Eureka 3D Marine Seismic Survey

Overview

Pilot Energy Limited proposes to undertake marine seismic surveying 7 kilometres off the mid-west coast of Western Australia, south of Dongara. The survey aims to acquire three-dimensional seismic data to improve understanding of subsurface geology and assess potential natural gas resources. 

The proposal involves a purpose-built survey vessel traversing the survey area, generating seismic sound using controlled releases of compressed air. The vessels will tow 6 cables approximately 6,000 metres long to capture sound levels reflected from beneath the sea-floor. In shallower areas, seabed-mounted ocean bottom nodes will be temporarily deployed and later retrieved. No drilling, seabed excavation, or permanent infrastructure is proposed. 

Why your views matter

At this initial stage of the EIA process, comment is simply sought on whether or not the EPA should assess a proposal and, if so, what level of assessment is considered appropriate.
