The Shenandoah #6 appraisal well hit total depth with the Ocean Blackhawk ultra deepwater drilliship, and encountered wet Wilcox sands.
The well is currently being sidetracked to locate the oil-water contacts. This well, according to Anadarko, is designed to establish the oil-water contact on the eastern flank of the field and further quantify the resource potential.
Anadarko spud the Shendandoah-6 appraisal well in December in Walker Ridge Block 52, on the eastern flank of the field.
Anadarko’s January operations report notes that the FEED engineering on a semisubmersible development concept is ongoing as the company continues appraisal drilling to delineate the opportunity.
Anadarko says that the Shenandoah prospect is emerging as one of the largest discoveries in the company’s history. The Shenandoah-2 appraisal well encountered more than 1000ft of oil pay in multiple high-quality, Lower Tertiary reservoirs. The company is continuing to evaluate this potentially giant find, along with adjacent success at the Yucatan discovery.
Earlier this month, Anadarko revealed plans to spend US$1.1 billion in its deepwater assets, which include the Gulf of Mexico, Algeria, and Ghana. The company’s total initial capital program for 2017 stands at $4.5-$4.7 billion.
Anadarko operates Shenandoah with 33% stake. Its partners on the prospect include Cobalt (20%), and Venari Offshore (17%).
