Abstract
A system for regulating fluid flow in a geothermal energy production system includes a flow control device disposed in an injector well and/or a producer well, which are disposed in a subterranean region. The injector well includes an outflow port configured to inject a fluid into the region, the producer well includes an inflow port configured to receive the fluid from the region, and the outflow port and the inflow port are in fluid communication via one or more passages in the subterranean region between the injector well and the producer well. The flow control device is configured to restrict a flow of a fluid into the producer well based on a temperature and/or a flow rate of the fluid in the flow control device. The temperature and/or the flow rate selected to maintain a temperature of the fluid entering the producer well within a selected range.
