Polymer materials are used for sealing purposes in gas and oil wells. Material choice is critical in order to stand the environment a well represent with high differential pressure, high temperatures and chemical aggresive environment.

In industry several companies have specialised on sealing off the annulus by injection of a thermoset resin with sutaible viscosity and curing properties. Some companies have developed dedicated tools which enables transportation of resin, perforation and injection in one procedure.

• Material selection
• Design of sealants
• Choice of resin and curing system
• Stability and lifetime
• Design of flow properties
• Prediction of temperature profiles
• Estimate risk for runaway
