Green Rock counts down to Hungary geothermal drilling

Production testing will take place to determine the hot water flow rates of the two wells, known as Ortaháza-3 and Ortaháza-5, which were both drilled to depths of about 3000m.

Once testing is complete in the third quarter of this year, Green Rock plans to undertake a feasibility study into establishing a geothermal power plant and direct heat supply for industry.

During the testing, one well will be used for thermal water production and the other well for injecting the water back into a separate water-bearing horizon, the company said.

The tests are designed to gather detailed data on the wells and water-bearing zones for the subsequent construction and operation of the planned geothermal power plant, it added.

Green Rock said the size of the development would depend on the quality and sustainability of the water flow rate.

The aim of this first project is to install a 2-5MW geothermal power plant, to be commissioned in 2008.
