Product Description

PAC-R LUDE TM

FILTRATION CONTROL ADDITIVE

Product Name : Polyanionic Cellulose

Product Description

PAC-R LUDEis a high quality Poly Anionic Cellulose Polymer, useful in controlling filtration and increasing rheology in all type of water, but is particularly effective in salt water brines. PAC-R LUDE additive will aid in dispersion control by attaching and encapsulating the drill solids. It may be used at all density ranges, and functions effectively in dispersed and non-dispersed systems.

Typical Physical Properties  

Ø Physical appearance        White free flowing powder  (The water solution is transparent viscous liquid)

Ø Specific gravity               1.5-1.6

Ø Solubility                         Soluble

Ø Bulk density                   500-900 kg/m3

Application

Ø Provides protection against water sensitive hydrate-able formations

Ø Improves core recovery in diamond drilling

Ø Can be used with bentonite, liquid polymer, with other porducts or as a single mud additive

Ø Can be used in fresh, brackish and salt water

Ø PAC is cost effective means of controlling fluid loss and increasing viscosity

Ø It’s a water soluble polymer

Ø Control filtration rates

Ø Provide supplementary viscosity in fresh water, sea water, and brine-based fluids

Advantages

Ø Reduces friction between the drill string and the open hole

Ø May be used in all types of water base muds and salinity

Ø Decreases torque and drag

Ø Has application in deviated and extended reach wells

Ø Has high temperature stability up up to 350 °F

Ø It is a high yield viscosifier

Ø It is resistant to ions and is effective over a wide PH range

Ø Improves shale control

Ø It is an excellent thermal stability

Ø Can be used to increase life of foam in air

Ø Resists attack from bacteria, requiring no preservatives or bactericide

Ø Effective in controlling fluid loss

Ø Environmentally acceptable

Ø Depending on water quality, provides viscosity

Packaging and Storage

PAC-R LUDE filtration control additive is packaged in 25 kgs kraft bags.

Store in a dry location away from sources of heat or ignition, and minimize dust.
