We are Chrome Lignite manufacturer in India and Causticize lignite manufacture in India.
UNIVERSAL offers a line of thinners and dispersants that are specially designed to modify the relationship between the viscosity and percentage of solids in drilling fluids. Moreover, as a Chrome Lignite manufacturer in India and also Causticize lignite manufacture in India, UNIVERSAL provides thinners for most water, oil, and synthetic-based drilling fluids.
CHROME LIGNITE ( UNI-RV)
UNI-RV is a specially formulated product designed for use as a thinner, fluid stabilizer and fluid loss reducing agent in all water-base muds. To add, it is an excellent additive for HTHP filtration control and rheological stabilization for muds subjected to high temperatures.
Applications
UNI-RV agent is used in water base muds to reduce viscosity, increase rheological stability and improve filtration control. Furthermore, the effect of UNI-RV is most dramatic in fluids exposed to higher temperatures. UNI-RV can be applied to muds of any salinity, from fresh to saturated salt, as well as to lime and gyp muds. Moreover, for saturated salt or low pH mud systems, presolubilize UNI-RV in a lower salinity, high pH fluid
Physical Properties
- Physical appearance: Black, free-flowing powder
- Moisture: 10%
- Solubility in Water: 55% Minimum
- Complexed chromium content (%) : 1.00 Minimum
- Particle size Fraction (60MESH) : 15% Min. retained
- pH (2% Saln.): 9.0-10.5
- Specific gravity: 1.70@ (20°C)
Advantage
- Compatible with all water-based mud systems
- Reduces differential pressure sticking tendencies by reducing filter cake thickness and HTHP fluid loss
- Stabilizes the fluid loss and rheology of water-base muds at temperatures up to 450° F(232°C)
- Performance is not adversely affected by mud contaminants
- Particularly effective in freshwater and seawater mud systems
- An economical sodium hydroxide neutralized, UNI-RV product designed for exceptional high-temperature performance
- Contains the more acceptable Cr+³ chrome valence state
Recommended Treatment
UNI-RV may be added to the system through the mixing hopper. Depending on viscosity and fluid loss requirements, 1 to 6 lb/bbl (2.85to 17.1 kg/m³) may be required. Improved HTHP filtration control and rheological stability under adverse conditions, such as high temperatures, however, may require greater concentrations. Furthermore, for improved mud system and product performance, the pH should be maintained at 9.5 or greater.
Mud Performance
Limitations
- Most effective in alkaline systems with a pH of 9.5 or above
- Contains chrome which may not be acceptable for all applications, depending on local environmental regulations and considerations
