Thickeners are used to increase the viscosity and density of drilling fluid, usually including clay and starch. Clay is generally used to prepare mud, and starch is mainly used to prepare starch slurry.
Carboxymethyl cellulose (CMC) or cellulose gum is a cellulose derivative with carboxymethyl group in its chain. CMC is a physiologically inert, chemically stable, odorless and tasteless substance which safe for health and environment. The other properties
PAC and CMC are used in oil drilling fluids and completion fluids. In drilling fluids, it works as viscosifier, flowing controller and filtration reducer, with strong suspending capability, high ability of carrying crumbs.
drilling fluids : types, composition & uses
drilling fluid
Drilling fluids, also known as drilling muds, play a crucial role in the oil and gas exploration process. These specialized fluids serve multiple purposes.
Polyaluminium Chloride(PAC) Water Treatment, What is PAC？Polyaluminium Chloride(PAC) is a chemical commonly used in the field of water treatment. It is a highly effective flocculant made by aluminium salts with aluminium chloride.
Coagulants: Such as aluminum sulfate, polyaluminum chloride (PAC), and ferric chloride, used to destabilize and aggregate suspended particles.
Flocculants: Polymers like polyacrylamide (PAM) that help form larger flocs from coagulated particles.
