Geothermal Well Logging and Testing

Abstract

Logging and testing of geothermal wells are essential segments of any field exploration and development strategy addressing relevant reservoir engineering and resource management issues. They constitute in deed a too vast domain, actually the substance of numerous books, papers and manuals, to be thoroughly challenged in the framework of this presentation. Therefore the scope of the exercise will be limited and focus instead on recalls of well logging and testing basic principles and illustrated by selected field applications the latter restricted to low to medium temperature, single phase liquid, geothermal sources and sedimentary host rock environments. The foregoing may be regarded as a set of guide lines, whose methodology could be applied while tackling similar resource settings and development problematics.
