Olympus Broadband 3D Reprocessing

Comprehensive Seismic Imaging for Enhanced Exploration in the North Carnarvon Basin

The Olympus Broadband 3D Reprocessing project merges 20 existing 3D seismic datasets including Searcher’s Non-Exclusive Foxhound East and Drop Bear 3D surveys. With seamless integration, the project unveils a comprehensive image of the Northern Carnarvon Basin, which sits at the heart of the Australian North West Shelf’s most bountiful hydrocarbon trends. Olympus seeks to enhance this exploration infrastructure, extending play fairways into lightly explored surrounding regions, and lighting the path to future exploration victories.

These surveys, processed as a single unified volume, received the full-service treatment of a comprehensive broadband PSTM and PSDM flow, resulting in a total volume exceeding 19,100 km². Stretching northward from the Rankin Platform, the survey exposes a broad swath of prime Jurassic reservoirs. Reprocessing efforts focused on resolving fault seals and envisioning complex migration pathways, keys that could unlock further discoveries in the area. Olympus 3D is the bedrock of your future exploration and development strategies in this promising region.
