• b. capturing at least a portion of the heat energy from the produced fluid exiting the wellbore using the energy recapture device;
• c. transferring a component of the at least a portion of the heat energy from the produced fluid exiting the wellbore to produced water entering a thermal distillation device;
• d. purifying the produced water as the water flows through the thermal distillation device by causing at least a portion of the contaminated fluid to change into a purified vapor state inside the thermal distillation device.

A system comprising:

• a. a wellbore with a wellhead attached to the wellbore;
• b. at least one energy recapture device connected to the wellhead of the wellbore with produced fluids exiting the wellhead, wherein the at least one energy recapture device captures heat energy of the produced fluids exiting the wellhead;
• c. at least one heat exchanger that uses the heat energy of the fluids exiting the wellhead to prewarm the produced water inside the at least one heat exchanger;
• and
• d. at least one thermal distillation device, wherein a portion of the produced water is heated to a purified vapor stream and wherein at least a portion of the heavier contaminated fluid is separated from the lighter purified vapor stream;
• e. at least one control panel that operates the at least one energy recapture device and the at least one thermal distillation device in a coordinated manner.
