Abstract

Methods for treating water comprising dissolved solids in a wellbore include injecting water into a wellbore, where the wellbore has a depth that is sufficient for introducing a hydrostatic pressure that imparts supercritical pressure to water present at a water depth greater than or equal to the minimum depth needed to impart water supercritical pressure. A heating element is inserted into the wellbore to a heating element depth that is greater than or equal to the required depth. Power is transmitted to the heating element causing the heating element to heat water to a temperature sufficient to form supercritical water that causes the dissolved solids to precipitate out of the water as precipitated solids. Water and the precipitated solids are separated and extracted. The heating element includes a microwave antenna and a shell encapsulating the microwave antenna formed from a material that is capable of heating upon exposure to microwave radiation.
