Sodium carboxymethyl cellulose acts as binder, dispersant and thickener in battery industry. It can stabilize the structure of pole piece. Prevent sediment of active substances, improve performances of charging and discharging.

PAC R

Viscosifier - Filtrate Control Additive

PAC-R is a modified natural polyanionic cellulosic polymer (PAC). It is exhibits high viscosity and is readily dispersible and water soluble. PAC-R provides filtration control in bentonite-based drilling fluids and increases water absorption capacity. Optimal results will be obtained by using PAC-R as an additive to the Phrikolat sodium Bentonite Type W.

Applications:

Horizontal Directional Drilling (HDD), Water Well Drilling, Vertical & Oil Field Drilling, Pipe Jacking

Properties:

• Improves filter cake properties of bentonite muds
• Provides filtration control in fresh or salt water muds
• Increases water absorption capacity
• Improves flow properties of most drilling fluids
• Minimizes torque and circulating pressure
• Acts as protective colloid for bentonite
• Reduces swelling and dispersion of drilled clay/cuttings
• Promotes bore hole stability in water sensitive formations
• Effective in small quantities
• No biocides or preservatives required

PAC-R is compatible with all bentonites & additives and does not contain any harmful ingredients.

Recommended Concentrations:

Added to bentonite muds: 0,5-1 kg/m³

To stabilize Water sensitive formations: 2-4 kg/m³

Using a high shear jet-type mixer (venturi) is highly recommended. PAC-R should always be added to the system after bentonite. Adding should be done slowly and uniformly to the entire circulating system. Salt water may require twice as much PAC-R as fresh water.

Packaging:

FQA on drilling fluid additives

Q1: What are drilling fluid additives?

A1: Drilling fluid additives are chemicals used in drilling operations. They are mainly used to improve the performance of drilling fluids to meet various needs during the drilling process.

Q2: What types of drilling fluid additives are there?

A2: Drilling fluid additives can be mainly divided into the following categories:

Thickener: used to increase the viscosity of drilling fluid so that it has good suspension and carrying capabilities.

Fluid loss reducer: used to reduce the fluid loss of drilling fluid and improve its ability to seal and protect oil and gas layers.

Flow pattern regulator: used to adjust the flow pattern of drilling fluid to make it have better fluidity and sand carrying capacity.

Density regulator: used to adjust the density of drilling fluid to control the fluid column pressure in the wellbore.

Inhibitors: Used to suppress harmful ions and chemicals in drilling fluids to prevent them from causing damage to oil and gas formations.

Degassing agent: used to remove gas from drilling fluid to prevent gas invasion from affecting drilling operations.

Emulsifier: used to improve the emulsifying properties of drilling fluid so that it can pass through the oil-water interface smoothly.

Plugging agent: Used to plug lost oil and gas layers and protect them from damage by drilling fluid.

Q3: What is the function of drilling fluid additives?

A3: The main function of drilling fluid additives is to improve the performance of drilling fluid to meet the needs of drilling operations. Specifically, drilling fluid additives can improve the rheology, inhibition, lubricity, suspension, and plugging properties of drilling fluids to meet various requirements during drilling operations.

Q4: What are the application ranges of drilling fluid additives?

A4: Drilling fluid additives are widely used in various drilling operations, including oil and gas field exploration, development, production, and abandonment stages. Drilling fluid additives can be applied to oil and gas fields of different types and sizes, such as onshore, offshore, shallow, deep, vertical, and inclined wells, etc. In addition, drilling fluid additives can also be used in the development of unconventional oil and gas resources, such as shale gas, coalbed methane, flammable ice, etc.

Q5: What matters should be paid attention to in the production and storage of drilling fluid additives?

A5: The following matters should be paid attention to in the production and storage of drilling fluid additives:

During the production process, attention should be paid to the order in which chemicals are added and how they are mixed to ensure product quality and stability.

Relevant safety regulations and environmental protection requirements should be strictly observed during production and use to ensure the safety of personnel and the environment.

The storage place should be dry and well-ventilated to avoid the impact of sunlight, high temperature, humidity and other adverse conditions on the product.

Severe vibration and impact should be avoided during transportation and use to avoid damage to the product.

The site should be cleaned up promptly after use to avoid environmental pollution.
