  • Methods of forming a permeable proppant pack in a geothermal formation
    Patent number: 11859129
    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.
