Baryte an overview ScienceDirect Topics
Barite (BaSO 4) is a widespread mineral in deep-sea sediments, varying between 1 and 10 wt% on a carbonate-free basis. It is the predominant barium phase in the ocean. BaSO 4 is known to compose a solid solution series with SrSO 4 as celestobarite in the skeletal portions of some marine organisms (i.e., the Xenophyophoria) and is often found inIntroduction. Carbon capture and storage (CCS) technologies have been studied worldwide to reduce and/or reuse anthropogenic carbon dioxide (CO 2) emissions [1].CCS technologies include pre-combustion, post-combustion, and oxy-fuel combustion processes, as well as methods to capture emitted CO 2.Captured CO 2 can be Barium carbonate precipitation as a method to fix and utilize

Application of Anhydrous Calcium Sulfate as a Weighting
The hydrostatic pressure exerted during the drilling operation is controlled by adding a weighting agent into drilling fluids. Various weighting materials such as barite, calcium carbonate, hematite, and ilmenite are used to increase the density of drilling fluids. Some weighting additives can cause serious drilling problems, including particle settling, Barium sulfate (barite) scale deposition may cause the problem in surface and subsurface production equipment resulting in reduced production, decrease in pressure, and premature failure of down holes equipment.
