Fracturing fluids normally consist of many additives that serve two main purposes, firstly to enhance fracture creation and proppant carrying capability and secondly to minimize formation damage. Viscosifiers, such as polymers and crosslinking agents, temperature stabilizers, pH control agents, and fluid loss control materials are among the additives that assist fracture creation. Formation damage is minimized by incorporating breakers, biocides, and surfactants. More appropriate gelling agents are linear polysaccharides, such as Guar gum thickener, cellulose, and their derivatives.
Guar gum thickener are preferred as thickeners for enhanced oil recovery (EOR).
Guar gum thickener and its derivatives account for most of the gelled fracturing fluids.
Guar is more water-soluble than other gums, and Guar gum thickener is also a better emulsifier, because it has more galactose branch points.
Guar gum thickener shows high low-shear viscosity, but it is strongly shear-thinning.
Being non-ionic, Guar gum thickener is not affected by ionic strength or pH but will degrade at low pH at moderate temperature (pH 3 at 50 °C).
Guar's derivatives demonstrate stability in high temperature and pH environments.
Guar use allows for achieving exceptionally high viscosities, which improves the ability of the fracturing liquid to transport proppant.
Guar hydrates fairly rapidly in cold water to give highly viscous pseudoplastic solutions of, generally, greater low-shear viscosity than other hydrocolloids.
The colloidal solids present in guar make fluids more efficient by creating less filter cake.
Proppant pack conductivity is maintained by utilizing a fluid that has excellent fluid loss control, such as the colloidal solids present in Guar gum thickener.
Guar has up to eight times the thickening power of starch.
Derivatization of Guar gum thickener leads to subtle changes in properties, such as decreased hydrogen bonding, increased solubility in water-alcohol mixture, and improved electrolyte compatibility.
These changes in properties result in increased use in different fields, like textile printing, explosives, and oil-water fracturing applications.
Crosslinking Guar:
Guar molecules have a tendency to aggregate during the hydraulic fracturing process, mainly due to intermolecular hydrogen bonding.
These aggregates are detrimental to oil recovery because they clog the fractures, restricting the flow of oil.
Cross-linking guar polymer chains prevents aggregation by forming metal – hydroxyl complexes.
The first crosslinked guar gels were developed in the late ‘60s.
Several metal additives have been used for crosslinking, among them are chromium, aluminium, antimony, zirconium, and the more commonly used, boron.
Boron, in the form of B(OH)4, reacts with the hydroxyl groups on the polymer in a two step process to link two polymer strands together to form bis-diol complexes.
1:1 1,2 diol complex and a 1:1 1,3 diol complex, place the negatively charged borate ion onto the polymer chain as a pendant group.
Boric acid itself does not apparently complex to the polymer so that all bound boron is negatively charged.
The primary form of crosslinking may be due to ionic association between the anionic borate complex and adsorbed cations on the second polymer chain.
The development of cross-linked gels was a major advance in fracturing fluid technology.
Viscosity is enhanced by tying together the low molecular weight strands, effectively yielding higher molecular weight strands and a rigid structure.
Cross-linking agents are added to linear polysaccharide slurries to provide higher proppant transport performance, relative to linear gels.
Lower concentrations of guar gelling agents are needed when linear guar chains are cross-linked.
Guar gum thickener has been determined that reduced guar concentrations provide better and more complete breaks in a fracture.
The breakdown of cross-linked guar gel after the fracturing process restores formation permeability and allows increased production flow of petroleum products.

These decreases are thought to be a function of its high soluble fiber content.
Moreover, Guar gum thickener low digestibility lends its use in recipes as a filler, which can help to provide satiety or slow the digestion of a meal, thus lowering the glycemic index of that meal.
In the late 1980s, Guar gum thickener was used and heavily promoted in several weight-loss drugs.
The US Food and Drug Administration eventually recalled these due to reports of esophageal blockage from insufficient fluid intake, after one brand alone caused at least 10 users to be hospitalized, and a death.
For this reason, Guar gum thickener is no longer approved for use in over-the-counter weight loss drugs in the United States, although this restriction does not apply to supplements.

