Union-Kern-A.O.G. Wandoan No. 1 was the first wildcat drilled by Union Oil Development Corporation in the north-eastern part of the Surat Basin. Union-Kern-A.O.G. Moonie No. 1 had proven the potential of the Jurassic-Triassic Precipice Sandstone as an oil reservoir and it was necessary to evaluate this reservoir in other parts of the basin. In the Wandoan area seismic surveys defined a large north-plunging anticline in rocks of the Bowen Group (Triassic-Permian), with a domal closure in the Great Artesian Group superimposed on the north plunge of the feature. This domal closure shows more than 200 feet of vertical closure encompassing an area of 30 square miles. Wandoan No. 1 Well, located approximately 73 miles east-north-east of Roma, was drilled by Oil Drilling and Exploration Limited for Union Oil Development Corporation to a total depth of 10,736 feet. Drilling commenced on 22nd April, 1962 and was completed on 18th June, 1962. A full programme of logging, testing and coring was undertaken. The well penetrated 4798 feet of Mesozoic sediments of the Great Artesian Group, 4468 feet of tuffaceous shale, siltstone and sandstone of the Triassic Cabawin Formation of the Bowen Group and bottomed at 10,736 feet in the Lower Triassic-Upper Permian Kianga Formation. Wandoan No. 1 was drilled primarily to test the petroleum potential of the Precipice Sandstone. The test was continued for stratigraphic information through the Cabawin Formation into the Kianga Formation. A 60-minute open hole formation test was run over the interval 3260 to 3278 feet near the top of the main porous sandstone of the Precipice Sandstone. A net rise of 2830 feet of fresh water (10 gr./gal.) was recovered in the test. A subsequent analysis indicated traces of hydrocarbons in the formation water. Another 60-minute open hole formation test over the interval 6024 to 6095 feet in the upper part of the Cabawin Formation yielded a net rise of 105 feet of slightly gassy watery mud. The stratigraphic drilling operation at Union-Kern-A.O.G. Wandoan No. 1 was subsidized under the Petroleum Search Subsidy Act 1959-1961, from surface to total depth.
