Weighting agents let operators alter slurry density to restrain high formation pressures and improve mud displacement. Weighting agents also play important roles in preventing strength retrogression, decreasing cement-system permeability and helping to control settling and gelation.

Here are product sheets and MSDS sheets for weighting agents for key chemicals.
