Geothermal Plays – Convection Dominated

Continuing the series, here is Part 2 of 7 about Convection Dominated Geothermal plays. In this case there is an upflow of fluids transporting heat from depth to shallower reservoirs (or the surface). Probably more well known than some other plays since the majority of operating Geothermal power plants are utilising these kinds of play. But as you will see in the next part, not all plays require magmatic or plutonic rock.

“…upflow of fluids transporting heat from depth to shallower reservoirs (or the surface)…”

The majority of current operating Geothermal power plants are utilising convection-dominated play systems to successfully access heat resources.

For the plays shown, there are not necessarily always surface manifestations (“Blind Geothermal”)
