Lignite-HMTA Thinning Agent (Drilling Fluid)
Causticized lignite treated with hexamethylenetetramine (HMTA) used as a classic thinning and deflocculant agent for freshwater and saltwater water-based drilling muds. Effectively reduces plastic viscosity and yield point at elevated temperatures, maintaining optimal rheology during deep drilling operations. Performs within a pH 9–11 operating range.
