High-performance coatings from poly(arylene sulfide) resins
Poly(arylene sulfide) resins have been formulated as high-performance coatings and applied to steel pony rods for laboratory and oil well testing. The performance of the poly(arylene sulfide)-based coatings was evaluated as a measure of their ability to reduce corrosion in producing but highly corrosive wells, by comparison to commercial epoxy coated pony rods. A high-pressure testing apparatus was built in the laboratory to simulate downhole oil well conditions, and it was used as a screening device to select coatings for field trials. Poly(phenylene sulfide) resins of 17,700 weight average molecular weight were cured to form coatings on pony rods. These rods, installed in two wells, have survived for eight months without any measurable deterioration of the coating. Epoxy and higher molecular weight coatings of poly(phenylene sulfide) exhibited varying degrees of deterioration after five months.
