With the gradual depletion of oil wells operable at relatively lower temperatures and pressures, the upstream oil industry relies on High Pressure High Temperature (HPHT) wells to source crude oil and gas. HPHT well extraction and processing require anticorrosive coatings applied on substrates such as downhole piping and pressure vessels that can withstand such temperature and pressures.
Very little information is available regarding the degradation mechanisms of currently used solvent-borne epoxy coatings in these conditions. Cyclic stress tests at lower temperatures (25-85 °C) [I] resulted in coating fractures and holes from collapsed blisters originatingfrom thermal shocks.
