Abstract

The Innamincka No. 1 test well, drilled by Delhi Australian Petroleum Ltd, Frome Broken Hill Company Pty Ltd, and Santos Limited, in the north-east corner of South Australia, penetrated the strata below the surface in the deeper portion of the Great Australian Artesian Basin to a total depth of 12,637 feet. The test was begun late in March, 1959, using a National 130 drilling rig operated by Delta Drilling Company. The operation, under supervision of drilling, engineering, and geological personnel of Delhi Australian Petroleum Ltd, involved an extensiveprogranune to obtain technical data relative to the occurrence of hydrocarbons in the strata cut by the drill bit, as well as stratigraphical information concerning the geological history of the area. Included in the operation was a full complement of logging, coring, and testing programmes provided and conducted by the operating Company and their Contractors. Innamincka No. 1 established the presence of at least 6,723 feet of Mesozoic sediments, as well as 5,914 feet of sediments of Palaeozoic age at the wellsite. Several minor showings of hydrocarbons were encountered within the Mesozoic sequence below 3,928 feet in nonmarine sediments; however, after thorough examination and testing, the shows proved inconsequential. Several zones within the interval 4,390 feet to 7,050 feet evidenced physical qualities such that the rock could be classified as mechanically favourable as reservoir type rock, but an analysis of the sediments suggested that their origin was not favourable as hydrocarbon source rocks. The intervals 0 feet to 4,390 feet and 7,050 feet to 12,637 feet did not suggest qualities of either source-bed or reservoir type rocks. The well was completed in late November, 1959 as an artesian water well from the Blythesdale Formation through perforations between 4,390 feet to 4,560 feet.
