Abstract
A method including forming a hydrophobic film on one or more surfaces as part of a geothermal operation in which a circulating fluid comprising water is injected into an injection well, absorbs heat, and is recovered from a production well prior to extraction of at least a portion of the heat therefrom and recycle of the circulating fluid back to the or another injection well.
