Low Viscosity Polyanionic Cellulose PAC LV Chemical Additive Best Price for Water Based Drilling Mud System API-Specification 13A

Product Description

Polyanionic Cellulose (PAC)

PAC is a high-performance, water-soluble cellulose ether, typically available as its sodium salt. It is a premium polymer derived from natural cellulose through sophisticated chemical modification. This anionic polymer is widely recognized in the oil and gas industry as an indispensable additive for water-based drilling fluid systems.

PAC is primarily used to control filtration rates, optimize rheology, and manage solids behavior in drilling fluids, ensuring efficient and stable operations. It exhibits unique and valuable properties including excellent salt tolerance, high-temperature stability (up to 300°F / ~150°C), and shear-thinning behavior, making it essential for challenging drilling conditions such as deep wells, high-salinity formations, and offshore operations.

Key Features

PAC-HV (High Viscosity): Designed to provide supplementary viscosity and enhance rheological properties, improving hole cleaning and suspension of cuttings.

PAC-LV (Low Viscosity):  Engineered for effective fluid loss control with a minimal increase in system rheology, making it ideal for solids-laden fluids.

As a versatile and environmentally compatible solution, PAC helps improve wellbore stability, reduce formation damage, and enhance the overall efficiency of drilling operations.

Key Features

Benefits

Superior Fluid Loss Control: Effectively reduces the amount of liquid escaping from the drilling fluid into the formation, forming a thin, tough, and low-permeability filter cake that minimizes differential sticking and formation damage.

Excellent Rheology Modification: Acts as an effective viscosifier, providing excellent suspension properties to carry drill cuttings to the surface and improve hole cleaning.

High Salt & Thermal Tolerance: Maintains stable performance in fresh water, seawater, and saturated brine, and can withstand high downhole temperatures up to 300°F (~150°C).

Non-Fermenting & Biocide-Free: Does not require a biocide for preservation, as it resists bacterial degradation, ensuring long-term fluid stability.

Environmentally Compatible: Non-toxic and biodegradable, aligning with modern environmental standards for drilling operations.

Cost-Effective: Provides high-performance characteristics at a low dosage, often requiring only 30-50% of the dosage compared to CMC, offering significant cost savings

Applications

Packaging & Storage

Drilling Fluids: As a primary additive in water-based muds (WBM) for viscosity and filtration control.

Completion & Workover Fluids: To control fluid loss and suspend solids in completion and workover operations.

Fracturing Fluids: Used as a fluid loss additive and to help suspend proppants.

Packaging: 25 kg net weight in multi-wall kraft paper bags with an inner PE liner, palletized for export.

Storage: Store in a cool, dry, well-ventilated area, away from direct sunlight and moisture.

Shelf Life: 24 months from the date of manufacture under proper storage conditions.

FAQ

Q1. What is the difference between PAC-HV and PAC-LV?

A: PAC-HV (High Viscosity) is designed to increase mud viscosity and improve hole cleaning, while PAC-LV (Low Viscosity) provides effective fluid loss control with minimal impact on rheology. Choose based on your specific drilling fluid requirements.

Q2. Is PAC suitable for saltwater and high-temperature drilling?

A: Yes. Our PAC products exhibit excellent salt tolerance (fresh water, seawater, and saturated brine) and thermal stability up to 300°F (~150°C), making them ideal for deep wells and offshore drilling operations.

Q3. How does PAC compare to CMC in drilling fluids?

A: PAC offers higher purity, better salt tolerance, and more stable viscosity compared to CMC. It also requires lower dosage (typically 30-50% less than CMC) to achieve similar performance, providing significant cost savings.

Q4. What is the standard packaging and shelf life?

A: PAC is supplied in 25kg multi-wall kraft paper bags with inner PE liner, palletized for export. Shelf life is 24 months when stored in a cool, dry, and well-ventilated area away from moisture.

Q5. Can you provide samples for testing?

A: Yes. We offer free samples for quality evaluation (sample cost waived, freight to be borne by the buyer). TDS, COA, and MSDS are available upon request.
