Abstract: 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.

Abstract: The invention relates to a packer for a wellbore, comprising a central tubular element (7) covered by a deformable peripheral sleeve (5). Fluid is injected inside the tubular element under pressure in order to form said sleeve (5) and to apply it to the walls of the wellbore (3). The inventive device is characterized in that the deformable sleeve (5) is made out of metal and the inner wall of the sleeve (5) comprises at least one annular chamber (17) that extends over at least one part of the surface of the sleeve (5) and communicates with the inside of the packer via an orifice (19), whereby said chamber (17) is filled with a material that is non-miscible with respect to the wellbore fluid prior to the injection of said fluid under pressure.
