Cluster analysis and petrophysical relationships for a geothermal reservoir in La Garriga area

Abstract

Porosity is a key parameter to appraise the geothermal potential of a reservoir. However, its determination is complex because it is not possible measure it direct, except when taking samples. The use of empirical laws to link porosity with geophysical properties can be an indirect way to determine it for different geological units present in an area of interest. Clustering methods have been used to jointly interpret seismic tomography and resistivity models from Valles Fault, near La Garriga, a geothermal area of interest. For each cluster, empirical laws that relate geophysical properties with porosity have been adjusted with porosity values that were obtained previously in the laboratory
