The Warrego Energy (ASX:WGO) and Strike Energy Limited JV has obtained significant final results of the flow testing activities at WE3 from the West Erregulla gas field in the onshore Perth Basin in Western Australia.
The testing programme at the WE3 location from the 40m of perforations across the Kingia Sandstone reservoir from 4,733m (measured depth) has now been completed with the well performed strongly during the seven-day multi-rate test with high flowing well head pressures throughout the programme.
The well remained very stable for the five-hour high-rate test which was constrained by well testing equipment and was recorded at 83 mmscf/d with a flowing well head pressure of 3,474 psi on a 68/64” choke.
Once the test was completed the well was shut in for a pressure build up. After only three-hours the WE3 well head pressure had already returned to near virgin reservoir pressure which is indicative of both the quality of the reservoir and the presence of a substantial connected gas volume beyond the well bore.
Preliminary interpretation of these results underpins the deliverability of the Reserves booked across the North of the field in Netherland Sewell and Associates Inc recent field wide Reserves upgrade as released to the market on 27th July 2022 “West Erregulla Reserves upgraded by 41%.
Throughout the test no sand or formation water production was observed, and the gas remained a low impurity dry gas, which is in line with gas compositions from the field and the region.
Once the down hole gauges have been retrieved the testing equipment will be demobilised from the WE3 well site.
Strike Energy Limited is operator and the holder of a 50% joint venture interest in EP469, and Warrego Energy (ASX: WGO) a holder of the other 50% joint venture interest.
