Bass Basin

BASS BASIN (victoria)

The Bass Basin is located offshore between the southern tip of Victoria and the northern margin of Tasmania in the shallow waters of Bass Strait.

In the Bass Basin, Beach extracts natural gas from the Yolla field, transporting it to shore via a 147 kilometre subsea pipeline. There, it joins the 32km-long raw gas pipeline to the BassGas processing plant near Lang Lang in Victoria.

Once processed, the gas from the Lang Lang Gas Plant is sold to retailers who use it for domestic or commercial consumption in the East Coast natural gas market.

BASSGAS

Construction of BassGas began in 2001.

Installation of offshore platform Yolla-A, drilling of Yolla-3 and Yolla-4 development wells, and the construction of an export pipeline and Lang Lang Gas Plant were completed in 2004. Gas production began in 2006.

Two additional production wells, Yolla-5 and Yolla-6, were drilled in 2015 and commenced production in August of that year.

Trefoil Seabed Assessment

Offshore exploration drilling is being undertaken to develop additional natural gas reserves within existing Commonwealth offshore exploration permits and production licenses, approximately 150 km from the Victorian coast.

Stakeholder consultation is an important part of preparing the project’s Environment Plan, it contributes to our understanding of local issues and concerns, as well as ensuring our planning manages potential impacts.

Beach has commenced engagement with the commercial fishing sector and other stakeholders and is keen to hear from any community members who would like further information or have any questions about this project.

Prion Seismic Survey

Beach Energy is planning to undertake a three-dimensional (3D) marine seismic survey (the Prion Seismic Survey) to enable assessment of the natural gas reservoirs in Commonwealth offshore retention licenses T/RL2, T/RL3, T/RL4 and T/RL5.

The activity is located approximately 73 km east of King Island, 57 km north of Stanley in Tasmania and 105 km south of Wonthaggi in Victoria at their closest points.

Stakeholder consultation is an important part of preparing the project’s Environment Plan, it contributes to our understanding of local issues and concerns and ensures our planning manages potential impacts.

Beach has commenced engagement with the commercial fishing sector who may operate in the area, along with other stakeholders. We are keen to meet and discuss this project with any potentially impacted stakeholders and welcome questions and feedback.
