Searcher Seismic Expands Multi-Client Library on North West Shelf

Australia-based Searcher Seismic Pty Ltd. reported that it is extending several key projects in the North West Shelf off Australia in order to better facilitate regional evaluations for the oil and gas industry.

Searcher’s 2D Super-Tie library has been reprocessed from field tape with modern pre-stacked time migrated (PSTM) processing workflow and can be interpreted as a single uniform seismic dataset consisting of over 100,000 kilometers of multi vintage 2D seismic data on the North West Shelf. The newest extension to this dataset is the Inner Browse Super-Tie, consisting of 10,000 kilometers of data. The project is focused on offering a regional evaluation tool to define basinal structure and stratigraphy as well as having the resolution and fidelity to assess known discoveries with AVO products for look-a-like features.

The hiQbe Regional Velocity Cube, in partnership with Aker Solutions, provides a high quality, regionally consistent velocity volume that previously covered the Carnarvon, Offshore Canning and Browse Basins. This project has now been extended to include the Bonaparte Basin. The velocity 3D volume has been filtered, levelled and balanced from stacking velocities of over 300 open file 2D and 3D seismic surveys, sourced from our OpenSeis database, as well as over 100,000 kilometers of recently reprocessed Super-Tie PSTM data. Depth conversion with the calibrated average velocity cube produces anomaly free depth products that seamlessly tie to the wells.

Delivery of these latest extensions is expected in 4Q 2013, and previously existing data is available now.
