GSEL 759, Otway Basin
Onshore South Australia
The GSEL 759 Gas Storage Exploration Licence was awarded 100% to 3D Oil in July 2022. The permit is located only 20km southeast of Mount Gambier and proximal to the South East Pipeline System (SEPS) (Figure 1). The licence covers an area of 1.02km2 and is centrally located around the plugged and abandoned Caroline-1 wellhead, over part of the now depleted Caroline Field.

The Company continues a gas storage feasibility study into Caroline Field, with the depleted CO2 reservoir potentially suitable for the storage of hydrogen, natural gas or carbon dioxide. Detailed reservoir/seal studies are planned to understand the reservoir deliverability and seal integrity, in combination with ongoing geomechanics and geophysical studies.
