Abstract
A method for heating/removing and/or preventing solids in onshore or subsea pipe or wellbore tubular includes pumping a solution or suspension containing carbon nanotubes (CNT) and/or CNT based derivatives into the pipe or wellbore to a position proximate the solids and applying electromagnetic energy or electric current at one or more selected frequencies to the pipe proximate the solution. The pipe or wellbore tubular itself may be pre-coated with carbon nanotube containing material and exposed to radio frequency energy, microwaves, and electric current upon formation of solids therein.
