Management of geothermal resources : PNOC-EDC experience

Abstract

The Philippine National Oil Company - Energy Development Corporation (PNOC-EDC) has acquired considerable operating experience after more than a decade of managing its geothermal production fields in the Philippines. PNOC-EDC was able to formulate immediate and long-term reservoir management strategies for the sustainability of the resource through intensive monitoring and thorough understanding of the fields’ behavior before and during exploitation. These management strategies are assiduously modified during the production stage to suit field behavior and optimize production. These management strategies including the monitoring aspects and parameters and the different methods of measuring these parameters are reviewed in this paper.
