LOS ANGELES, Oct. 19 -- Anadarko Petroleum Corp. said its Barquentine exploration well in Offshore Area 1 of Mozambique's Rovuma basin encountered a total of more than 416 net ft of natural gas pay in multiple high-quality sands—its second find since August.

“Another gas discovery by Anadarko at Offshore Area 1 highlights the area's potential as well as that of the wider Rovuma basin, which has attracted interest from major players such as ExxonMobil and BG Group,” said analyst BMI.

In a note to investors, Cenkos Securities analysts agreed, saying, “We believe that this additional discovery of deeper gas could yield a further 3 tcf of gross resource to that previously encountered at Windjammer.”

According to Anadarko, the discovery well encountered more than 308 net ft of pay in two Oligocene sands that are separate and distinct geologic features, but age-equivalent to those encountered in Anadarko's previously announced Windjammer discovery.

The firm noted that the well also found an additional 108 net ft of gas pay in the Paleocene sands, saying that this deeper pay appears to be part of the same accumulation as the 75 net ft of pay that was encountered at the Windjammer discovery, located 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,” said Bob Daniels, Anadarko senior vice-president, worldwide exploration.

“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,” Daniels said.
Anadarko said the Barquentine well was drilled to a total depth of 16,880 ft in 5,200 ft of water.

Once operations are complete at Barquentine, the partnership plans to mobilize the Belford Dolphin drillship about 16 miles to the south to drill the Lagosta exploration well, also in Offshore Area 1.

In August, reports said that Anadarko’s exploratory well off Mozambique had penetrated 38 m of net oil and gas saturated sands in the upper of two Cretaceous fan lobes, signaling the first documented occurrence of liquids hydrocarbons in deep water off East Africa (OGJ Online, Aug. 30, 2010).

Anadarko is operator with a 36.5% working interest in Offshore Area 1. Other stakeholders include Mitsui E&P Mozambique Area 1 Ltd. 20%, BPRL Ventures Mozambique BV 10%, Videocon Mozambique Rovuma 1 Ltd. 10%, and Cove Energy Mozambique Rovuma Offshore Ltd. 8.5%. Empresa Nacional de Hidrocarbonetos EP's 15% interest is carried through the exploration phase.
