Petratherm, a company which explores and develops geothermal energy, has completed various geothermal projects. The Paralana geothermal project, undertaken by the company, covers more than 500 square kilometers of hot rock granite resources in the Mount Painter region, South Australia. The Paralana Engineered Geothermal System (EGS) project is located in the north of Adelaide, South Australia. The place has a high temperature of more than 200 degrees Celsius at drillable depths.
The high temperature of the place is contributed by the meta-sedimentary rocks and high heat production granites. For the Paralana EGS project, the first deep drilling of production grade is planned for a depth of four kilometers. The planned development of EGS reservoir includes large hydraulic stimulation of numerous zones in the sedimentary overburden. The company has completed an independent statement of inferred resources in accordance with the Australian Geothermal reporting code.
Petratherm has planned to deliver at least 260 megawatts of base load power from the Paralana site, on a long term basis. The generated power will be fed into the National electricity grid. The next phase of work for the Paralana EGS project includes drilling of an injector and a producer well in Poontana basin. Later, a fluid circulation cell will be developed between the wells. The wells will be drilled to construct an electricity plant with a capacity of 7.5 megawatts.
