Gas Migration Control Additives

 Gas control/anti-gas migration additives are used to reduce the risk of gas invading the cement and migrating into the wellbore. Cement slurries with oil and gas typically have serious problems as it causes failures for completing primary cement jobs during well completion. These well integrity failures include inadequate bonding, excessive setting of particles, and water separation. Petrochem offers three types of gas migration control cement additives with multiple advantages for slurries including controlling salt concentrated batches, preventing false setting due to pre-gelation, and enhancing shear bond strength.
