A multi-well study was conducted in the Piceance Basin in Northwestern Colorado because of the unique effect of lithology on the geothermal gradient. Coal, sand and shale sequences which impact the geothermal gradient must...

.... The model is used to investigate the impact of well placement in enhanced geothermal systems by considering the effect of backbone fractures, dead-end fractures, and fractures away from production wells. The findings provide guidance on well placement in fractured reservoirs to maximize the efficiency...

Figure 9 shows a schematic plot of an ideal enhanced geothermal system in which the injection wells and production wells are drilled between each other. The injection wells are hydraulically fractured, and the planar fractures connect the two production wells...

... wells. This is leading to a rapid proliferation of new geothermal installations worldwide. In addition, there is considerable excitement surrounding the concept of enhanced geothermal systems (EGS). In enhanced geothermal systems wells are drilled into hot, impermeable bedrock and hydraulic fracturing...

... Abstract Exploiting deep geothermal energy is always an important topic in energy fields, however, there are still no well-established methods to extract heat energy from hot dry rock (HDR) in the scale of commercialization. Hydraulic stimulation or fluid-rock interaction can cause fracture...
