Formation permeability can be compromised by sludge deposits. SBL’s anti-sludge agents inhibit the formation of sludge and emulsions that can occur during acidizing operations. During these operations, certain acids such as HCI acid solutions encounter crude oils. It is when the acid reacts to the oil that dense, asphaltene sludge deposits can form. SBL’s anti-sludge agents work to prevent sludge formation, maintain formation permeability, and promotes rapid return of the treating fluid to the wellbore.
