With drilling works now completed, Basic Energy Corp. and Phinma Energy Corp. are now determining resources at the Mabini geothermal project in Batangas.
The consortium has fulfilled its commitment with the Department of Energy (DOE) for completing the drilling works for Geothermal Service Contract No. 8.
Basic Energy said drilling reached the target depth of 1, 679 meters, and preparations to set perforated liners are being done.
“Testing of the well aimed at obtaining temperature, pressure, and permeability data, to be performed by its contractor, Scientific Drilling International (SDI), shall commence shortly,” the firm said.
Basic Energy senior vice president and general manager Anthony Cuaycong said completion tests will last up to three days and are intended to set baselines that will allow Basic Energy to assess the resources.
“After the completion test, there is a heat-up period of up to one and a half months, during which time surveys will be conducted to check well response after specific ‘rest’ periods,” Cuaycong said.
Pre-feasibility studies show that Service Contract no. 8, which covers 3, 841 hectares, can yield between 20 to 60 megawatts of power.
