Ocean Hill 3D Seismic Survey

Closed 19 Aug 2021

Opened 13 Aug 2021


Ocean Hill Pty Ltd propose to undertake a three-dimensional (3D) seismic acquisition survey within petroleum exploration permits EP495, EP454 and EP320 in the Midwest region of Western Australia. 

The proposal comprises a disturbance footprint of 801.91 hectares (ha) within a development envelope of 28,203.54 ha. A total of 113.52 ha of native vegetation would require clearing within the disturbance footprint. Following completion of proposed activities, seismic access tracks would be rehabilitated. 

The seismic survey is proposed to be undertaken over a total activity period of 13 weeks, including mobilisation and demobilisation.

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.

What happens next

Following the seven day public comment period and consideration of any comments received, the EPA will decide whether or not this proposal requires environmental impact assessment and, if so, what level of assessment will be applied.

The EPA's decisions on level of assessment are released each Monday on the EPA's website.
