... (ACGS) has been proposed to enhance heat production in this research. The ACGS incorporates a hydraulic fracture, partitioned by a horizontal insulator for vertical zonal isolation of fluid flow in the fracture, into the closed-loop system's fluid circulation. Since working fluid flows through...

Modeling of the fluid flow is subdivided into two parts: fluid flow through the proppant pack near the perforation, and fluid flow through the perforation into the wellbore. The proppant pack is described as a set...
