Vampire 2D Non-Exclusive Seismic Survey

Browse Basin, Australia

The Vampire 2D survey acquired 7,000 km of 2D long-offset seismic in the prolific Browse Basin, Western Australia. The layout was designed with extensive input from industry with respect to line orientation and well-tie selection. The survey will provide an invaluable tool for understanding the regional structural and stratigraphic framework of the Browse Basin.

The survey was completed using the Seabird vessel, Aquila Explorer. The Aquila utilizes high-end Sercel Sentinel Solid Streamer technology and Bolt Source equipment (up to 6300 cu in) and is one of the best equipped 2D seismic vessels available to undertake this project.

The seismic data processing has been undertaken in Perth, Western Australia and provides a consistent regional dataset that also ties the most relevant well information. A full suite of additional products has been generated during the processing sequence and allows further work such as AVO studies, inversion and basin modelling.

The Browse Basin has received intensified exploration in recent years after a sporadic exploration history. Several large gas fields (> 5TCF) has been discovered within the basin and with these discoveries has seen the push to commercialise them via LNG facilities. Outboard potential of this basin has now also been successfully tested.

No comprehensive regional well tie survey has been acquired for at least 10 years in the Browse and tying these new discoveries is a key objective of the Vampire 2D survey.
