AWE Petroleum Pty Ltd commenced flow testing on the Waitsia 4 gas appraisal well in L01, located in the Perth Basin, on 20 November 2017.Â  Initially well clean-up operations were undertaken, begoe gas flows commenced from a 50 m interval within the Kingia Sandstone.Â  AWE reported that instantaneous maximum flows of 90 MMcf/d, the highest so far observed from Waitsia wells, occurred. Average flows of 89.6 MMcf/d continued, through a 96/64â choke at 2,395 psi pressure. The well has now been shut-in to allow pressure build up surveys to take place before a series of further flow tests.Â   The test at Waitsia 4 is being conducted over the 3,370 â 3,420 m interval within the Kingia Sandstone, which was perforated prior to testing.Â  The strong initial flow rates indicate excellent reservoir quality.Â  The test is the final one in this appraisal phase, which also saw Waitsia 2 and Waitsia 3 tested. AWE reported that this is the final well test prior to Final Investment Decision (FID) for Phase 2 of production from Waitsia.Â  The full testing programme was designed to evaluate reservoir flow potential in the southern extent of the field.Â
