RIGVIS-EH is a liquid viscosifier containing high purity hydroxyethyl cellulose (HEC) suspended in a proprietary, organic, ultra-clean, environmentally safe base fluid. RIGVIS-EH is stable and will not settle or experience separation.
Typical Physical Properties
| Appearance | Tan, Opaque Liquid |
| Odor | Ether-Like |
| Density (lbs./gallon) | 1.02 – 1.06 g/ml |
| Specific Gravity @ 60°F | 8.5 |
| Flash Point | >168°F |
| pH | Neutral |
Applications
RIGVIS -EH is primarily used in water based drilling fluids or clear brine systems as a primary viscosifier to add viscosity and suspension to the fluid being treated.
Advantages
Faster yielding than dry HEC powder. Each pail contains 16 lbs of hydroxyethyl cellulose. Because of the proprietary base fluid carrier that RIG-CHEM’s RIGVIS-EH is blended in the full pail is able to be utilized when mixing and blending. Yields smooth, uniform viscosity with no lumping.
Environmental Data
When blended with completion fluids, RIGVIS-EH will pass Oil and Grease regulations. When used as directed and tested according to the U.S. Environmental Protection Agency’s Static Sheen Test, RIGVIS-EH does not form or create a sheen on the surface of receiving waters.
Treatment
For a typical treatment to obtain a Marsh funnel viscosity of 35-40 sec/qt mix 5 gallons RIGVIS-EH per 20 barrels of fluid.
Handling
Improper handling of this chemical or any other chemical deemed as an “industrial chemical” can be injurious to workers. Observe all safety precautions shown and labeled in the Safety Data Sheet.
