  • Patent number: 12663008
    Abstract: Systems and methods provided herein relate to a well site or other plant. Systems and methods are employed to determine fouling and/or reduce maintenance and down time associated with equipment that is subject to fouling conditions due to their operating environments in some embodiments. Fouling can include but is not limited to scale formation due to mechanical, thermal, chemical or combinations of such phenomenon. These phenomenon are initiated and progressively exacerbated as the equipment interacts with gaseous, solids and/or liquids from the operating environment. The equipment includes stationary and rotary equipment including but not limited to pump systems, valves, piping, heat exchangers, and plumbing utilized to move fluid in a well in a subterranean environment.
