Abstract
Babrongan No. 1 Well was located on the southern edge of the Jurgurra Terrace, 97 miles east-south-east of Broome, Western Australia, and approximately 11 miles south of Frome Rocks No. 2. The well was drilled by Oil Drilling and Exploration (W.A.) Pty Limited for West Australian Petroleum Pty Limited, to a total depth of 6395 feet. Drilling commenced on 29th May, 1962, and was completed on 10th July, 1962. A full programme of logging, testing, and coring was undertaken. The well penetrated 20 feet of Quaternary surface sand and clay, 230 feet of undifferentiated Mesozoic sandstone and siltstone, and 6135 feet of Palaeozoic sandstone, siltstone, shale and minor carbonate. The Palaeozoic formations or units encountered were the Poole Sandstone and Grant Formation of Permian age and the Luluigui Formation, Clanmeyer Siltstone,and an un-named unit of the Upper Devonian. At 2340 feet the well intersected a fault and/or unconformity. If a fault is present it is believed to have a throw of approximately 3000 feet. With the exception of approximately 145 feet, the Luluigui Formation has been removed. Correlation with Frome Rocks No. 2 Well shows that an additional 2572 feet of Clanmeyer type sediments are present in Babrongan No. 1. The un-named unit of the Upper Devonian has been equated to the Virgin Hills Formation. This is the first time that this formation has been suspected of being present on the Jurgurra Terrace. The presence of these sediments is considered important to further exploration in the area as the Virgin Hills Formation is associated with reef development on the north rim of the Canning Basin and may also indicate the presence of reefs on the Jurgurra Terrace. Two minor shows of hydrocarbons were noted in the well. Neither was considered to be of commercial value and no drill stem tests were run. The well was abandoned at 6395 feet because of mechanical difficulties. The stratigraphic drilling operation at Babrongan No. 1was subsidized under the Petroleum Search Subsidy Act 1959-1961, from surface to total depth.
