A.A.O. Combarngo No. 1 Well was drilled by Associated Australian Oilfields N.L. on a broad seismic "high" at Combarngo, approximately 30 miles south-east of Roma, Queensland. Drilling was commenced on 5th May, 1961, and was completed on 10th June, 1961, at a total depth of 5985 feet. The drilling contractor was Mines Administration Pty Limited, and the rig used was a National Ideal 55. A full programme of logging, testing, and coring was undertaken. The well penetrated Mesozoic sediments to 5315 feet, Permian sediments from 5315 to 5628 feet, and a volcanic section of unknown age from 5628 feet to total depth. Significant, though small, quantities of a high gravity oil were produced with saline water from the basal Mesozoic sands. Four barrels of 52 degree API gravity oil were recovered in a drill stem test on the Showground Sandstone. Five formation tests were run, the results of which are summarized in Appendix 7. After testing, the well was plugged and abandoned; it was subsequently developed as a water bore producing from the Blythesdale Formation.
