ABSTRACT:
A solids composition based on clay minerals and consisting of a) 40-99.8 wt. % of a clay mineral with a reduced moisture content of .ltoreq.7 wt. %, b) 0.01-30 wt. % of a mixed metal hydroxide and c) 0.01-30 wt. % of a solid base, and if necessary other additives, is described. The solids composition of the invention is an easy-to-use thickening agent for water-based drilling fluids, and has a long-term stability of at least three months.
