10. A method for forming a closed-loop geothermal well in a subterranean geothermal zone, comprising:
drilling a first open hole lateral wellbore extending out from an inlet wellbore and sloping downward into the geothermal zone, the inlet wellbore extending from the terranean surface; and
drilling, at a different depth than the first lateral wellbore, a second open hole lateral wellbore extending out from an outlet wellbore and sloping downward into the geothermal zone to intersect the first lateral wellbore at a junction, the junction being at a greater depth than a downhole end of the inlet wellbore and a downhole end of the outlet wellbore, to allow fluid to circulate from the inlet wellbore to the first lateral wellbore, from the first lateral wellbore to the second lateral wellbore, and from the second lateral wellbore to the outlet wellbore, the outlet wellbore extending from the terranean surface.
