Anadarko Appraisal Extends Shenandoah Field Boundary

Anadarko Petroleum Corp. drilled a successful appraisal well at the Shenandoah field in the U.S. Gulf of Mexico, one of its Shenandoah partners reported Wednesday.

Venari Resources LLC said that Anadarko encountered more than 1,000 net feet of high-quality oil pay in the Shenandoah No. 5 well at Walker Ridge Block 51. Drilled in approximately 5,900 feet of water to a total depth of 31,100 feet, the Shenandoah No. 5 well encountered the oil pay in the Lower Tertiary Wilcox sands.

Results of the Shenandoah No. 5 well, drilled up-dip of the Shenandoah No. 2 appraisal well, extends the field’s reservoir boundaries further east, Venari reported in a July 27 press release. Venari expects the next appraisal well, Shenandoah No. 6, to spud later this year to further determine the field’s full resource potential.

Anadarko plans to run a production liner in the Shenandoah No. 5 appraisal well and secure the well for future production operations, Anadarko said in its second quarter 2016 operations report. During the second quarter, the company increased its working interest in Shenandoah to 33 percent and added several new exploration opportunities to the portfolio by participating in a preferential-right process, Anadarko said in a July 26 press statement.

The Shenandoah field is located on Walk Ridge Blocks 51, 52 and 53.

Anadarko is the operator of Shenandoah. Other partners include ConocoPhillips Company with 30 percent interest and Cobalt International Energy L.P. with 20 percent interest.

Venari now holds 17 percent working interest after acquiring earlier this year an additional seven percent working interest in Shenandoah.
