Vintage Energy Ltd., Adelaide, has completed its initial test of the Odin-1 gas discovery in the Cooper basin of northeast South Australia with a flow rate of 6.5 MMcfd.
Well head pressure was 1,823 psi measured through a 28/64-in. choke. Water (interpreted as water from condensation) flowed at 38 b/d.
Vintage began the test Oct. 27 with a 36/64-in. choke, measuring a flow of 10.3 MMcfd at a wellhead pressure of 1,666 psi before changing to the smaller choke size after 25 hours.
Infield measurements estimated the raw gas was made up of 78% hydrocarbons and 22% of inerts.
The test confirms potential of Permian Epsilon and Toolachee formations, Vintage said.
The well has been shut in for 10 days to allow pressure build. A production logging tool will be run to gather information on contributions of the various zones to flow rate, which will help determine reservoir and production characteristics and guide design of appraisal and future development programs.
Odin-1 is in retention lease PRL 211 about 6 km west of the company’s Vali gas field across the state border in Queensland.
Vintage is operator with 42.5%. Metgasco Ltd. and Bridgeport (Cooper Basin) Pty Ltd. each hold 21.25%. Impress (Cooper Basin) Pty Ltd. holds 15%.
