North West Shelf
The North West Shelf is a continental shelf region of Western Australia. It includes an extensive oil and gas region off the North West Australia coast in the Pilbara region. Geology. Considerable parts of the region are the highest prospective gas and oil areas of Australia. The main sedimentary basin providing the opportunity is the Northern Carnarvon Basin - however it is only one part of the regional complex. Oil and gas. It has a considerable number of oil and gas wells, pipelines, production areas and support facilities. Location. As an area it is located in the Indian  Ocean between North West Cape and Dampier. Dampier is usually considered the main administrative locality for the shelf. Production areas. The production areas are located offshore and within the jurisdiction of the Western Australian state government. The two main production areas are the Thevenard Production Area close to Onslow, and the Varanus Production Area west of Dampier. Oil fields. The North West Shelf oil extraction is negligible compared to the volume of gas produced. Gas project. The North West Shelf Venture is a project to extract resources within the region from various gas fields - however it is considered to be  only in part of the whole shelf region. It involves developments on the Burrup Peninsula, Barrow Island and other locations.
