Maibarara Geothermal, Inc. (MGI) completed bore output testing that confirmed sufficient steam supply under the wellheads for its 10MW Maibarara-2 (M2) expansion project. MGI currently operates an integrated 20MW geothermal power facility in Sto. Tomas, Batangas that it put into commercial operations on February 8, 2014.

MGI started its expansion project in the second half of 2014 by drilling two new wells MB15RD and MB16D which were successfully completed 5 days and 14 days ahead of schedule, respectively. MB16D was flow-tested from December 2014 to February 2015, while MB15RD underwent similar discharge tests from April to May 2015. At the end of May, MB15RD, which was originally designed and drilled as an injection well, had attained commercial wellhead pressure, mass flow, and MW output at full-bore opening.

The Department of Energy (DOE) Director Mario Marasigan of the Renewable Energy Management Bureau (REMB) said, “We are pleased with the outcome of MGI’s drilling and testing programs for its expansion project and the DOE looks forward to a new 10MW power station in MGI in 2017. Despite its modest size, MGI’s expansion unit combines the advantages of being base-loaded, renewable, and free of harmful greenhouse gas emissions. Just as important, the host LGUs can expect additional royalties and benefits when the new plant becomes operational.”

MGI is a joint-venture company owned by PetroGreen Energy, Inc. (PGEC) (65%), Trans-Asia Oil & Energy Development Corporation (25%), and PNOC Renewables Corporation (10%). PGEC is a subsidiary of PetroEnergy Resources Corporation.
