South Erregulla-1: Striking South to Extend the Perth Basin Permian Gas Play
Strike Energy (100%) has reported a discovery at South Erregulla in February 2022. The well was drilled with the Ensign 30 rig to a TD of 4,900m in the Block EP503. The firm reported two gas intervals in the Wagina sands (16m good quality pay and 61m net gasifier with lower poroperm) and Kingia sands (14m). The discovery is analogous to the results of the Beharra Springs, Red Back and Tarantula wells only ~14km to the west, where high flow rates are recorded. The well is being completed for testing. The North Perth Basin has provided several gas discoveries in recent years, with conventional gas fields being revealed east of the Mountain Bridge Fault. To the north, with partner Warrego, Strike is developing the West Erregulla gas discovery. The latter field has proven up to 400 Bcf gas, while Strike is chasing up to 1.6Tcf resources over this Permian play in licence EP503. Another recent discovery was chalked up at Lockyer Deep (MinRes and Norwest), while Beach and Mitsui had success at Waitsia. Further development work is expected, with Strike considering both conventional and innovative projects including a major urea processing plant (Project Haber) which could lead on to hydrogen and ammonia production, a significant growth sector for energy in Australia.
