IMPROVED GAS MIGRATION CONTROL IN OIL WELL CEMENT

Polymers are being used as multifunctional additives that control fluid loss, free water and prevent gas migration through cement slurry. Most ofthe polymers degrade at 80 °C and lose their viscosity with increasing temperature. The reduction in the viscosity of polymers leads to fluid loss, free...
