  • Patent number: 8881805
    Abstract: Methods are described for using heated fluids from enhanced geothermal systems projects that recover geothermal heat from hot dry rock resources, and then injecting the heated pressurized fluids into a suitable rock formation to create an artificial geothermal energy reservoir. The artificial geothermal reservoir can then be used to store thermal energy by boosting the enthalpy of injected fluids by exchanging against heated fluids from other sources including a solar thermal power plant. Recovered heated fluids are utilized in a geothermal power plant and the spent geothermal fluids can be injected to recover additional thermal energy from hot dry rock resources. One embodiment is a geosolar electric power generation project to provide a steady and flexible source of renewable energy from a hot dry rock geothermal source integrated with a concentrating solar power project.

  • Patent number: 8869894
    Abstract: The present invention relates to methods and compositions that can be used to delay crystallization of a treatment solution so that thief zones or fractures are plugged in subterranean formations at a substantial distance from a wellbore. A supersaturated sodium aluminate solution, or other solutions, is introduced into the reservoir. The solution is relatively stable in the supersaturated state. Crystallization, or de-stabilizing the solution, can be controlled, which in turn plugs the thief zone or fracture at a designed point of time. By controlling the time that crystallization starts, that is, the induction period, thief zones that are located at a substantial distant from the wellbore can be plugged.

  • Patent number: 8820405
    Abstract: A method of segregating flowable materials in conjunction with a subterranean well can include segregating flowable cement from a fluid by placing a flowable barrier substance between the cement and the fluid, and the barrier substance substantially preventing displacement of the cement by force of gravity through the barrier substance and into the fluid. Another method of segregating flowable materials can include flowing a barrier substance into a wellbore above a fluid already in the wellbore, and then flowing cement into the wellbore above the barrier substance. A system for use in conjunction with a subterranean well can include a flowable cement isolated from a fluid by a flowable barrier substance positioned between the cement and the fluid, whereby the barrier substance substantially prevents displacement of the cement by force of gravity through the barrier substance and into the fluid.

  • Patent number: 8776879
    Abstract: Embodiments presented herein provide an evaporation based zero liquid discharge method for generation of up to 100% quality high pressure steam from produced water in the heavy oil production industry. De-oiled water is processed in an evaporation system producing a distillate that allows steam to be generated with either drum-type boilers operating at higher pressures or once-through steam generators (OTSGs) operating at higher vaporization rates. Evaporator blowdown is treated in a forced-circulation evaporator to provide a zero liquid discharge system that could recycle >98% of the deoiled water for industrial use. Exemplary embodiments of the invention provide at least one “straight sump” evaporator and at least one hybrid external mist eliminator. Embodiments of the evaporation method operate at a higher overall efficiency than those of the prior art by producing distillate at a higher enthalpy which minimizes the high pressure boiler preheating requirement.
