Abstract

Southwest Bairnsdale No. 1 Well was located about 15 miles west-south-west of Bairnsdale, in the Gippsland Basin of Victoria. The well was drilled by Reading and Bates (Australia) pty Ltd for Woodside (Lakes Entrance) Oil Company No Liability and Arco Limited, to total depth of 3926 feet. Drilling commenced on 8th January, 1963 and was completed on 14th February, 1963. A full programme of coring and logging was undertaken. The objectives of the drilling operation were to obtain stratigraphic data, and to test the hydrocarbon potential of the pre-Tertiary sediments by a well favourably situated to intersect pinch-out zones in the expected Upper Devonian-Lower Carboniferous sequence occurring below a thin Tertiary cover. The well achieved its objectives; Tertiary sediments were penetrated from surface to 1408 feet, Lower Carboniferous-Upper Davonian non-marine sediments to 3806 feet, and pre-Upper Devonian biotite granite to total depth at 3926 feet. Middle Devonian marine sediments, which are exposed in the highlands 25 miles north of the well, were not encountered. Basal Tertiary gravels, although having good porosity and permeability, contained only freshwater. The Lower Carboniferous-Upper Devonian sandstones are well cemented and have very little porosity or permeability. No shows of hydrocarbons were found in the well. One formation test was made over the interval 2522 to 2559 feet after a small quantity of gas was recorded by the gas detector. The test recovered only 120 feet of drilling mud anl;i the flowing pressures recorded were very low. The well was later plugged and abandoned as a dry hole. The off-structure drilling operation at SouthwestBairnsdale No. 1 was subsidized under the Petroleum search Subsidy Act 1959-1961, from surface to total depth.
