    摘要： An injection backflow technique for measuring fracture surface area adjacent to a wellbore is disclosed. According to one embodiment, a method comprises measuring an initial temperature profile along the length of a wellbore. A tracer composition is injected into the wellbore at an initial concentration. The tracer composition includes a reactive tracer and a secondary tracer that is less reactive than the reactive tracer. The tracer composition diffuses within subterranean reservoir for a time. A secondary tracer concentration and a reactive tracer concentration are measured as a function of time. A reservoir fracture surface area is calculated using a reservoir fluid flow model.

    摘要： A method for modeling fracture network and fracture network growth during stimulation in subsurface formations is disclosed. According to one embodiment, a computer implemented method comprises receiving data comprising characteristics of a subsurface formation, generating simulated fractures based upon the characteristics of the subsurface formation, simulating stimulation of the simulated fractures by creating a plurality of injection points and stimulating from every injection point of the plurality of injection points simultaneously. Simulation results are output and displayed, the simulation results including at least one of fluid volume, fluid pressure, three dimensional geometry of a stimulated volume, potential permeability enhancement, and simulated seismic activity.

    摘要： A method can include introducing a particulate diverting agent into a first fracture within an underground reservoir formation. The particulate diverting agent can at least partially hydraulically isolate the first fracture. The particulate diverting agent can also be a temporary material which substantially degrades over an extended time. The underground reservoir formation can be stimulated with a stimulation fluid sufficient to expand a second fracture within the underground reservoir formation. The particulate diverting agent can then be allowed to substantially degrade.

    摘要： A system and method for determining the most favorable locations for enhanced geothermal system applications are disclosed. According to one embodiment, a computer implemented method comprises receiving input data comprising characteristics of a subsurface geothermal resource and spatial parameters associated with extracting the subsurface geothermal resource, generating formulas and look-up tables based upon the input data, wherein the formulas and look-up tables relate a cost per rate to spatial attributes associated with the subsurface geothermal resource. Geographic information is combined with the formulas and look-up tables to create a map of the cost of each component of a plurality of components. A map is output of a total cost of electricity generation capability associated with the subsurface geothermal resource, wherein the total cost is calculated by summing the cost of each component of the plurality of components.
