Denver SPE General Meeting: From Heel to Toe: Engineering Uniform EGS Injection
Abstract: EGS circulates cooler water through hydraulically connected horizontal wells, creating a subsurface heat exchanger. Ideally, the injection is evenly distributed across the fracture network to promote uniform thermal drawdown; however, fracture variability and wellbore friction can concentrate flow in high-conductivity pathways or heel-biased stages, reducing sweep efficiency and accelerating thermal breakthrough. Modeling indicates conformance […]
