South Australia strat traps yielding wet gas

By OGJ editors
HOUSTON, May 5 -- Drillsearch Energy Ltd., Sydney, launched an extended production test of the 2008 Brownlow wet gas discovery and plans to similarly test the Canunda wet gas discovery 11 km north of Brownlow in the Cooper basin of South Australia.

After a period at 10 MMcfd with 120 b/d of condensate on a 24/64-in. choke, the choke was opened to 1 in. for a rate of 18 MMcfd from Permian mid-Patchawarra.

The well is in PEL 106, 2 km north of the Middleton wet gas discovery, and 55 km northwest of Moomba, where the condensate will be shipped.

Drillsearch said Brownlow has the potential to be a large stratigraphic trap with three-way dip closure. Beach Energy Ltd., operator of the PEL 106 farmin block with 50% interest, drilled Brownlow as part of farmout obligations now fulfilled.

Drillsearch and Beach hold a large position in a western flank wet gas fairway and have indentified more than 20 prospects on stratigraphic traps that represent a combined best case prospective resource of as much as 200 bcf of sales gas and 8 million bbl of condensate. They plan more drilling as soon as flooding subsides and weather permits.
