High-temperature stabilizers

Linear gel may dehydrate due to exposure to high-temperature, causing a loss of viscosity and risk of screen-out – cessation of pumping due to loss of fracture width which causes a spike in the treating pressure. Screen-outs can be dangerous, and operationally challenging and time consuming to remediate.  Stabilizers are therefore required at temperatures greater than 200°F, or approximately 95°C. Special compounds have been developed for this specific purpose, and should be tested with the fluid system to ensure correct concentrations are used during the treatment. Compatibility and performance should also be tested with any breakers in the fluid system.
