Biocides are oil and gas chemicals used to prevent the growth of bacteria, fungi, and other microorganisms that can contaminate oil and gas. Biocides are used in various processes, including drilling, production, and refining. These chemicals work by disrupting the metabolism of microorganisms or destroying their cell membranes. Biocides are typically composed of quaternary ammonium compounds, isothiazolinones, or chlorine-based compounds.

Demulsifiers, also known as emulsion breakers, are Oil and Gas Chemicals used to separate oil and water emulsions. Emulsions occur when water becomes trapped in oil, forming a stable mixture. Demulsifiers work by breaking the bonds between the water and oil molecules, allowing the two substances to separate. Demulsifiers are commonly used in the production and refining processes.
