Impact of barite and ilmenite mixture on enhancing the

Barite/ilmenite mixture has the potential to be used as alternative weighting material to barite in drilling mud technology. SEM micrographs of Na bentonite, barite and ilmenite particles were investigated to illustrate the morphological shapes of these particles and give an idea about the expected weighting mechanism via drilling operation.

Metals in Drilling Muds and Cuttings CONTROL DRILLING SOLIDS

May 31, 2018018332Nearly 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.

Barium concentration (i.e., from drilling mud barite) often exceeds 10000 g/g in sediments on the sea floor near offshore drilling discharges (Ray and Neff 2003). The metals in solid barite particles in the drilling mud plume in the water column and in the cuttings pile on the sea floor are not bioavailable.

Baryte

Baryte

Most baryte is ground to a small, uniform size before it is used as a filler or extender, an addition to industrial products, in the production of barium chemicals or a weighting agent in petroleum well drilling mud.

Mud contamination   PetroWiki

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.
