Efficient Numerical Simulation of Nonequilibrium Mass and Heat Transfer in Fractured Geothermal Reservoirs
Transient heat andor fluid mass exchange between the permeable fracture system and the surrounding relatively impermeable country rock can be treated in geothermal reservoir simulators using the “MINC” technique. This approach typically requires about an order of magnitude more computer time than the analogous “porous medium” problem. Under practical conditions, the problem can often be lineari...
متن کاملHeterogeneity Preserving Upscaling for Heat Transport in Fractured Geothermal Reservoirs
In simulation of fluid injection in fractured geothermal reservoirs, the characteristics of the physical processes are severely affected by the local occurence of connected fractures. To resolve these structurally dominated processes, there is a need to develop discretization strategies that also limit computational effort. In this paper we present an upscaling methodology for geothermal heat t...
متن کاملInverse Modeling of Fractured Geothermal Reservoirs Using Pressure Interference Data
Numerically inverting simultaneous pressureinterference measurements from multiple observation wells can help to establish the large-scale spatial distributions of permeability and storage within a geothermal reservoir. For realistic results, it is important to incorporate double-porosity (MINC) descriptions into the modeling process to properly reproduce the short-term pressure-transient respo...
متن کاملAn Integrated Modeling Approach for Characterizing Multiphase Flow, Chemical Transport, and Heat Transfer in Fractured Reservoirs
Even with the significant progress made in modeling flow and transport in fractured rock in the last few decades, characterizing fractured reservoirs remains a great challenge. This is because of the inherent complexity within actual fractured reservoirs, from multiphase flow and transport to the spatial variability of the fracture network. To investigate coupled processes of fluid and heat flo...
متن کاملFoam Application in Fractured Carbonate Reservoirs: A Simulation Study
Fractured carbonate reservoirs account for 25% of world’s total oil resources and for 90% of Iranian oil reserves. Since calcite and dolomite minerals are oil wet, gas oil gravity drainage (GOGD) is known as the most influencing production mechanism. The most important issue within gas injection into fractured media is the channeling problem which makes the efficiency of gas injection process e...
