Gippsland Basin, Victoria and Tasmania

The Gippsland Basin is located in southeastern Victoria and extends into Tasmanian waters. The basin is primarily situated offshore with water depths reaching up to 4000 m to greater than 3000 m. Comprising a world-class petroleum province, the Gippsland Basin has giant oil and gas producing fields, existing infrastructure with widespread seismic coverage and extensive well distribution. The release areas are located along the southern margin of the Gippsland Basin. The release areas are based on the expected fluid migration pathways.

Reservoir:  Top Latrobe Group and intra-Latrobe Group.
Seal:            Lakes Entrance Formation regional seal; intra-formational seals of the Latrobe Group.
Trap:            Major pinch-out plays and migration dissolution/residual trapping.

GIPP-01, GIPP-02 AND GIPP-03, Southern Platform, Gippsland Basin

GIPP-01, GIPP-02 and GIPP-03 are located along the southern Gippsland Basin margin and cover much of the Southern Platform in offshore Victoria and Tasmania (Figure 1).

Release area GIPP-01 (Figure 2) covers an area of approximately 4385 square kilometres and 67 graticular blocks or parts thereof. Release area GIPP-02 (Figure 2) covers an area of approximately 3805 square kilometres and 57 graticular blocks, or parts thereof. Release area GIPP-03 (Figure 2) covers an area of approximately 5460 square kilometres and 82 graticular blocks or parts thereof.
