DEEP-WATER GIPPSLAND A New Frontier • Deep water structures revealed by contemporary seismic and high resolution aeromagnetics • Gippsland petroleum systems extend into new acreage • Potential play-fairways identified PESA News April/May 2000 VICTORIAN SUPPLEMENT MINISTER’S STATEMENT VICTORIAN SUPPLEMENT he discovery of Australia's first giant petroleum fields in Bass Strait in the 1960's had a profound effect on both the Victorian and national economies. Major petrochemical industries and many other manufacturing and Tprofessional businesses are located in the State, largely because of the proximity to the oil and gas reserves in offshore Gippsland. As major a population and infrastructure base, the State provides employees and support for these companies as well as markets for their products. The Australian corporate headquarters of Exxon-Mobil, BP-Amoco and Shell are all located in Melbourne, as well as smaller active oil companies. Victoria is well served by its growing gas infrastructure. With coal fired electricity, the state has benefited from an abundance of energy sources, providing the most competitive energy pricing to business and domestic consumers in the nation. The value of the resource extracted from the basins within Victoria and its Adjacent Area offshore exceeds $3 Billion per year. Although the State realises only a small portion of direct revenue from royalties, it is in the indirect benefit of having a local supply of oil and gas providing the ongoing relatively inexpensive energy that adds so much value to the State. The Brack's Government was elected in 1999 with a mandate to increase energy supply security in the wake of the Longford tragedy in 1998. The Essential Services Commission will be established to address supply security for essential services including gas, electricity, water and public transport. Intra- and Inter-state gas supply through the existing and future gas projects will not only augment supply security to Victoria and the adjacent states but is stimulating exploration interest. Victoria will also encourage the broadening of the gas supply base through providing information to attract and assist responsible exploration and interconnection with Victorian and interstate basins. This encouragement of oil and gas exploration is the prime focus of this publication. As well as providing information relating to future releases of acreage under consideration, it provides a summary of activities relevant to the Petroleum sector by my Department and some of the companies already active in the area. I believe that both existing and future investors will be informed and retain it for future use.
