Origin Energy Completes Third Halladale Well

Origin Energy reports that the Halladale-1 DW-3 well has reached a total depth of 1969m MDRT (measured depth below the rotary table). Halladale-1 DW-3 encountered water-bearing sandstones in the Waarre Formation as expected. Following the acquisition of wireline pressure data, the well is in the process of being plugged and abandoned as planned.

The well is located in offshore exploration permit VIC/P37(v) approximately 4 km from shore and 24 km west of the coastal township of Port Campbell.

Halladale-1 DW-3 is the third well drilled from this location. The well has been sidetracked from the Halladale-1 DW-2 well bore and has been drilled to further delineate the down-flank extent of the Halladale gas accumulation discovered by the Halladale-1 DW-2 exploration well.

Results of Halladale-1 DW-3 are in line with expectation based on the results of Halladale-1 DW-2 and the position of Halladale-1 DW-3 on the Halladale prospect.

The wells are being drilled using the Ocean Patriot semisub, with drilling operations managed by Woodside Energy Ltd under an agreement with Origin Energy.

Participants in Halladale-1 DW-3 are Origin Energy as operator with 37.5% and Woodside with 62.5%.
