Abstract

Union-Kern-A.O.G. Middle Creek No. 1 was the fourth wildcat well drilled by Union Oil Development Corporation in the south-eastern part of the Surat Basin. The well, located approximately eight miles north-north-east of Union-Kern-A.O.G. Moonie No. 1, was drilled by Mines Administration Pty Limited for Union Oil Development Corporation to a total depth of 6126 feet. Drilling commenced on 19th May, 1962 and was completed on 8th June, 1962. A full programme of logging, testing, and coring was undertaken. The well penetrated 118 feet of Quaternary-Tertiary sandstone and shale; 2153 feet of Lower Cretaceous Roma Formation; 1053 feet of Lower Cretaceous-Jurassic Blythesdale Formation; 1045 feet of Jurassic Walloon Formation; 639 feet of Hutton Sandstone; 540 feet of Evergreen Shale; and 352 feet of Jurassic-Triassic Precipice Sandstone. Below the unconformity at the base of the Precipice Sandstone at 5912 feet, the test entered volcanic conglomerates and siliceous sandstones of the Permo-Carboniferous Kuttung Formation in which the well bottomed at 6126 feet. No drill stem test was carried out in tile Precipice Sandstone but high resistivity on the electric log suggests freshwater saturation. A 60-minute open hole formation test was made of a sandstone interval (5240-5263 feet) witilin the Evergreen Shale. A net rise of 4790 feet of slightly gassy water (37 gr;/gal.) was recovered on the test. In the absence of any significant shows, cement plugs were set and the well was abandoned on 10til June, 1962. The test drilling operation at Union-Kern-A.O.G. Middle Creek No. 1 was subsidized under tile Petroleum Search Subsidy Act 1959-1961, from surface to total depth.
