Strike Energy has spudded South Erregulla1 and was drilling ahead in a 17-1/2” hole in the top section at a measured depth of 1,045m.
Strike said it will drill ahead to 1,945 before running a 13-5/8” casing and cementing and that the well was being drilled with an optimised design to ensure that well conditions are maximised for reservoir preservation and data acquisition when drilling (and coring) through the primary objective in the Kingia Sandstone.
South Erregulla is located in the 100% Strike owned EP503 which adjoins EP469 where Strike, as operator, made a large, high-quality conventional gas discovery at West Erregulla. South Erregulla1 lies less than 5km to the south of the nearest successful West Erregulla intersection.
Strike said that South Erregulla has significant resource potential in the Kingia Sandstones with a high chance of success due to the strong data control over the Erregulla region (wells and seismic), consistent geological outcomes in the Kingia and recent identification of updip connectivity to the known West Erregulla gas field.
The company expects to encounter the Kingia at a revised depth of 4,369m, up to 200m shallower than the penetration of the Kingia at West Erregulla 2. Strike will collect whole core and an advanced series of wireline logs across the Kingia Sandstones ahead of planned flow testing subject to results.
Strike has interpretated a major structural high to the south of West Erregulla and said numerous drilling results at West Erregulla, Waitsia, Beharra, Lockyer and Irwin correlate to a geophysical model which supports the presence of gas-charged porous sands in the Kingia Sandstone at South Erregulla.
Recently corroborated structural mapping by Netherland Sewell and Associates shows the Greater Erregulla structure rising to the South where the South Erregulla target has been identified. Strike said that this interpretation suggests that South Erregulla is connected and updip of West Erregulla (a known conventional gas field) correlating to a likely similar gas accumulation.
“The primary objective of South Erregulla1 and any subsequent appraisal wells is to delineate approximately 350PJs of high confidence resource in order to secure the gas requirements for Project Haber, Strike’s proposed Geraldton based 1.4mtpa urea fertiliser manufacturing facility. On confirmation of success at South Erregulla 1, Strike will look to sanction additional detailed engineering (FEED), finalise the urea offtake, and progress the equity/debt processes for Project Haber,” Strike Energy said.
