A preliminary database design for geothermal fields in El Salvador

Abstract

A preliminary database design has been carried out for two El Salvador geothermal fields. The database contains thermodynamic information, such as downhole temperatures and pressures, wellhead mass and heat flow with time. The database is considered a necessary component in modern computer networks, consisting of central and peripherical devices, where communication takes place between the clients and servers and different databases. In this work an Oracle relational database and associated tools were used for the database development, such as PL/SQL and Oracle Developer/2000. The database is designed for a UNIX operating system and utilizes several of it's tools for data processing and plotting. The present database is designed to be user friendly. It already stores and retrieves data for several wells in El Salvador geothermal fields. The database can be expanded to store other information not considered in the design. Also, it is flexible and easy to modify, with the possibility of handling substantial amounts of data.
