Thermoset Resins
Performance criteria to consider when selecting thermoset resins for zonal isolation applications.
Volume changes during setting
An article explaining the chemical shrinkage that occurs during the curing or crosslinking of thermoset resins, and the implications for zonal isolation.
The importance of thermal properties
When resin systems cure significant heat is liberated in a relatively short time which can led to a significant increase in temperature of the resin and surrounding material (casing, cement, rock). This increase in temperature combined with the fact that the thermal expansion coefficient of thermoset resins is much higher (>4x) than that of steel or rock may lead to loss of zonal isolation.
