Offshore Gippsland Basin – Exploration Permit – Vic/P47
- Australia’s premier hydrocarbon province
- Located 200 km east of Melbourne
- Exploration commenced in 1924
- Over 400 exploration wells drilled
- Some 90,000 line km of 2D seismic
- More than forty 3D seismic surveys
- Gas infrastructure well developed with a network of pipelines to onshore gas processing facilities at Longford and Orbost.
- Gas delivered across southeastern Australia as far as Sydney, Adelaide and Tasmania
- Operators include Esso/Woodside, Beach, 3D-Oil and Cooper Energy
- Esso/Woodside have developed the Kipper gas field adjacent to Vic/P47 investing over $5.5 billion in the basin as part of its Kipper – Tuna – Turrum gas project
Vic/P47
- EMP holds 100% of 202 km2 Vic/P47 Permit
- EMP is Operator of the Permit
- Water depths: 20 – 85 m
- Two-gas discovery wells drilled within the permit:
- Judith-1 drilled by Shell in 1989
- Moby-1 drilled by Bass Strait Oil in 2004
- 3D seismic reprocessing, mapping and interpretation completed in 2017 and 2022
- 1.8 Tcf Gas in Place Estimate at Judith Prospect and 622 Bcf (P50) at Kipper and Golden Beach Sands
- Longtom gas field 15 km to west of Vic/P47 provides a good analogy for successful appraisal, potential development and production from Emperor Group Reservoirs at Judith
- Judith is located 2 km north of the Kipper Gas Field recently into production by Esso / Woodside
- Application to extend permit for lodged with NOPTA in September 2023.
