Abstract

Summary

Naturally fractured reservoirs make up a large proportion of the planet’s hydrocarbon resources. The permeability of these reservoirs is controlled by the connectivity of the fracture network. However, it should be pointed out that the development is still poorly understood especially during hydraulic fracturing operation in oil/gas or geothermal industry. Normally, in reality very high tensile stresses are generated around the tips of fractures when the fluid pressure inside them is high enough. Fracture linkage occurs when these areas of high stress within a minimum separation distance of each other and are greater than the tensile strength of the rock.

Multi-phase fluid flow is tested in fractured reservoir analogue models to view the effect of fracture networks in the case of optimizing enhanced oil recovery (EOR) and Enhanced Geothermal System (EGS). The results show extensive connectivity of fractures is crucial for efficient penetration of the injected phase into the reservoir. Finally, flowing fluid in a fractured reservoir, fractures act as faster pathways for injected materials to travel through than the matrix.
