This example is from the SPE-10509-PA paper: Pruess K. et al. 1985 A practical method for modelling fluid and heat flow in fractures porous media. SPE J. 25(1): 14-26. DOI:10.2118/10509-PA. The 2D areal problem concerns non-isothermal flow of water and steam in fractured reservoir. The fluid transport occurs only through the fractures, whereas the matrix blocks are impermeable. At the initial moment of time the reservoir is saturated with hot water at 300 C and at high pressure above water boiling pressure. The fluid extraction though the production wells results in the pressure drop down and water boiling. Cold water is reinjected in the reservoir in order to maintain the reservoir pressure. This scenario can be interpreted as geothermal energy production using wells placed in a regular configuration. The problem is simulated with multiple interacting continua approach. Every matrix block is partitioned in four blocks for a more accurate modelling of the heat sweep. The problem is simulated for two different fractures spacing. The temperature distribution over a straight line between an injection and production well is reported.
