AWE's Senecio-3 Gas Well in Perth Basin Confirms Commercial Potential of Waitsia Field
Australia based AWE Ltd on Monday said flow test at the Senecio-3 well, in the onshore Perth Basin, Western Australia has confirmed commercial potential of Waitsia field.
“A preliminary maximum gas flow rate of 18.5 million standard cubic feet per day (mmscf/d) was measured on a 48/64 inch choke. At the end of an 18 hour clean up period, the well flowed gas at an average rate of 12.3 mmscf/d with a well head pressure of 1,980 psig over a 5 hour period on a 36/64 inch choke,” AWE said in a statement.
The second stage of the testing program commenced on March 8 and is focused on the primary target in the upper Kingia Sandstone.
The Managing Director of AWE Limited, Bruce Clement, said that the initial flow test results from the primary Kingia target confirmed the commercial potential of the recently discovered Waitsia gas field.
“This is an excellent result for AWE, the local community and Western Australia. The initial flow test results confirm the Kingia Sandstone is a conventional gas reservoir capable of producing commercial flow rates of gas. It has also confirmed the potential for an exciting new gas play in the North Perth Basin,” he said.
The Waitsia gas field represents an estimated gross 2C Contingent Resource of 290 billion cubic feet (Bcf) of gas with significant upside of up to 1.17 trillion cubic feet (Tcf) of gas, Clement added.
“We are planning to drill two additional appraisal wells on the Waitsia field this year to better define its full potential,” he stated.
AWE estimates that the Kingia and High Cliff Sandstone intervals in the Waitsia gas field have gross Contingent Resources in the range from 65 billion cubic feet (Bcf) to 1,170 Bcf, with a best estimate (2C) of 290 Bcf. The Dongara/Wagina formation is estimated to contain an additional 70 Bcf gross 2C Contingent Resource.
Further appraisal of the Waitsia field is planned for late May with the drilling of the Waitsia-1 well, 3km to the east of Senecio-3 in L1/L2.
AWE Limited is the operator of the L1/L2 joint venture and hold 50 percent stake while Origin Energy owns the remaining 50 percent.
