips (30%), Cobalt International (20%) Marathon Oil (10%), and Venari (10%). According to projections by Cobalt (late 2013), the partnership aims to bring the Shenandoah field to production by the end of the decade.
