Abstract: A method of forming a permeable proppant pack in a geothermal formation can include injecting a fracturing fluid into a fracture of a geothermal formation having a formation temperature greater than about 275° C. The fracturing fluid can include proppants having a core of a solid material that is thermally stable at the formation temperature. The core can be at least partially coated with a resin coating that includes a polymer having a decomposition temperature below the formation temperature and a melting temperature below the decomposition temperature. The resin coating can be decomposed by the heat from the geothermal formation and the core of the proppants can remain in the fracture after the resin coating has decomposed.

Abstract: Systems and methods for cooling electrical components of an electrical submersible pump in a subterranean well are disclosed. Cooling fluid is delivered from a location proximate ground surface through a conduit to a submerged electrical pump motor in a subterranean well to cool the submerged electrical pump motor.

Abstract: A system and method for extending a slotted liner shoe is disclosed. According to one embodiment, a low density material is injected into a liner having a plurality of openings. The liner is suspended below a cemented casing in a wellbore of a well in a subterranean formation. The low density material extrudes through a lower portion of the liner into an annulus between the liner and the wellbore. A cement is circulated into the liner above the low density material. The cement extrudes through an upper portion of the liner into the annulus between the liner and the wellbore. Water is displaced from the wellbore, and a solid cemented casing string is formed at a desired depth.

Abstract: Systems and methods can include maximizing energy recovery from a subterranean formation. According to one embodiment, a selected subterranean open-hole interval is isolated and at least one fracture is stimulated in the isolated subterranean open-hole interval.

Abstract: Systems, methods and compositions for temporary sealing fractures in subterranean formations employ at least one constituent for temporary sealing a fracture in a subterranean well. The degradation kinetics of the composition is dependent upon at least one degradation temperature-time parameter for designating a temperature range and a time at which the composition degrades.

Abstract: 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.

Abstract: A method and system for providing a temporary sealant within a wellbore of a subterranean formation is disclosed. According to one embodiment, the temporary sealant comprises a particulate material and a liquid. The particulate material and the liquid are mixed to a predetermined dilution ratio. The temporary sealant is pumped into fractures via an open hole of the wellbore. The particulate material accumulates and is left within the fractures to set. Over a predetermined period of time, the particulate material degrades, disintegrates, or dissolves within the fractures.

Abstract: A geo-cooling system of specified cooling capacity for cooling a known heat load is disclosed. The system includes a cool water aquifer, a cool water production well and a heated water injection well. The cool water production well is open to the cool water aquifer and in hydrologic communication with a subterranean heat exchange area that provides requisite cooling capacity to a known heat load. The heated water injection well is in hydrologic communication with the subterranean heat exchange area and open to the cool water aquifer at a prescribed distance from the cool water production well. The prescribed distance between the cool water production well and the heated water injection well is at least based on the available size of a subterranean heat exchange area including a portion of the cool water aquifer that hydrologically communicates between the heated water injection well and the cool water production well.
