The primary types of Oilfield Stimulation Chemicals are acidizing chemicals, fracturing fluids, and drilling muds. Acidizing chemicals are used to dissolve and remove materials that clog the pores of the reservoir and restrict the flow of oil and gas. Acidizing is typically used in carbonate reservoirs, where the rock is soluble in acid. Fracturing fluids are used to create fractures in the rock formation to allow for better flow of oil and gas.

Drilling muds are used during the drilling process to cool the drill bit, lift rock cuttings to the surface, and provide a barrier to prevent the wellbore from collapsing. The use of Oilfield Stimulation Chemicals can have environmental implications, and as such, regulatory bodies such as the Environmental Protection Agency (EPA) in the United States have set guidelines for the use and disposal of these chemicals. The disposal of oilfield stimulation chemicals is an important issue, and companies in the oil and gas industry must follow strict guidelines to prevent environmental damage.
