An Efficient Single Step Approach for Barium Sulfate (BaSO4)
The barite scale (barium sulfate) is considered one of the most common scales in oil and gas wells. Barite scale removal is crucial for flow assurance but it still represents a challenge to the oil and gas industry because of its low solubility in water and mineral acids such as HCl. Despite the huge amounts of chelating agents required to Sparingly soluble sulfate minerals, particularly barite (BaSO4), present an ideal system to understand mineral-water interfacial reactions.

What is Barite? • Earth
Barite (BaSO4) is a mineral consisting of barium sulfate. It is generally white or colorless, and is the main source of barium. Baryte is the British spelling. The radiating form is also sometimes refered to as Bologna Stone. Barite commonly occurs in lead-zinc veins in limestones, in hot spring deposits, and with hematite ore.@article{osti_1859212, title = {Studies of Mineral Nucleation and Growth Across Multiple Scales: Review of the Current State of Research Using the Example of Barite (BaSO 4 )}, author = {Weber, Juliane and Bracco, Jacquelyn N. and Yuan, Ke and Starchenko, Vitalii and Stack, Andrew G.}, abstractNote = {Sparingly soluble sulfate Studies of Mineral Nucleation and Growth Across Multiple

Minerals Free Full-Text The Formation of Barite and Celestite
Barite (BaSO4) and celestite (SrSO4) are the end-members of a nearly ideal solid solution. Most of the exploitable deposits of celestite occur associated with evaporitic sediments which consist of gypsum (CaSO42H2O) or anhydrite (CaSO4). Barite, despite having a broader geological distribution is rarely present in these deposits. In this Properties in Thin Section Anhydrite is colorless in thin section, displays up to third-order green interference colors, has pseudocubic cleavage, and displays parallel extinction.Gypsum has lower relief and birefringence; barite and celestite have higher indices of refraction and low birefringence.

Controls on Barite (BaSO4) Precipitation in Unconventional
Barite (BaSO4) precipitation is one of the most ubiquitous examples of secondary sulfate mineral scaling in shale oil and gas reservoirs. Often, a suite of chemical additives is used during fracturing operations to inhibit the accumulation of mineral scales, though their efficacy is widely varied and poorly understood. This study combines Experimental studies on the phase transition and thermoelastic behavior of barite-group minerals are crucial to understand the recycle of sulfur in Earth’s interior.
