Chemicals play a vital role in the petroleum industry, particularly in the extraction and production processes.Polymers: Various polymers, such as polyacrylamide (PAM), are used as drilling fluid additives to control viscosity, improve fluid loss control, and enhance wellbore stability.Polyacrylamide (PAM) is commonly used as a friction reducer in hydraulic fracturing operations. It reduces the friction between the fracturing fluid and the wellbore, allowing for more efficient fluid flow and enhanced oil and gas production.Polyacrylamide (PAM) is also used as Enhanced Oil Recovery (EOR) Chemicals,used in polymer flooding operations to increase the viscosity of injected water, improving sweep efficiency and displacing more oil from reservoirs.
