Finely ground dried bentonites were compacted with a laboratory size Komarek roller compactor. Before compaction the moisture content of the bentonite was adjusted from 8-12% by adding water in a mixer. Predetermined amounts of Nat CO3 activator were dissolved in that water and added to the bentonite. Comparative rheological tests were then run with the compacted, activated bentonite versus unaltered bentonite. Compaction and activation of the bentonites improved their viscosity and water loss properties considerably, more so than extrusion and slurrying. It was concluded that, by using a compactor, bentonite reserves can be extended because low quality material can be improved without adding organic polymers. Introduction Many bentonites mined in Wyoming, South Dakota, and Montana are naturally of drilling mud quality. Those of low sodium content, and those of predominantly potassium, calcium, and magnesium exchangeable cations need altering to meet drilling mud requirements. Most foreign bentonites require sodium activation to meet drilling mud standards set by the American Petroleum Institute (API).
