Oil Drilling Grade Xanthan Gum

Oil Drilling Xanthan Gum Description


Xanthan gum is a polysaccharide derived from the bacterial membrane of Xanthomonas brassicae. It is used as a food additive and rheology modifier. It is usually used as a food thickener and stabilizer to prevent component separation. It is produced by the fermentation of glucose, sucrose or lactose by the Xanthomonas brassicae bacteria. After the fermentation period, the polysaccharide is precipitated from the growth medium with isopropanol, dried and ground into a fine powder. After that, it is added to the liquid medium to form a glue.

Performance characteristics

Xanthan gum is currently the internationally most superior bio-gum that integrates thickening, suspension, emulsification, and stability. The number of pyruvate groups in the molecular side chain ends of xanthan gum has a great influence on its performance. Xanthan gum has the general properties of long-chain polymers, but it contains more functional groups than general polymers, and will show unique properties under certain conditions. Its conformation in aqueous solution is diverse and exhibits different characteristics under different conditions.

1. Suspension and emulsification

Xanthan gum has a good suspending effect on insoluble solids and oil droplets. Xanthan gum sol molecules can form a super-bonded ribbon-like spiral copolymer, forming a fragile glue-like network structure, so it can support the shape of solid particles, droplets and bubbles, showing strong emulsification stabilization and high suspension ability.

2. Good water solubility

Xanthan gum can quickly dissolve in water and has good water solubility. Especially it can dissolve in cold water, which saves complicated processing and is convenient to use. However, due to its strong hydrophilicity, if water is directly added and the stirring is not sufficient, the outer layer will absorb water and expand into a micelle, which will prevent water from entering the inner layer, thereby affecting its function. Therefore, it must be used correctly. Xanthan gum powder or dry powder auxiliary materials such as salt and sugar are mixed well and then slowly added to the stirring water to make a solution for use.

3. Thickening

Xanthan gum solution has the characteristics of low concentration and high viscosity (the viscosity of 1% aqueous solution is equivalent to 100 times that of gelatin), and it is an efficient thickener.

4. Pseudoplasticity

The xanthan gum aqueous solution has high viscosity under static or low shear action, and under high shear action, the viscosity drops sharply, but the molecular structure remains unchanged. When the shearing force is eliminated, the original viscosity is immediately restored. The relationship between shear force and viscosity is completely plastic. The pseudoplasticity of xanthan gum is very prominent, which is extremely effective for stabilizing suspensions and emulsions.

5. Stability to heat

The viscosity of the xanthan gum solution will not change greatly with the change of temperature. The viscosity of general polysaccharides will change due to heating, but the viscosity of the xanthan gum solution will hardly change between 10-80℃, even at low concentrations. The aqueous solution still shows a stable high viscosity in a wide temperature range. 1% xanthan gum solution (containing 1% potassium chloride) is heated from 25°C to 120°C. Its viscosity is only reduced by 3%.

6. Stability to acid and alkali

Xanthan gum solution is very stable to acid and alkali, and its viscosity is not affected when the pH is 5-10. When the pH is less than 4 and greater than 11, the viscosity changes slightly. In the range of PH3-11, the difference between the maximum and minimum viscosity is less than 10%. Xanthan gum can be dissolved in a variety of acid solutions, such as 5% sulfuric acid, 5% nitric acid, 5% acetic acid, 10% hydrochloric acid and 25% phosphoric acid, and these xanthan gum acid solutions are quite stable at room temperature. The quality of the products will not change after several months. Xanthan gum is also soluble in sodium hydroxide solution and has thickening properties. The resulting solution is very stable at room temperature. Xanthan gum can be degraded by strong oxidants, such as perchloric acid and persulfuric acid, and the degradation accelerates as the temperature increases.

7. Stability to salt

Xanthan gum solution can be miscible with many salt solutions (potassium salt, sodium salt, calcium salt, magnesium salt, etc.), and the viscosity is not affected. Under the condition of higher salt concentration, its solubility is maintained even in saturated salt solution without precipitation and flocculation, and its viscosity is hardly affected.

8. Stability to enzymatic hydrolysis

The stable double helix structure of xanthan gum makes it have strong anti-oxidation and anti-enzymatic ability. Many enzymes such as protease, amylase, cellulase and hemicellulase cannot degrade xanthan gum.


Xanthan gum application


In the petroleum industry, due to its strong pseudoplasticity, a low-concentration xanthan gum (0.5%) aqueous solution can maintain the viscosity of the drilling fluid and control its rheological properties, so the viscosity is extremely small at the high-speed rotating drill bit. It saves power; while maintaining a high viscosity in the relatively static drilling site, preventing the well wall from collapsing. And because of its excellent salt resistance and heat resistance, it is widely used in drilling in special environments such as oceans and high-salt zones, and can be used as an oil displacement agent to reduce dead oil areas and increase oil recovery.
