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 %
