METHOD AND SYSTEM FOR IDENTIFYING ZONES OF HIGH FRACTURE CONNECTIVITY IN A GEOLOGIC/GEOTHERMAL RESERVOIR

摘要

A method and system for identifying zones of relative high fracture connectivity in a geologic formation such as a geothermal reservoir or other subsurface region, which comprises comparing well-log data on the distribution of K relative to Th and/or U and assessing for zones of increased fracture connectivity in the rock from the comparison. The distribution of spatial statistics of K is compared to the distribution of spatial statistics of Th and/or U to determine zones of relatively high fracture connectivity/permeability. Such information may be used in a drilling operation for improving extraction well performance.
