Application of Database in Monitoring the Performance of Geothermal Steam Fields and Power Plants in the Philippines

Abstract

Database is vital for the efficient development and management of geothermal resources. The Philippines with an installed geothermal energy capacity of 1930.89 MWe and still with a great potential for geothermal exploration and development is generating an increasing volume of geothermal data. A computerized geothermal database was designed and developed for storage, retrieval and manipulation of data collected from geothermal fields. The database will be used and applied by the Philippine Department of Energy (DOE) in monitoring the performance of geothermal steam fields and power plants to avoid over-exploitation of the resource, and assure sustainable geothermal resource management.

Well information, reservoir monitoring parameters, drilling information and power plant generation are the essential data considered for the database development using the Oracle Relational Database Management System (RDBMS). Oracle Developer tools and other related computer softwares were also utilized to provide fast, simple and easy data input, editing, viewing, reporting and graphing.
