Booming 1O MW For BN6 In Biliran Geothermal Field


Biliran Geothermal Field

A spectacular 10 MW well with neutral and benign fluids has been tested in Biliran Geothermal Field, the first commercial well drilled in an exploration area for more than a decade, since the hectic days of geothermal development in the Philippines. BN6 was the third well drilled in the Island of Biliran by Biliran Geothermal Inc. (BGI), a consortium of FEDCO, a local geothermal energy developer and international geothermal consulting firm, and Orka Energy of Iceland. This well has basically confirmed the existence of a geothermal resource in the island although a prolonged testing is yet to be completed. While the first two wells drilled by the consortium have proven to be similarly productive, with temperatures in the range of 280-340C, wellbore problems have delayed their output testing. All these wells encountered good permeability exceeding average indices of commercial wells in the Philippines.

BGI planned to commission the first unit with a 50 MW capacity by 2016 to be followed by another 50 MW thereafter. To mitigate the drilling and geological risks, a drilling technology that employs underbalance drilling was adopted and proven to be successful in managing the quality of fluids. It also ensures that damage to formations is minimized allowing formation permeability to be preserved. The technical aspects of the operations in the project was handled by a composite of experts from Iceland, New Zealand and the Philippines which are composed primarily of FEDCO personnel.

Biliran Geothermal Field counts as one of the major geothermal fields in the world where FEDCO services have been rendered and adds another milestone in its exemplary success rate in geothermal exploration. FEDCO has been involved in El Salvador, Iran, Chile, Iceland, New Zealand, Kenya, Taiwan, Indonesia and in most exploration areas in the Philippines. The exploration phase including the resource assessment of the field was handled by FEDCO from 2008-2009 which covered geological, geochemical and geophysical surveys.

Basic Energy Pursues 20-MW Geothermal Plan

PUBLICLY LISTED Basic Energy Corp. has tapped Filtech Energy Drilling Corp. to conduct a prefeasibility study for its planned 20-megawatt Mabini geothermal energy project in Batangas.

In a disclosure to the Philippine Stock Exchange, Basic Energy said the prefeasibility study would consist of technical predevelopment, technical development, environmental and social, financial and economics, project schedule and implementation, as well as risk assessment.

According to Basic Energy, the study would validate the Controlled Magneto-Telluric (CSMT) survey that Basic Energy conducted last year and provide a more detailed geophysical and geologic evaluation, determine the best drilling locations, and simulate the technical, operational and economic feasibility of a 20-MW geothermal power plant, assuming a success drilling phase.

Prospective sites

With the CSMT survey, Basic Energy was able to look into some 60 pre-identified, prospective geothermal sites. It was completed in May last year.

The Mabini geothermal service contract was awarded to Basic Energy by the Department of Energy on July 10, 2008. Basic Energy had then committed to invest $3.15 million for initial exploration activities.

Under the exploration program, Basic Energy was expected to conduct geophysical and geological surveys covering 3,481 hectares in the Calumpan Peninsula in Mabini, Batangas.

The company’s initial assessments then indicated that the area had a good potential for power generation that could be developed within a two- to three-year period considering the existence of adequate infrastructure, adjacency to transmission lines and a strong power demand in the area.
