Sink your teeth into the Browse Basin with Searcher’s Vampire 2D Seismic Survey. The recently acquired 2D survey comprises of ~7,000 km of ready to interpret long-offset modern PSTM and PSDM seismic data in the prolific Browse Basin, Western Australia. Tied with 60 key wells, the dataset provides an easily accessible regional overview of the structural and stratigraphic framework of the Browse Basin.
The survey was acquired using the Seabird vessel, M/V Aquila Explorer. The Aquila utilised high-end Sercel Sentinel Solid Streamer technology and Bolt Source equipment (up to 6300 cu in) and was one of the best equipped 2D seismic vessels available to undertake this project. A full suite of additional products have been generated during the processing sequence and allows for further work such as AVO studies, inversion and basin modelling.
The Vampire 2D seismic survey was designed with extensive industry input with respect to line orientation and well-tie selection. In addition, its long offsets and acquisition parameters have addressed key problems found in legacy 2D and 3D open file datasets by providing significant uplift in data quality and superior imaging at all play levels, particularly within deeper structures across the basin. The survey allows identification of Jurassic, Triassic and Permian structures and provides insight into potentially untapped resources.
AVO analysis has proven to be problematic with open file vintage data across the basin. The Vampire 2D survey addresses this problem with its long offset acquisition and careful selection of processing methods and techniques. The PSDM processing provides additional uplift by accounting for complex anisotropy and ray pathing issues, especially below thick shale packages and below Cretaceous and Jurassic volcanics, allowing 3-term AVO inversion for reservoir characterization and field development. Gravity and magnetic data was also acquired and processed and available for delivery.
