Xanthan gum is a popular thickener and stabilizer used in a variety of industries, including the drilling mud industry. In drilling muds, xanthan gum helps to control the viscosity and rheology of the mud, improving its ability to suspend and transport drill cuttings. It also helps to minimize fluid loss and maintain the integrity of the wellbore.
Organic xanthan gum powder is a naturally occurring substance that is commonly used as a food thickener and stabilizer. Unlike conventional xanthan gum, which is often derived from genetically modified corn, organic xanthan gum is made from non-GMO corn starch and is certified organic, meaning that it is free from harmful chemicals and additives. Not only is organic xanthan gum healthier, it is also more environmentally sustainable, as it is produced using ethical farming practices that support biodiversity and protect the soil and water quality. Whether you're a home cook or a food manufacturer, choosing organic xanthan gum is a smart choice for both your health and the planet.
Petroleum Drilling Grade Xanthan Gum
Petroleum Drilling Grade Xanthan Gum is a type of polymer that is widely used in the oil and gas industry. It is produced through the fermentation of sugars by a bacteria called Xanthomonas campestris, and can be used as a thickening agent, stabilizer, and lubricant in drilling fluids.
What is Oil Industry Xanthan Gum
Xanthan gum is a polysaccharide that is used in the oil industry as a thickening agent and viscosifier. Xanthan gum is a byproduct of the bacterium, produced by fermenting renewable carbohydrates like starch, sucrose, or glucose syrup. In the oil industry, xanthan gum is used in large quantities to thicken drilling mud. When mixed with water, xanthan gum swells and becomes gel-like, which makes it a good carrier for drill cuttings. Xanthan gum's rheological properties provide improved low-end rheology. When circulation stops, the solids remain suspended in the drilling fluid.
Features of Oil Industry Xanthan Gum
Low-concentration xanthan gum solution has the characteristics of high viscosity (the viscosity of 1% aqueous solution is equivalent to 100 times that of gelatin), which can show efficient thickening effect in the field of oil exploration.
Xanthan gum solutions have high viscosity at static or low shear. Under high shear, the viscosity decreases but the molecular structure remains unchanged. When the shear disappears, the viscosity returns to normal.
The performance of xanthan gum suspension remains basically unchanged within a wide temperature range (-18--120°C), and the solution viscosity remains basically unchanged within the pH range of 1-12. Under conditions of higher salt concentration , no precipitation or flocculation.
It has good compatibility with acids, bases, salts, preservatives, natural or synthetic thickeners in the same solution system. It can have a synergistic effect with polysaccharide gums such as guar gum and locust bean gum to double the viscosity.
Application of Oil Industry Xanthan Gum
For Oil Drilling:
Drill Cuttings
It's a member of a family of polymers called hydrocolloids, which are both water-soluble and hydrophilic, meaning its molecules are attracted to water. Having an attraction to water is an essential characteristic of xantham gum, as water is the base carrier fluid in drilling muds. Operators use xanthan gum as a thickening agent in drilling muds to increase the mud's viscosity. When mixed into water, xanthan gum swells, and the mixture takes on a gel-like consistency that has proven to be an excellent carrier of drill cuttings. Even when the flow of drilling mud stops, the viscous mixture helps keep cuttings trapped in suspension instead of allowing them to fall down the drilling pipe due to gravity.
Oilfield
It may seem counterintuitive to pump hydrocarbons, like petroleum distillates, back into the ground, but there's an excellent reason they're used in conjunction with xanthan gum in drilling mud. Xanthan gum is water-soluble, but it's not oil-soluble. That means when it's mixed with a petroleum distillate, xanthan gum doesn't dissolve – it disperses. Trucks transport the pre-mixed dispersion to the well site in drums, totes, and pails, and massive pumps pump it to the wellhead, where it mixes with water and other additives before being sent down the wellbore.
Increase Oil Recovery
Among the various methods for enhancing oil recovery, polymer flooding occupies an important position. The role of the polymer is to adjust the rheology of water injection, increase the viscosity of the driving fluid, and improve the sweep efficiency of water flooding. Reduce the permeability of the formation water phase so that the water and oil can flow forward at a uniform speed. The physical simulation experiment further shows that the xanthan gum drilling fluid improves oil recovery, and it is a kind of oil field exploitation displacement agent with excellent performance. After completing primary and secondary oil extraction using conventional methods, more than 50% of the oil remains in the rock formations that cannot be recovered.
Others:
Paint Thickeners
The water-based dispersion paints popularly called acrylic paints or stable emulsion paints mainly include the application of Xanthan gum as a binder ( a film-forming element), pigments (to provide color to the paint), water, and various additives. Additives are the core constituents in the paint formulation process. When you mill the pigment with water and the required additives to gain accurate granule size for colloidal dispersion, it forms pigment paste. To give the ideal covering power, the colloidal dispersion should result in ca. 5 to 1000 nm granule size when you consider inorganic pigments. To adjust the viscosity of pigment paste, you add thickeners.
