Heat sweep in a vertical fracture

Description

Heat Sweep In a Vertical Fracture Comparative Study This example is from the SPE-12099-PA paper: Pruess K. et al. 1984 Thermal effects of reinjection in geothermal reservoirs with major vertical fractures. J. Pet. Tech. 36(10): 1567-1578. DOI:10.2118/12099-PA . The problem concerns non-isothermal flow of water through a vertical fracture induced by fluid production and cold water injection. Heat exchange between fracture and confining impermeable rocks is simulated in full by introducing impermeable grid blocks in which only heat conduction equation is solved. There are 2400 grid blocks in total (rectilinear grid: 12*20*10). The initial reservoir temperature is 300 C. Cold water at 200 C is injected into the fracture through a point source whereas the fluid is produced using a well. The point source injection rate is given, whereas well is operating under constant bottom-hole pressure. The vapor phase does not appear under specified parameters of the problem. The temperature distribution after 5 year of production should be reported as well as the bottom-hole temperature versus time.
