Abstract
A new EGS arrangement, Robust EGS (REGS), is studied for its potential benefits for wide-spread applications for clean, carbon-free, electrical energy generation. Numerical simulations are carried out to prove the key benefit of REGS in a simple, but effective, geologic heat exchanger arrangement with large, stabilized fracture aperture and controlled flow zones. The numerical model results show the estimated potential energy capacity and the converted value to electrical energy generation over a 30-year operation time period for two simple REGS arrangements. The results may assist EGS investors and drilling companies in deciding whether the investment and operation can be made profitable for the wide-scale application of REGS for green energy generation.

This study presents a low-cost, numerical simulations is to show the energy extraction and monetary benefits of a si Robust EGS (REGS) arrangement that requires only two, directionally drilled, deep wells
The fluid temperature variation at the exit point of each planar fracture is shown in Figure 7 with time through the twin REGS circulation loop from downwell D1 through seven REGS fractures from
