The first flow test of an Anadarko Petroleum Corp. well offshore Mozambique has provided “confidence in well designs that are capable of 100-200 MMcfd,” the company said.
Anadarko said the Barquentine-2 well flowed at an equipment-constrained rate of 90-100 MMcfd with minimal pressure drawdown and exceptional flow characteristics.
The test “confirmed the deliverability of this reservoir and indicated a low density of development wells may be sufficient to produce the reservoir,” said Anadarko Senior Vice-President, Worldwide Exploration, Bob Daniels.
"Using preset gauges in an offset well, we were able to confirm connectivity and reservoir continuity over a distance of more than 3 km. The test also proves the reservoir has very high permeability, meeting the quality specifications for the partnership's LNG development plans.
“This is a very encouraging way to start our testing program, which is an important component in the reserve certification process, as we focus on achieving FID (final investment decision) around the end of 2013,” Daniels said.
Barquentine-2 is in 5,400 ft of water in Offshore Area 1 of the Rovuma basin. The drillstem test was conducted by the Deepwater Millennium drillship, which is expected to be mobilized to the Barquentine-1 location for a second flow and interference test in the complex. The 2012 test program also includes drillstem tests in the Lagosta and Camarao areas south of Barquentine.
Anadarko is operator of 2.6-million-acre Offshore Area 1 with a 36.5% working interest. Coowners are 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 EPs 15% interest is carried through the exploration phase.
