Anadarko discovers 'significant' natural gas with Barquentine offshore Mozambique

By Phaedra Friend Troy

Anadarko Petroleum Corp. (NYSE:APC) has discovered more than 416 net feet of natural gas pay at its Barquentine exploration well offshore Mozambique.

Located in Offshore Area 1 of the Rovuma Basin, the Barquentine discovery well transected 308 net feet of pay in two Oligocene sands, which are separate and distrinct features. The discovery is age-equivalent to Anadarko’s previous deepwater discovery offshore Mozambique, Windjammer.

The Barquentine discovery well also encountered an additional 108 net feet of natural gas pay in the Paleocene sands. This deeper pay appears to be part of the same accumulation as the 75 net feet of pay discovered at Windjammer, which is just 2 miles to the southwest.

"With the Windjammer, and now Barquentine discoveries, we have identified a substantial natural gas resource and proven that two distinct trap styles are working in this region of the Rovuma Basin, which is very positive for our ongoing exploration program," Anadarko Sr. Vice President, Worldwide Exploration Bob Daniels said. "Based on the high-quality resource and sands encountered to date in both the Barquentine and Windjammer exploration wells, we have begun designing an appraisal program that will better delineate the areal extent of this large accumulation." 

Anadarko is eager to begin evaluating development options for commercializing the discoveries.

Cove Energy, a project partner on the block, revealed that the partnership believes that “the Windjammer/Barquentine discoveries have found a substantial multi trillion cubic feet natural gas resource.”

Drilled by the Bredford Dolphin drillship to a total depth of 16,880 feet, the Barquentine discovery well is situated in waters measuring 5,200 feet deep.

Once drilling operations are complete at Barquentine, the partnership plans to move the rig 16 miles south to drill the Lagosta exploration well, which is also located on the Offshore Area 1 block.

Anadarko holds more than 2.6 million acres in the Rovuma Basin and has identified more than 50 prospects and leads.

As operator of Offshore Area 1, Anadarko holds 36.5 percent interest in the block. Project partners include Mitsui with 20 percent, BPRL Ventures with 10 percent, Videocon with 10 percent and Cove Energy with 8.5 percent interest. Empresa Nacional de Hidrocarbonetos holds a 15 percent carried interest through the exploration phase. 

The partnership also discovered oil on the block with its Ironclad-1 exploration well.
