Polyanionic cellulose (PAC) is a water-soluble cellulose ether derivative made by chemically modifying natural cellulose. It is an important water-soluble cellulose ether. Polyanionic cellulose has important applications in offshore exploration and production, drilling and salt well operations in the upstream oil and gas industry. This product is white or light yellow odorless powder, which is hygroscopic, tasteless and non-toxic. Polyanionic cellulose can be dissolved in water at both low and high temperature, and forms a viscous liquid when dissolved in water.
Polyanionic cellulose exhibits high stability in high temperature applications and also exhibits high tolerance to the environment. It has also been found to have antibacterial properties. Polyanionic cellulose shows excellent fluid loss reduction ability, inhibition ability in various applications and higher temperature tolerance. In addition, polyanionic cellulose has a wide range of applications in various industries other than the oil and gas industry. For example, industries such as food and beverages, pharmaceuticals, chemicals, plastics, and polymers are some noteworthy end-use industries.
In the process of searching for hydrocarbons to ensure a stable, long-term supply of crude oil and natural gas, and sufficient energy, oil exploration and production companies have been formulating strategies to purchase and develop offshore oil and gas fields in deeper waters and harsh offshore environmental conditions. This has been translated into an increase in the demand for polyanionic cellulose, because polyanionic cellulose has important applications in the context of changing the properties of drilling fluids to ensure smooth operation of oilfield services. Compared with other oilfield chemicals, polyanionic cellulose provides superior filtration control and supplement viscosity in most water-based drilling fluids. This is an important factor driving the growth of the polyanionic cellulose market.
