Value of information analysis using geothermal field data: accounting for multiple interpretations & determining new drilling locations
Year: 2015
Type: conference-paper
Abstract: Summary We present a value of information analysis for MT data for locating high steam flow regions of a geothermal resource. The high electrical conductivity feature in volcanic geothermal settings, known as the clay cap, can be indicative of geothermal alteration occurring just above the resource. We demonstrate how two alternative interpretations of the clay cap from one 3D electrical conductivity model can be used to estimate the value of geophysical information. Our results indicate that the final VOI estimate depends on the different interpretations of the clay cap and the assigned prior probability of steam flow magnitude. Additionally, we demonstrate how these VOI evaluations can be used to guide future drilling locations.
