AWE Starts Flow Testing Second Zone in Perth Basin's Waitsia-1 Well

AWE Limited has commenced flow testing of the second zone in the Waitsia-1 well, the Kingia Formation, to further appraise the conventional Waitsia gas discovery in the onshore Perth Basin, Western Australia.

The testing program is designed to determine well deliverability from two conventional reservoir zones and to collect gas samples for compositional analysis, AWE said.

The first zone tested, the High Cliff Sandstone, flowed gas at a rate of 24.7 mmscf/d. The second zone being flow tested is the shallower Kingia Formation, where a 15 metre interval (3,333 – 3,348 metres) has been perforated. The well flowed gas at an average rate and pressure of 25.7 mmscf/d.

“This is clearly an outstanding result. Both reservoir intervals tested in Waitsia-1 have each flowed at 25 mmscf/d., The excellent flow rates achieved will enable us to reduce the number of wells, and development costs, to achieve the targeted production rate of 100 mmscf/d for the full field development with the potential to increase the field production rate. Engineering and planning work for the first stage of development is well advanced, with early stage production of approx. 10 mmscf/d planned for mid-2016,” AWE’s Managing Director, Bruce Clement, said.

AWE is the operator of the L1/L2 joint venture with 50 percent stake while Origin Energy has the remaining 50 percent stake.
