Salamander-1: a geothermal well based on petroleum exploration results

Abstract

Panax Geothermal Ltd (“Panax”) has secured several Geothermal Exploration Licences (GELs), within troughs or grabens in the Otway Basin in southeast South Australia (Fig 1). Together the licences cover an area of more than 3,000 km2. The initial development of the Limestone Coast Geothermal Project is focused on the Penola Trough (GEL 223 and GEL 484; Fig. 2) - promoted by an existing comprehensive database of historical informaton from extensive oil and gas exploration and production. The Penola Trough has been subjected to intensive oil and gas exploration, including 27 deep petroleum wells with wireline logging and conventional core measurements of reservoir porosity and permeability. In addition, 321 km2 of 3D seismic and a significant amount of 2D seismic data have been acquired in this area. All of this data is available as part of a public open file database.
