Abstract

See full text

A geothermal well includes a borehole formed in a geologic formation. The borehole includes a first portion extending from a first end to a second end and a second portion intersecting the first portion at a first depth. The second portion is exposed to the formation for heating a fluid flowing in the second portion. The well includes an outer string disposed in the first portion where a lower end of the outer string is disposed above the first depth. The well includes an inner string disposed though the outer string and an annulus formed between the inner string and the outer string. The well includes a choke fluidly coupled to at least one of the annulus or the inner string. The choke is configured to regulate return flow of the heated fluid to maintain surface backpressure above a boiling pressure of the heated fluid at surface.
