Coal phosphate additive RS-810
Coal phosphate additive RS-810

Coal phosphate additive RS-810 is a modified humate reagent of dispersing and general improving action for water-based drilling muds. Helps stabilize rheological properties and reduce the fluid loss of water-based drilling fluids in difficult downhole conditions (abnormally high pressure, high temperature).

Scope of use and application
RS-810 is used to regulate processing characteristics of water-based clay drilling fluids, mainly when drilling the upper intervals composed of mud shales actively passing into drilling mud. Effectively reduces rheology and filtration in fluids with high mud-betonite test index. The product demonstrated very good results in improving the quality of cementing when used as part of detergent separation buffers during well cementation.
Drilling muds 0,2–1,5 %
Cement slurries (setting retardation) 0,1–0,3 %
Buffer solutions 5–7 %
Toxicity and handling requirements
Presents no danger. Non-toxic. In terms of the degree of impact on the human body, according GOST 12.1.007 RS-810 belongs to the 4th class of hazard and toxicity (low-hazard substances)
Packaging and storage
RS-810 (UVR) is supplied in multilayer moisture-proof paper bags with a capacity of 20 - 50 kg.
Store away from direct sunlight and sources of heat with temperature over 60°С.
