Arcadia Anticline Seismic Survey Queensland, 1959 By Associated Australian Oilfields NL  

Authors / CoAuthors

Abstract

A reflection seismic survey was conducted in 1959 on Authority to Prospect 55P by Austral Geo Prospectors Pty Ltd for Associated Australian Oilfields N.L. (A.A.O.), through A.A.O.'s management affiliate, Mines Administration Pty Ltd. The survey was made in the vicinity of the Arcadia Anticline, about 90 miles north of Roma, Queensland. Two exploratory bores had been drilled on the Arcadia Anticline, the first by Oil Search Ltd in 1936, and the second by Associated Australian Oilfields N.L. in 1957. The Oil Search test yielded a gasflow, mainly of carbon dioxide, of 3,000,000 cu.ft per day from the Staircase Sandstone. Shows of oil and gas encountered in the Associated Australian Oilfields bore were insignificant. The purposes of the seismic survey were as follows:- (1) To outline subsurface structural conditions; (2) To indicate whether a more detailed reflection seismic survey might locate drilling sites more favourable for the accumulation of oil or gas than those of the O.S.L. No.3 and A.A.O. No.7 Bores. The three horizons that were mapped showed a general conformity of structure but the maps showing the intervals between the mapping horizons indicated a lack of conformity in thickness of the strata. These results led to the conclusion that the Arcadia Anticline is a fold of recent geological age. The seismic data indicated that the Oil Search No. 3 Bore was drilled on the crest of the Arcadia Anticline. Additional seismic work would be necessary to determine the most favourable location for further investigation.
