The National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) is assessing Beach Energy’s proposal to undertake subsea installation and commissioning activities associated with the Otway offshore phase four development in Victoria.
Located in petroleum production licence VIC/L23, the Geographe gas field is in a water depth of 85m, 55km south of Port Campbell, Victoria.
Beach plans to tie-in production from two new wells – Geographe-4 and Geographe-5 – to the existing Otway gas production pipeline (OGPP).
The scope of the work also includes the installation of tie-in spools, electrical flying leads and hydraulic flying leads to connect the production wells to the existing gathering systems.
Beach Energy proposes to undertake the activity using a construction support vessel (CSV) between July 2021 and October 2021.
Following the works, production fluids will flow from the existing Geographe-2 well and the new Geographe-4 and Geographe-5 wells to the Geographe tee via the existing flexible flowline to the existing OGPP.
In addition, the company reported earlier this month it was approved to to drill up to six development wells and abandon three existing subsea wells in the Otway Basin, Victoria and Tasmania.
NOPSEMA approved Beach’s Otway development drilling and well abandonment program within permits VIC/L23 and T/L2.
Beach will commence the program before October 31, 2022 and expects that it will take up to 22 months to complete.
The scope of the project includes: the construction of four Thylacine development wells in petroleum title T/L2; the construction of two Geographe development wells in petroleum title VIC/L23; the permanent abandonment of a single Thylacine well (Thylacine-1) in petroleum title T/L2; and the permanent abandonment of two Geographe wells (Geographe-1 and Geographe-3) in petroleum title VIC/L23.
