Thermoelastic fracturing and buoyancy-driven convection – Surprising sources of longevity for EGS circulation

To maximize value from an EGS system, we need to optimize flow rate, well spacing, and well configuration. These engineering decisions will make the difference between a money loser and a cash cow. I’ve recently run ResFrac simulations of long-term EGS circulation and observed some surprising and intriguing results.
