Numerical simulation of heat extraction performance in enhanced geothermal system with multilateral wells
TL;DR: In this paper, an enhanced geothermal system with multilateral wells is proposed to extract heat from hot dry rock, where one main wellbore is drilled to hot dry rocks and several injection and production multilateral well are side-tracked from the main well bore in upper and lower formation, respectively.

Heat Recovery from Multiple-Fracture Enhanced Geothermal Systems: The Effect of Thermoelastic Fracture Interactions
TL;DR: In this article, the authors investigated the effect of thermoelastic interactions between multiple parallel fractures on energy production from a multiple-fracture enhanced geothermal system and showed that the matrix deformation significantly increases the interactions between the two adjacent fractures.

Non-linear regimes of fluid flow in rock fractures
TL;DR: In this paper, high-resolution Navier-Stokes simulations and laboratory measurements of fluid flow in a natural sandstone fracture were conducted, where epoxy casts were made of the two opposing fracture surfaces, and the surface profiles were then measured at a vertical resolution of ±2 μm, every 20 μm in the x and y-directions, over 2 cm × 2 cm regions of the fracture.
