Abstract
A.A.O. Winnathoola No. I, located approximately 8 miles north-west of A.A.O. Combarngo No. I, and 22 miles south-east of Roma in Queensland, was drilled by Mines Administration Pty Limited for Associated Australian Oilfields N.L., to a total depth of 5342 feet. Drilling commenced on 1st September, 1961 and was completed on 22nd September, 1961. A full programme of logging, testing, and coring was undertaken. The well penetrated 4919 feet of Mesozoic sediments, 207 feet of Permian sediments, and 216 feet of of sediments of (?) Devonian Timbury Hills Formation. Two drillstem tests were carried out. The first tested the interval 4521 to 4465 feet (basal Jurassic sands) for 120 minutes and yielded a flow of gas at the rate of 616 Mcf/D. The second tested the interval 5342 to 5035 feet (base of Permian) and yielded a trace of gas. The stratigraphic drilling operation at A.A.O. Winnathoola No. 1 was subsidized under the Petroleum Search Subsidy Act 1959 for the section below the Jurassic Injune Creek Beds to total depth.
