NOVATEC F

Filtration-control additive

NOVATEC F additive is a maleated rosin polymer glycol ether used as a fluid-loss reducer in the NOVATEC synthetic drilling fluid system.

NOVATEC F additive is also effective in reducing filtration properties in synthetic paraffin- and mineral-oil-based systems.

Typical Physical Properties
Physical appearance	Dark-brown liquid
Specific gravity	1.01
Solubility	Insoluble in water
Flash point	>167 degF [>75 degC]
Viscosity, cP at 77 degF [25 degC]	129
Boiling point (760-mm Hg)	356 degF [180 degC]
Freezing point	23 degF [–5 degC]

Applications

NOVATEC F additive is used to provide supplementary fluid-loss control in the NOVATEC system, normally at high oil/water ratios and at temperatures >300 degF [>149 degC]. Treatment levels required depend on the desired filtration control, the brine ratio and density of the drilling fluid but will typically be in the range of 0.33 to 0.85 gal/bbl [8 to 20 L/m³]. Pilot testing to determine necessary concentration is recommended.

Advantages

Imparts rapid reduction in HPHT filtration when used at relatively low concentration levels
Stable to high temperatures >400 degF [>204 degC]
Effective in a wide range of synthetic fluids including olefin and paraffin-base systems, as well as mineral-oil-base drilling fluids

Toxicity and handling

Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions described in the safety data sheet.

Packaging and storage

NOVATEC F additive is packaged in 55-galUS [208-L] steel drums with 195-kg net weight. Store in a tightly closed original container in a cool, dry, and well-ventilated place.
