Abstract

Bonaparte No. 1 Well, located approximately 52 miles north-east of Wyndham, in the Bonaparte Gulf Basin of Western Australia, was drilled by Reading and Bates (Australia) Pty Ltd for Alliance Oil Development Australia No Liability to total depth of 10,530 feet. Drilling commenced on 18th July, 1963, was suspended at 10,283 feet on 19th December, 1963, resumed on 25th April, 1964, and was completed on 4th June, 1964. A full programme of logging, coring, and testing was undertaken. The well penetrated the Upper Carboniferous Point Spring Sandstone from surface to 638 feet; the Lower Carboniferous Tanmurra Formation to 1630 feet, and Milligans Beds to 7480 feet; the Lower Carboniferous to Upper Devonian Burt Range Formation Equivalent to 9492 feet; and the Upper Devonian Cockatoo Sandstone Equivalent to 10,530 feet, total depth. An angular unconformity occurred at the base of the Milligans Beds. Of the twenty drillstem tests conducted during the drilling operation, three yielded fresh water from the Tanmurra Formation, and one yielded gas-cut salt water from the interval 5627 to 5696 feet in the Milligans Beds. Four tests were misruns, and twelve obtained no recovery other than drilling fluid. The well was plugged and abandoned as a dry hole on 6th June, 1964. The stratigraphic drilling operation at Bonaparte No. 1 Well was subsidized under the Petroleum Search Subsidy Act 1959-1961, from surface to total depth.
