MGI Completes 3rd Production Well Ahead of Schedule, Begins Drilling New Reinjection Well

August 31, 2012

Maibarara Geothermal, Inc. (MGI), the service contractor of the Department of Energy (DOE) for the Maibarara geothermal field in Sto Tomas, Batangas, will start drilling well MB-14RD on August 30, 2012 using DESCO Rig #30.  The well will be used for reinjecting condensate fluids coming from the 20 MW geothermal plant back to the subsurface reservoir to recharge the system.  Construction of the power plant is on-going and proceeding on schedule.  MGI plans to commercially operate the plant in late 2013, making it the first geothermal power station in the country in six years and the first under the present Aquino administration.  MGI is the joint venture company owned 65% by PetroEnergy Resources Corp., through its 100%-owned subsidiary PetroGreen Energy Corp., 25% by Trans-Asia Oil, and 10% by PNOC-Renewables Corp. (PNOC-RC).

On July 10, 2012, MGI spudded well MB-12D, the third production borehole that will supply steam to the 20 MW power plant.  MGI’s drilling team successfully reached its target depth of 2150 m on August 5, 2010. After conducting the necessary completion tests on the borehole, the rig was released on August 10, 2010, successfully ending the well drilling fourteen days ahead of schedule.  The rig was then transferred to nearby production well Mai-9D where it conducted work-over operations to clear the bore of shallow blockages.  Work-over operations on Mai-9D was completed on August 23, and the rig was then moved to the site of well MB-14RD.

MGI President F. G. Delfin, Jr. declared “MGI and our Partners are pleased with the efficient completion of well MB-12D but we are equally delighted that our 2012 drilling campaign has gone safely, thus far.  This affirms the Silver Safety Award bestowed last July on MGI by DOE Secretary Jose Rene Almendras and Dir. Mario C. Marasigan.”

 

DOE Undersecretary Jose M. Layug, Jr. said, “Maibarara is a testament of a successful public-private partnership envisioned by the Aquino administration. We hope that the Maibarara project will encourage more renewable energy investment in the Philippines”.

 

Completion tests and heat-up surveys conducted by MGI on well MB-12D strongly indicate that the well achieved its reservoir and geological objectives.  Results from injectivity and pressure fall-off tests showed that the well intersected its targeted permeable formation, marked by high permeability-thickness product values.  Continuing downhole temperature and pressure surveys attest to the fast thermal recovery of the well.  Production tests to be conducted later in the year will determine the well’s actual MW output.
