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.
