摘要： The present invention provides a method for selecting the location of a stimulating well, comprising the steps of conducting a geological study of a field containing a geothermal hydrothermal resource by operating geological useful equipment, determining a maximum horizontal stress line within said field by means of a device, generating a map of existing wells including a plurality of sub-commercial wells within said field relative to said maximum horizontal stress line, measuring a distance between each of said sub-commercial wells and the maximum horizontal stress line, determining that those sub-commercial wells aligned with, or located relatively close to the maximum horizontal stress line are stimulatable, and selecting a location of a stimulating well for stimulating the stimulatable well that is separated less than an anticipated fracture propagating distance from said stimulatable well.
