Energy Resources Ltd. in the onshore North Perth basin of Western Australia has flowed gas in a preliminary test of its Lockyer Deep-1 prospect that straddled permits EP368 and EP 426.
Following perforating operations in a 25 m section of Kingia sandstone at 4,041-4,067 m, a strong continuous dry gas flow was achieved from the well through a 36/64-in. choke, partner Norwest Energy Ltd. said. Stable flowing wellhead pressure was over 4,800 psi.
Gas samples were obtained before the well was shut in with wellhead pressure of 5,122 psi.
Onsite gas sampling indicates the presence of 4-4.5% CO2 and 1-2 ppm hydrogen sulphide. Samples have been sent for independent verification and full compositional analysis.
The JV plans to run a full production test of the Kingia section when equipment arrives on site commencing in about 10 days.
Given the rapid clean-up followed by early strong flow rates, the JV anticipates the Kingia reservoir at Lockyer Deep is of good quality with potentially high gas deliverability.
If successful flows are obtained from a production test, the well will be suspended for future completion as a gas producer.
Energy Resources is operator with 80% interest. Norwest holds the remaining 20%.
