2020 Australian Offshore Acreage Release

Searcher in Australia

The annual Offshore Petroleum Exploration Acreage Release 2020 is now open for consultation.

The North West Shelf is the Australian’s explorers playground with recent discoveries having changed the perception of oil prospectivity in the region. The discoveries have reinstated that the area remains underexplored and still holds a great deal of potential. Several play zones that had been previously overlooked in the lower Triassic have now been highlighted with recent seismic acquisition and modern imaging.

The North West Shelf is Searcher’s backyard with extensive coverage and years of experience within the region. Searcher’s data library provides explorers with modern seismic and geoscience datasets that will help support them in more successful drilling programs.

Sink your teeth into the Browse Basin with Searcher's Vampire

Approximately 7000 km of ready to interpret long-offset modern PSTM and PSDM seismic data is available, tied to 60 key wells.  The dataset provides an easily accessible regional overview of the structural and stratigraphic framework of the Browse Basin and covers much of the 2020 Offshore Acreage Release Consultation Areas within the area.

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.

Screen Australia wide with OpenSeis on Saismic

The rectified Australian OpenSeis 2D and 3D seismic data is loaded and hosted on Searcher’s multi-client platform, Saismic, for consistent and instant online access for explorers.

Saismic is a transformative web-based platform that offers seismic Data as a Service (DaaS) with support for deep learning and advanced analytics. The Saismic GIS web portal has traditional functionalities of online viewing, export to SEGY functions and offers a global collection of rectified open-file seismic data.

The Australian OpenSeis 2D & 3D Seismic consists of both 2D and 3D vintage seismic data which has been rectified in a post-stack reprocessing method. Searcher has applied its proprietary OpenSeis post-stack reprocessing method to the Australian database to rectify navigation, metadata, amplitude, phase and time to create a contiguous database that can be easily loaded into any interpretation software.

The Australian wide coverage offers data in regional screening, any area of interest and right down to block sized coverage, ready in an instant.
