Put simply, it is to inject tint of chemical settling agent, and its close touch with dispersed infinitesmal drill cuttings flocculate them to bigger particles and quickly settle them.

Chemical precipitation, one of the many solids control solutions, is also endowed with some unique features.

Put simply, it is to inject tint of chemical settling agent, and its close touch with dispersed infinitesmal drill cuttings flocculate them to bigger particles and quickly settle them.

And the soluble high polymer flocculating solid particles in the mud is usually called chemical floeculant. The kind that even works effectively with bentonites and drill cuttings is total floeculant, with mere application in water drilling fluids for zero solid content. However, premium bentonite is not supposed to be removed by floeculants as a useful solid phase of drilling fluids. The experts developped a selective floeculant, frequently used in non-dispersed low solids drilling fluids, solely aimed at drill cuttings and coarse bentonite rather than premium bentonites.

What is more, drill cuttings are mechanicallly and chemically fracked to particles on its way back to wellhead. Encapsulating agent encapsulates them so that the drill cuttings are kept large enough for easier mechanical and chemical removal when they get back to ground. Both encapsulating agent and floeculant are high molecular polymers. They usually are polyacrylamides, partially hydrolyzed polyacrylamides and hydrolyzed polyacrylamides(HPAM).
