Culgoora 2 Corehole
Objective:
The Culgoora 2 corehole is located approximately 22 km west from the township of Narrabri in northern region of PEL 238. The well is designed to appraise the coal seam gas characteristics of the Late Permian Black Jack and Early Permian Maules Creek formation coals approximately 8.2 km to the northwest of the Tintsfield pilot.
Well Status/Results:
The Culgoora 2 drilling operations recommenced on the 8 January after the well was suspended over the Christmas/New Year period with a temporary cement plug set in the 4 ½” casing. The well was drilled to a total depth of 1011m. From wireline logs run at total depth the well is interpreted to have intersected 13.3m of net coal in the Black Jack Formation and 1.3m in the Maules Creek Formation.
