Metals in Drilling Muds and Cuttings CONTROL DRILLING SOLIDS

May 31, 2018· Nearly all the barium in drilling mud is from barite (BaSO4) added to the mud to increase its density. Barite in drilling muds and sediments has a low solubility in seawater, because of the high natural concentration of sulfate in the ocean. Because it is insoluble in seawater, barite has a low bioavailability and toxicity to marine organisms.

Mud contamination - PetroWiki

A mud is said to be contaminated when a foreign material enters the mud system and causes undesirable changes in mud properties, such as density, viscosity, and filtration. Generally, water-based mud systems are the most susceptible to contamination. Mud contamination can result from overtreatment of the mud system with additives or from material entering the mud during drilling.
