    Abstract: A method for modeling geomechanical subsurface pumped energy storage systems. In one embodiment, the method comprises applying a mechanical model developed for storage lens behavior during flowback (production), shut-in, and inflation (storage) stages. The model couples elastic deformation of the lens with Darcy-Weisbach fluid flow spanning the laminar to turbulent regimes, and includes an energy-based inlet boundary condition governing fluid flow rate out of the lens and up to the Earth's surface. The model also introduces pressure-dependent leakoff of fluid to the surrounding rock and the impact of intact rock bridges, which can arise from the lens having multiple petals or lobes, on lens compliance.

    Abstract: Energy is stored by injecting fluid into a hydraulic fracture in the earth and producing the fluid back while recovering power and/or desalinating water. The method is particularly adapted to storage of large amounts of energy such as in grid-scale electric energy systems. The hydraulic fracture may be formed and treated with resin so as to limit fluid loss and to increase propagation pressure. The fluid may be water containing a dissolved salt or fresh water and a portion or all of the water may be desalinated using pressure in the water when it is produced.

    Abstract: Compositions are provided for preventing or alleviating loss of fluids from natural or artificial reservoirs formed in subterranean geological formations and methods for deployment of said compositions. The compositions can be delivered to the subterranean reservoirs in any number of steps and are comprised of rock surface adhesion promoter(s), particles that may consist of solids, gels and liquids, crosslinking agent(s) and a liquid medium. The method of the invention uses the composition of the invention in preventing or alleviating loss of fluid stored in a reservoir existing in a subterranean formation. In the method, the composition is preferably provided in a series of weighted or unweighted “pills” for introduction into the reservoir. Such a series may include from one to any number of consecutive treatments. Multiple pills or treatments may be used if needed.

    Abstract: A system and method for geothermal resource development which comprises generating a plunging fracture at a wellbore using a dense fracture fluid. In one embodiment a compliant elastic material may be pushed to the propagating tips of fractures where they screen out the fracture tip and stop fracture propagation. The method may further comprise injecting additional fluid to increase the net pressure in the fracture, thereby increasing the width of the fracture. The system may further comprise providing a heat exchanger disposed about the bottom of the wellbore or providing an apparatus for circulating water into the fracture in order to address natural convection occurring in the fracture.

    Abstract: A method for improved borehole completion. In one embodiment, the method comprises removing a section of casing entirely and cutting a notch through the cement and into the surrounding rock formation, wherein the notch optimally comprise a symmetric triangle terminating in a sharp point oriented perpendicular to the casing axis. Flow may be further optimized by extending the notch as far as practical into the rock matrix to increase the effective diameter of the wellbore and increase the length of the intersection between the fracture and the wellbore.
