This mouse pad was created by the Mineral Exploration Promotion section as an informative give-away for domestic and international conferences. The mouse pad displays an abbreviated periodic table of the elements with those elements that Australia produces, has known resources of and explores for highlighted in different colours.

Introduction Australia has a thriving oil and gas industry with expanding infrastructure and many exploration opportunities. Geologically the country has the potential for large oil and gas discoveries within extensive sedimentary basins. Australia is also one of the world leaders in providing open-file geological data at a low cost, and an open Acreage Release process with competitive taxation regimes. Politically, Australia is very stable with a very high standard of living and a long-standing democratic culture based on the rights of the individual and the rule of the law. There is a free market philosophy which welcomes foreign investment - Australia has no mandatory local equity requirements and has no government owned oil companies. Government facilitation of investment includes fast-tracking of approvals processes for major projects. This CD provides some basic Australian data including: Oil and Gas Resources of Australia 2002 The Oil and Gas Resources of Australia 2002 (link to Pdf ) publication is the definitive reference on exploration, development and production of Australia's petroleum resources. It covers exploration, reserves, undiscovered resources,development, coal-bed methane resources, production, crude oil and shale oil and supporting information and statistics. An estimate of Australia's undiscovered oil and gas potential and a review of geological sequestration of carbon dioxide in Australia is also included.

This publication combines the completion reports of two wells drilled at Port Campbell in the Otway Basin, Victoria, by Frome-Broken Hill Company Proprietary Limited in 1959 and 1960. Port Campbell No. 1 was located near the crest of a seismic "high". The seismic reflection survey showed that there was an increase in thickness of section down dip to the south-east; Port Campbell No. 2 Well was sited about 1-3/4 miles south-east of Port Campbell No. 1. Port Campbell No. 1 Well was spudded in on 9th September, 1959, and reached a total depth of 5965 feet inparalic sediments of Lower Cretaceous age on 9th December, 1959. Miocene and Oligocene marl and calcareous clay were penetrated to 1375 feet, then more than 3000 feet of Lower Tertiary, Eocene and (?)Palaeocene,and 1000 feet of Cretaceous sediments. The only break evident in the succession in Port Campbell No. 1 was at 5656 feet where a lithological change was noted together with a conspicuous break on the electric log. At this depth the well intersected a porous horizon which produced a flow of petroliferous gas. Drilling commenced at Port Campbell No. 2 on 12th July, 196q and was completed on 1st December, 1960, at 8846 feet in sediments of the Otway Group. 1214 feet of Upper Tertiary (Miocene and Oligocene) and approximately 3800 feet of Lower Tertiary (Eocene and Palaeocene) sediments were intersected. Time boundaries are still indefinite but at least 2700 feet of Cretaceous sediments are thought to be present in the well. Two unconformities were deduced: the upper at 7910 feet, between the Waarre Formation and the Belfast Mudstone, corresponds to the break at 5656 feet in Port Campbell No. 1, but represents a hiatus smaller than that in the earlier well as an extra 770 feet (approximately) of basal Belfast Mudstone and topmost Waarre Formation are present in Port Campbell No. 2.* The lower unconformity separates the Waarre Formation and the Otway Group on a horizon lower. than was reached in Port Campbell No. 1, but it was not well defined by the information derived from the one hole. The petroliferous gas, and a small amount of condensate, produced in Port Campbell No. 1 was a strong but not commercial flow and came from a coarse quartz sandstone between 5656 and 5668 feet. On test, flow rate and pressure decreased rather rapidly and recovery, on standing, was practically imperceptible, indicating that the reservoir is small and not connected with any larger reservoir. Port Campbell No. 2 did not show any evidence of free gas or oil. The gas obtained from testing was only minor and derived from solution in formation water.

A.O.G. Wentworth No. 1 Well was located in the Murray Basin, approximately 20 miles north of Wentworth, New South Wales. The well was drilled by W.L. Sides and Son Pty Limited for Australian Oil and Gas Corporation Limited to a total depth of 2081 feet. Drilling commenced on 8th September, 1961, and was completed on 14th October, 1961. A programme of coring and electric logging using a Widco unit was carried out, but no perforating, squeeze cementing, or testing operations were undertaken. The well was drilled to determine the nature of the sediments immediately beneath the Tertiary sequence, with particular reference to a refractor at a calculated depth of 1650 feet. This was thought to be basement before drilling started, but it was not identified during logging. The well penetrated 192 feet of Quaternary sands and grits; 1081 feet of Tertiary sands, silts, clays, marls, and limestones; 331 feet of Lower Cretaceous sediments, including Roma Formation Equivalents; 451 feet of Permian sandy mudstones; and bottomed in conglomerate of possible Permian age. No shows of hydrocarbons were observed during the drilling operation. In the New South Wales part of the Murray Basin, Lower Cretaceous sediments had not been previously recorded, and Permian sedimentation had been recorded in only one area, between Oaklands and Coorabin, some 250 miles east of Wentworth No. 1 Well. The off-structure drilling operation at A.O.G. Wentworth No. 1, New South Wales, was subsidized under the Petroleum Search Subsidy Act I!lS!l, from surface to total depth.

Jurien No. 1 Well was located on the western margin of the Perth Basin, Western Australia, approximately 76 miles south-south-east of Geraldton. The well was drilled by Oil Drilling and Exploration (W.A.) Fty Limited for West Australian Petroleum Fty Limited, to a total depth of 3366 feet. Drilling commenced on 9th July, 1962, and was completed on 21st August, 1962. A full programme of logging, testing, and coring was undertaken. The well was spudded in the Coastal Limestone of Pleistocene age, and penetrated 811 feet of Lower Triassic Kockatea Shale; 2274 feet of Permian (Artinskian) sediments; 35 feet of (1) Permian sandstone, and entered Precambrian granitic gneiss at 3208 feet. The well was drilled to investigate the stratigraphy and petroleum potential of the Permian sediments in the Jurien Anticline. At least 200 feet of structural closure over eight square miles were proved for that area on the basement refractor. The main objectives were the sandstones in the Irwin River Coal Measures and High Cliff Sandstone. No potential reservoir beds were observed and only the Lower Triassic Kockatea Shale appeared to be a good source rock for hydrocarbons although minor oil traces were observed in some of the Permian section. Three drillstem tests were carried out over the intervals 552 to 595 feet, 1940 to 2020 feet, and 2196 to 2356 feet. No water, oil, or gas was recovered in any of the tests. The stratigraIilic drilling operation at Jurien No. 1 was subsidized under the Petroleum Search Subsidy Act 1959-1961, from surface to total depth.