Paint Stabilizers
Xanthan gum is a well-known stabilizer that is soluble in cold and hot water. It remains stable with various pH ranges and is usually inert to the other chemicals. When you add Xanthan gum to water, it alters the rheological properties of pseudo plastic from Newtonian, thereby forming high viscosity when at rest and under low shear rates. This affects the stabilization of paints when you store them, to give the best adherence to the walls. While you apply the paint with a brush, spray, or a roller, Xanthan gum thus gives a shear rate thinning experience.
Latex Paints
Xanthan gum improves the product fluidity in water-based paints and latex paints. It can suspend the pigments and smoother the painting surface even while you paint on a vertical plane. Xanthan gum can control paint and coatings, keep up the diffusion and avoid sinking. You can control the excessive spraying through fog reduction to prevent the glaze from losing shape or sinking. It can also maintain great control over different colors to cater to vibrant glazes.
Xanthan gum is produced by the fermentation of glucose and sucrose. The medium is well-aerated and stirred, and the xanthan polymer is produced extracellularly into the medium. After one to four days, the polymer is precipitated from the medium by the addition of isopropyl alcohol, and the precipitate is dried and milled to give a powder that is readily soluble in water or brine.
It is composed of pentasaccharide repeat units, comprising glucose, mannose, and glucuronic acid in the molar ratio 2:2:1.
Synthesis originates from glucose as substrate for synthesis of the sugar nucleotides precursors UDP-glucose, UDP-glucuronate, and GDP-mannose that are required for building the pentasaccharide repeat unit. This links the synthesis of xanthan to carbohydrate metabolism. The repeat units are built up at undecaprenylphosphate lipid carriers that are anchored in the cytoplasmic membrane. Products of the gum gene cluster drive synthesis, polymerization, and export of the repeat unit.
Difference Between Guar and Xanthan Gum
These days, using gum as a stabilizing, suspending, and thickening agent in fluids has become extremely popular. Essentially, gums are natural polymers derived from various bacteria through fermentation using sugar and essential nutrients. Guar gum and Xanthan gum are the two main ingredients used as thickeners and emulsifiers in lubricants and textiles, concrete admixes, and oil well drilling fluids, among other things. But what is the difference between these gums? Read on to learn more.
Guar gum
It is a gel-forming fiber that's obtained from guar beans. It is a type of long-bonded carbohydrate molecule that has stabilizing and thickening properties beneficial in feed, food products, and industrial applications. The gum is typically composed of the complex carbohydrate polymer of mannose and galactose sugars in varying proportions. Guar gum is widely used in powder form as an additive in food manufacturing, oil well drilling, explosives, concrete admixes, textiles, and pharmaceuticals. Guar gum is also used in industrial applications due to its ability to create hydrogen bonding with water molecules. It has also been claimed that this gum has properties that might be beneficial in some fishing operations, printing pastes, and warp sizing.
Xanthan Gum
It is a series of sugar building blocks produced by fermenting a carbohydrate with Xanthomonas campestris bacteria. This gum has many industrial applications, including as a food additive, an excellent stabilizer, an emulsifier, and a thickening agent that bonds ingredients and stops them from separating. It's also largely utilized as a fluid loss additive in drilling mud as well as a set retarder in cementitious applications. Xanthan gum has many uses in the cosmetics industry and is a popular ingredient in processed foods. It helps create a fluffy texture for baked products, and those who avoid gluten use xanthan gum to achieve the gluten effect. Sometimes, Xanthan gum is used in adhesives, paints, shampoos, toothpaste, and creams.
Both guar and xanthan gums are natural polymers made from specific bacteria through a fermentation process using sugar and nutrients. They are effective thickening, suspending, and stabilizing agents used in fluids. The type of gum you choose will depend on your application needs.
- Drillers needing extra suspension have long reached for suspension enhancers to increase gel strength and keep the returns flowing. Every bentonite company has a slick brand name for them but, for the most part, they are xanthan gum-based products. Xanthan gum is a polysaccharide secreted by the bacterium Xanthomonas campestris. PAC, guar, diutan gum, and welan gum are other common polysaccharides. Diutan and welan are non-ionic, like guar gum, whereas xanthan gum has an anionic charge.
- For our drilling purposes, xanthan is an easy mixing biopolymer used to control drilling fluid rheology. It is designed to enhance gel strength for improved suspension and aid in transporting normal cuttings as well as heavier gravel and cobble. Our goal is to always keep the hole open and transport the cuttings outward.
Xanthan gum is a byproduct of the bacterium that rots vegetables like cauliflower and cabbage; it turns them black. In drilling, several factors make xanthan gum a great tool for the jobsite:
Suspension (gel strength).
Filter-loss improvements due to the anionic charge on the molecule, which helps improve filtrate loss; whereas, non-ionic gums like guar will flocculate bentonite.
Easy dispersal in drilling fluids.
- Its ability to work in saltwater adds to its versatility. This is due to its short, three-sugar-long sided chains that prevent the polymer from coiling up in salty conditions. This is unique for anionic polymers, and really makes xanthan stand out from other polysaccharide types.
- Most manufacturers sell their xanthan product in a powder. It can have a long shelf life if kept in a closed bucket and dry. In the field, we recommend you add it slowly through a hopper at maximum shear to avoid lumping and to minimize waste. Read your brand's instructions, but a normal dose is one-half to 1 pound per 100 gallons of drilling fluid.
