HOUSTON, Apr. 5 – Beach Energy Ltd., Adelaide, has gauged gas-condensate at promising rates early in extended tests at the Canunda-1 discovery in Australia’s Cooper basin, said 50% partner Drillsearch Energy Ltd., Sydney.
The well is producing 3 MMscfd of gas with a gas-oil ratio of 180 bbls/MMscf on a 22/64-in. choke. Canunda is in South Australia northwest of Moomba.
Initial extended production testing began in mid-2010, and due to high condensate production rates the 10-day test was choked back in view of storage and transportation constraints. Over the 10-day testing period of the upper zone, the Canunda well produced more than 2,500 bbl of 62° gravity condensate.
The new production completion is designed to accommodate the very high liquid content gas. This extended production test is designed to better determine the overall extent and potential reserves and a field development plan.
Drillsearch in December 2010 estimated a contingent resource for Canunda-1 of 2.8 million boe, including 930,000 bbl of condensate and 46,000 tonnes of LPG. Beach has previously declared Canunda commercial and carries it as 2P reserves. Drillsearch is reviewing Canunda for reclassification as reserves as part of joint venture consideration of an overall development plan for PEL 106B.
As part of the PEL 106B pending development, Gaffney Cline & Associates is reviewing the Canunda, Udacha, Brownlow, and Middleton discoveries for reclassification to reserves status as justified for development.
