Polyanionic cellulose (PAC) is a water-soluble polymer that is derived from cellulose, which is a natural polymer found in plants. PAC is commonly used as a drilling fluid additive in the oil and gas industry due to its unique properties, which help to improve the performance and efficiency of drilling operations.
PAC is a highly effective fluid-loss control agent, which means it helps to prevent the drilling fluid from leaking into the formation and damaging the wellbore. PAC achieves this by forming a thin, impermeable filter cake on the walls of the wellbore, which helps to prevent fluid loss and maintain wellbore stability.
In addition to its fluid-loss control properties, PAC also acts as a rheology modifier, which means it helps to control the viscosity and flow properties of the drilling fluid. PAC can help to increase the viscosity of the drilling fluid, which helps to suspend cuttings and prevent them from settling at the bottom of the well.
PAC is available in various grades and forms, including low, medium, and high viscosity grades, and can be used in both freshwater and saltwater drilling fluids. PAC is typically added to the drilling fluid at concentrations of 0.1 to 2% by weight, depending on the specific drilling conditions and requirements.

Overall, PAC is a highly effective drilling fluid additive that helps to improve the performance and efficiency of drilling operations by controlling fluid loss and maintaining wellbore stability. The use of PAC can help to reduce drilling costs, minimize formation damage, and improve well productivity in the oil and gas industry.
PAC is added to drilling fluids to control the fluid properties and prevent damage to the wellbore during drilling. Some of the benefits of using PAC in drilling fluids include:
Fluid loss control: PAC is highly effective in controlling fluid loss in drilling fluids, which is important in preventing damage to the formation and maintaining wellbore stability. PAC forms a thin, impermeable filter cake on the wellbore walls that helps to prevent fluid loss and maintain wellbore pressure.
Rheology control: PAC acts as a rheology modifier in drilling fluids, helping to control the viscosity and flow properties of the fluid. PAC can increase the viscosity of the drilling fluid, which helps to suspend cuttings and prevent them from settling at the bottom of the well.
Compatibility with other additives: It is compatible with a wide range of other drilling fluid additives, including salts, emulsifiers, and other polymers. This makes it a versatile additive that can be used in a variety of drilling applications.
Temperature and salinity stability:Is stable at high temperatures and in high-salinity environments, which makes it suitable for use in a variety of drilling applications.
Environmentally friendly: A biodegradable and renewable resource that is environmentally friendly and poses no threat to the environment.
Overall, PAC is an effective drilling fluid additive that helps to control fluid loss, maintain wellbore stability, and improve drilling efficiency. Its versatility and compatibility with other additives make it a popular choice in the oil and gas industry for a variety of drilling applications.
Adding PAC can prevent any dangerous situation (being blocked or collapsing) in production process by making this fluid stiffer.
Because of its low water loss properties PAC work-over fluid can reduce water that goes into productive zone, and the water that enters into productive
The benefits of PAC polyanionic cellulose work-over provides more than any other same products do: Avoid any damage from productive zone during process, clean drill hole and reduce maintenance to drill hole; Block filtration of water and mud and cause less bubbling; Store or can be used from one well to another, with lower cost than that of any other same products.
