Torrens Energy Limited (Torrens Energy) has commenced heat flow drilling at its wholly owned geothermal exploration license (GEL) areas in South Australia. Planned exploration will initially test the Adelaide Plains project, about 75 kilometers north of the city of Adelaide, and then move (north) to the Port Augusta Project once Governmental approvals are in place. These two projects will be drilled for a total of about 3000 meters over six holes.

The drilling will be done by applying a combination of ‘shallow’ heat flow drilling (500m depth, 15km spacing) with the company’s innovative 3D temperature field modelling (3D-TFM) methodology.

The 3D-TFM is designed to efficiently ‘map’ temperature variation over large prospective areas, at a fraction of the cost of conventional deeper exploration drilling.

Activity is fully funded, and supported by a $3 million Matched Grant under the Australian Government’s Renewable Energy Development Initiative (REDI).

The exploration heat flow drilling programme is expected to run through to April 2009, with results returned after holes have had time equilibrate.
