1. An apparatus to be positioned in a geothermal wellbore formed in a subsurface formation, the apparatus comprising:
one or more components to inject a supercritical fluid into the subsurface formation; and
a flow control assembly positioned at a first downhole location in the geothermal wellbore and configured with one or more electronically controlled components to control flow of the supercritical fluid into the geothermal wellbore from the subsurface formation at the first downhole location based on a density of the supercritical fluid in the subsurface formation proximate the first downhole location, wherein the flow control assembly is configured with one or more sensors to measure the density, and wherein the one or more electronically controlled components are configured to remain at least partially open to continuously detect the density of the supercritical fluid in the subsurface formation.
