Numerical simulation of flow heterogeneities within a real rough fracture and its transmissivity

Core analysis studies the fractures characteristics and explains the fluid-rock interactions to provide the information of permeability of a reservoir or an enhanced geothermal system (EGS). This study presents a numerical simulation of flow through a single fracture of an experimented core of an EGS. The injection pressure plots with respect to injection flow rate were compared with available experimental results. The transmissivity of the fracture was evaluated and compared to the experimental measurements. All results indicated good agreements with corresponding experimental results and showed the efficiency of numerical methods to determine the transmissivity of single fractures.
