COATING COMPOSITIONS FOR EROSION MITIGATION, AND COATED COMPONENTS AND METHODS USING SAID COATINGS
A method to transmit produced fluids in a system configured to recover hydrocarbons from a subterranean formation includes directing produced fluids through a pipe having a coating on its internal surface. The coating includes: a first polymeric layer on the internal surface, the first polymeric layer including a first viscoelastic material and having a hardness between 30 Shore A and 90 Shore D; a second polymeric layer between the internal surface and the first polymeric layer, the second polymeric layer including a second viscoelastic material stiffer than the first viscoelastic material; and a protective layer on the first polymeric layer and having a different composition than the first and second polymeric layers. The protective layer includes a plurality of particles having a Mohs hardness equal to or greater than 7. The method includes dissipating, via the first polymeric layer, forces from erodent materials in the produced fluids impacting the coating.
