The Olympus Broadband 3D Reprocessed project is a merged seismic dataset providing broadband pre-stack time (PSTM) and pre-stack depth migration (PSDM) products over the North Carnarvon Basin of the Australian North West Shelf.
The Olympus Broadband 3D project comprises of 20 existing 3D seismic datasets including Searcher’s own Foxhound East and DropBear 3D surveys. This project is unique in that it will provide coherent regional 3D seismic imaging of one of the most prolific hydrocarbon trends on this shelf, serve as an exploration framework for extending viable play fairways to the under explored surrounding areas and facilitate future successful exploration efforts.
All surveys have been processed as one volume from field tapes through a comprehensive broadband PSTM and PSDM flow. This provides a complete, unified, dataset covering a complex geological region of the North Carnarvon Basin, giving a total volume of over 19,100 km².
The survey provides regional 3D seismic imaging of one of the most prolific hydrocarbon trends on this shelf. It will serve as an exploration framework for extending viable play fairways to the under explored surrounding areas and will facilitate future successful exploration efforts. The Olympus 3D extends northward from the Rankin Platform and covers an extensive fairway of high quality Jurassic reservoirs in the Angel, Calypso and Legendre Formations, with multiple potential sources including the Dingo Claystone and the Muderong Shale.
The processing effort specifically focused on resolving fault seals and imaging complex migration pathways which may prove the key to unlocking further discoveries in the area.
