Barite is a mineral composed of barium sulfate (BaSO 4 ). It receives its name from the Greek word "barys" which means "heavy." This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, medical, and ...

Barite scale is the most common oilfield scale in oil and gas wells. Barite scale removal still represents a challenge to the oil and gas industry because of its low solubility in mineral acids such as HCl. Chelating agents such as diethylene triamine pent acetic acid (DTPA), ethylene diamine tetra acetic acid (EDTA), and hydroxy ethyl ethylene tri acetic acid were introduced as barite scale ...

The new dissolver outperformed the common commercial dissolver used in the oil and gas industry. The new dissolver has a pH of 9 and showed safe use regarding the precipitation of dissolved solids that can be produced during the scale treatment and a low corrosion rate of 0.063 kg/m 2 at 6.9 MPa and 100 °C for 6 h. Also, the new dissolver was ...

Single phase microemulsions (SPMEs) and in situ-formed microemulsions may be used to clean up and remove non-polar materials from reservoir production zones of oil and gas wells. This clean up occurs by solubilization of the non-polar material into the microemulsion when the treatment fluid contacts the non-polar material. An in situ microemulsion may be formed when one or more surfactant and ...

Baryte, barite or barytes (UK: / ˈ b ær ʌ ɪ t /, / ˈ b ɛər aɪ t / [citation needed]) is a mineral consisting of barium sulfate (Ba S O 4). Baryte is generally white or colorless, and is the main source of the element barium.The baryte group consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid ...

(Chilingar, Mourhatch and Al-Qahtani 2008). Barite scales are typically grayish in color. Though pure barite is white, the scales may have impurities or organic materials trapped in them giving them a blackish tinge. Specific gravity of barite is around 4.5. The scales are fairly hard with Mohr hardness in the range 2.5-3.5.

Iron sulfide scale is a common problem in the oil and gas industry. The precipitation of the iron sulfide scale on the well completion tools or inside surface flow lines restricts the flow of the produced fluids and might affect the integrity of the pipelines or the surface and subsurface tools. Failure of the downhole completions tools will not only reduce the production rates but it might ...

Barite plugs. Barite, barium sulfate or BaSO4, is a finely ground inert weighting material often used to raise mud density. It is readily available on most drilling rigs. It can also be used for creating a solid, nearly impenetrable plug when it settles and packs off inside a wellbore.

Chelants (scale dissolvers) have a high thermodynamic driving force for dissolving sulfate scales such as barite, isolating and locking up the scale metallic ions within their closed cage-like structures (Fig. 2). These chemicals are successful at removing films of sulfate scale from the wellbore.
