Suspending Agent Suspending agent is used to prevent the settling of the fines and particles during an acidizing operation. | Surface Tension Reducer Surface tension reducers are used to lower the surface tension and the interfacial tension between immiscible fluids and also leave the reservoir rock water wet. | Corrosion Inhibitor corrosion inhibitors protect metals by slowing down the rate of corrosion. It is used in different types of acidizing designs to protect various equipment from corrosion. | ||
Viscoelastic Surfactant (VES) It is a chemical diversion method. To divert the acid toward low permeable zones in the formation, VES is used as a diverter to improve the quality of an acid operation. | Clay Stabilizer Clay stabilizers are used to mitigate the swelling and migration of clay minerals to prevent the pore throats from plugging. | Iron Control Agent An iron control agent is used to prevent the precipitation of iron during an acidizing operation. since precipitation of iron causes plugging in the reservoir, using an iron control additive can prevent this failure. | ||
Foaming Agent Foaming agents are used to increase the production rate of a well in different well stimulation operations. | NonEmulsifier NonEmulsifiers are used to prevent emulsion formation between acid and reservoir hydrocarbon. | AntiSludge Agent An Antisludge agent is used to prevent or eliminate the formation of sludge when acid comes in contact with oil during an acidizing operation. | ||
H2S scavenger This additive is used in acidizing designs to remove or reduce the level of H2S produced during an acidizing operation. | Acid Retarder Acid retarders are used to reduce the reaction rate of acid with reservoir rock. | Iron Reducer Agent An iron reducer agent is used to reduce the ferric ion to ferrous ion to prevent the related damage during acid operations. | ||
Corrosion Inhibitor Intensifier This additive is used as an auxiliary additive along with the corrosion inhibitor additive at temperatures above 200 ˚f to reduce the corrosion rate. |
