Eneabba No. 1 Well was located in the northern part of the Perth Basin, Western Australia, approximately 32 miles south-east of Dongara. The well was drilled by Oil Drilling and Exploration (W.A.) Pty Limited for West Australian Petroleum Pty Limited, to a total depth of 13,712 feet. Drilling commenced on 12th June, 1961 and was completed on 25th November, 1961. A full programme of logging and coring was undertaken. After drilling through 28 feet of Quaternary alluvium, the well penetrated 5558 feet of Lower Cretaceous to Middle Jurassic Yarragadee Formation, 276 feet of Middle Jurassic probable Cadda Formation equivalent, 3894 feet of Lower Jurassic to Upper Triassic Cockleshell Gully Formation, 960 feet of Upper Triassic Lesueur Sandstone, 436 feet of Middle to Lower Triassic Woodada Formation, and 2548 feet of Lower Triassic Kockatea Shale. The pipe stuck at 5275 feet when starting to pull out at 13,712 feet, and eventually the well was abandoned leaving 9200 feet of drill string in the hole. The well was drilled to investigate the petroleum potential and stratigraphy of the Mesozoic and Palaeozoic sediments in the northern part of the Perth Basin. The Mesozoic section was much thicker than expected at the well which had not reached the Palaeozoic when abandoned at 13,712 feet because of mechanical difficulties. Many oil shows and one strong gas show (from a fracture zone between 12,795 and 12,800 feet) were recorded in the Kockatea Shale but no formation tests were carried out because of the impervious nature of the formation. The stratigraphic drilling operation at Eneabba No. 1 was subsidized under the Petroleum Search Subsidy Act 1959, from surface to total depth.
