Pilot Energy Limited is proposing to undertake the Eureka 3D Marine Seismic Survey (MSS) in exploration permit area WA-481-P, Production Licence WA-31-L and an area of open acreage, which are located on the mid-west coast of Western Australia (WA), in the northern Perth Basin. The active source area covers approximately 946 km2. The active source area is surrounded by a larger operational area (approximately 1,575 km2). The seismic source will not be discharged within the operational area. The operational area at its closest is approximately 6 km west of Dongara and 54 km south of Geraldton. The survey will involve a single seismic survey vessel towing a seismic source array with a total volume of 2,495 cubic inches (in the streamer area) and 1420 cubic inches (in the nodal area), at a water depth of approximately 11 to 52 m. The reflected sound wave will be received by a minimum of 6 hydrophone streamers. Each streamer will be up to 6,150 m in length, spaced 100 m apart and towed at a depth of approximately 7 m. The nodal area will be acquired using an ocean bottom node technology rather than towed streamers. This will require deployment of the small and light weight nodes, via diver or autonomous vehicle, in a square grid of approximately 250m x 250m in the required areas. The Eureka 3D MSS will take a maximum of 40 days to acquire and will be undertaken within the acquisition window of February to March (inclusive) during 2026. |
