Abstract
A. F.O. lnderi No. 1 Well was located in the Bowen Basin, Queensland, approximately 15 1/2 miles north-west of Holleston. The well was drilled by Hichter Bawden Drilling Pty Ltd, under contract to Mines Administration Pty Limited, for Associated Freney Oil Fields N.L., to a total depth of 5433 feet. Drilling commenced on 29th June, 1963 and was completed on 11th .\ugust, 1963. A full programme of logging, testing, and coring was undertaken. The well was situated on or near the crest of the lnderi Anticline. Below a thin cover of Quaternary alluvium and Tertiary volcanic rocks the well penetrated Permian sediments from 92 feet to total depth. Economic basement was encountered at 5368 feet and the well was abandoned at 5433 feet in dominantly granite conglomerate. The Permian sediments included the Bandanna Formation, the Mantuan Productus Beds, "Dry Creek Shale", "Early Storms Sandstone", lngelara Formation, Aldebaran Sandstone, Cattle Creek Formation, and the Stanleigh Formation. The objective of the well was to test the hydrocarbon potential of the sediments in the lnderi Anticline, and to establish the section present in the area. Seismic evidence indicated a closure of 600 feet over an area of 15 square miles for the lnderi anticline itself, but closure is increased to 1000 feet over 45 square miles by upthrow against the Albinia Fault to the east. Eight open-hole formation tests were carried out. A gas flow of 800 Md/ D was recorded from the interval 1818 to 1901 feet (DST No. 4). Four of the tests yielded hydrocarbons. Three of these (DST' s Nos 1, 3, and 4) tested the same topmost sand of the Aldebaran Sandstone, and the fourth tested the inteval 3814 to 3944 feet (DST No. 7). Traces of cutting fluorescence were recorded from the Aldebaran Sandstone between 2140 and 2480 feet and live oil was found along a bedding plane in a fairly tight sandstone from Core No. 8 (2456 to 2466 feet). However, DST 1'0. 5, over the interval 23:32 to 2466 feet, produced fresh water only. No other flow was recorded and the well was plugged and abandoned. The stratigraphic drilling operation at A.FO. lnderi No. I was subsidized Under the Petroleum Search Subsidy Act 1959-1961, from surface to total depth.
