... production wells to be considered. The continuity equation for the flow of an incompressible Newtonian fluid in the fracture plane is expressed as ( ) 1 , , N f j j j j Q x x y yd = Ñ = - -ågq (2) where · is the divergence operator, denotes the Dirac delta function, Q j is flow rate into or out...

... diameter may be drilled into the sample while at reservoir conditions. This allows for simulation of borehole damage as well as injector-producer schemes. Dual 70 MPa syringe pumps set to flow rates between 10 nL/min and 60 mL/min injecting into a partially cased borehole allow for fully contained...

... process is repeated several times maintaining the same flow rate. The magnitudes of the principal stresses are calculated from the various pres sure readings. Normally only pure water is used and pressures are typically a maximum of 6,000 psi but can be as high at 15,000 psi. Flow rates are low at about...

... to support the required high geothermal flow rates. Performance will be significantly impaired if the average fracture separation is greater than 50 meters or so. The crea tion of such extensive and pervasive artificial fracture networks at costs that will prove acceptable is the fundamental challenge...

... temperature gradients. Although the crystalline basement is not completely impermeable due to the presence of open fissures, fractures, or faults its overall permeability is generally far too low to achieve and maintain production flow rates sufficient for geothermal power production. The majority...

... the fracture interaction in a complex fracture model such as UFM. A new crossing model, called OpenT, taking into account the effect of flow rate and fluid viscosity on the hydraulic/natural fracture crossing behaviour is integrated in UFM simulator. The previous fracture crossing model is primarily based...