Benefits of Guar gum thickener:
Guar gum thickener is well known for its ability to thicken and stabilize food products, but Guar gum thickener may also provide some health benefits.
Studies indicate that Guar gum thickener could be beneficial for a few specific areas of health, including digestion, blood sugar and cholesterol levels, and weight maintenance.
Digestive health:
Because Guar gum thickener is high in fiber, it may support the health of your digestive system.
One study found that Guar gum thickener helped relieve constipation by speeding movement through the intestinal tract.
Partially hydrolyzed Guar gum thickener consumption was also associated with improvements in stool texture and bowel movement frequency.
Additionally, Guar gum thickener may act as a prebiotic by promoting the growth of good bacteria and reducing the growth of harmful bacteria in the gut.
Thanks to its potential ability to promote digestive health, Guar gum thickener may also help treat irritable bowel syndrome.
One 6-week study following 68 people with IBS found that partially hydrolyzed Guar gum thickener improved IBS symptoms.
Plus, in some individuals, Guar gum thickener reduced bloating while increasing stool frequency.
Blood sugar:
Studies show that Guar gum thickener may lower blood sugar.
This is because it’s a type of soluble fiber, which can slow the absorption of sugar and lead to a reduction in blood sugar levels.
In one study, people with diabetes were given Guar gum thickener 4 times per day for 6 weeks.
It found that Guar gum thickener led to a significant decrease in blood sugar and a 20% drop in LDL (bad) cholesterol.
Another study observed similar findings, showing that consuming Guar gum thickener significantly improved blood sugar control in 11 people with type 2 diabetes.
Blood cholesterol:
Soluble fibers such as Guar gum thickener have been shown to have cholesterol-lowering effects.
Fiber binds to bile acids in your body, causing them to be excreted and reducing the number of bile acids in circulation.
This forces the liver to use cholesterol to produce more bile acids, leading to a decrease in cholesterol levels.
One study had 19 people with obesity and diabetes take a daily supplement containing 15 grams of Guar gum thickener.
They found that it led to lower levels of total blood cholesterol, as well as lower LDL cholesterol, compared to a placebo.
An animal study found similar results, showing that rats fed Guar gum thickener had reduced blood cholesterol levels, in addition to increased levels of HDL (good) cholesterol.
Weight maintenance:
Some studies have found that Guar gum thickener could aid weight loss and appetite control.
In general, fiber moves through the body undigested and may help promote satiety while reducing appetite.
In fact, one study showed that eating an additional 14 grams of fiber per day may lead to a 10% decrease in calories consumed.
Guar gum thickener may be particularly effective at reducing appetite and calorie intake.
One review of three studies concluded that Guar gum thickener improved satiety and reduced the number of calories consumed from snacking throughout the day.
Another study looked at the effects of Guar gum thickener on weight loss in women.
They found that consuming 15 grams of Guar gum thickener per day helped women lose 5.5 pounds (2.5 kg) more than those who took a placebo.

Guar gum thickener is always wise to opt for a reputed Guar gum thickener powder exporter as this miraculous powder offers health benefits like reduction of weight and easy bowel movement.
The Guar gum thickener powder needs to be boiled in hot water and is beneficial for people who want a reduction of weight as it reduces the calories inside the human body.
Thickening:
One use of Guar gum thickener is a thickening agent in foods and medicines for humans and animals.
Because Guar gum thickener is gluten-free, Guar gum thickener is used as an additive to replace wheat flour in baked goods.
Guar gum thickener has been shown to reduce serum cholesterol and lower blood glucose levels.
Guar gum thickener is also economical because Guar gum thickener has almost eight times the water-thickening ability of other agents (e.g. cornstarch) and only a small quantity is needed for producing sufficient viscosity.
Because less is required, costs are reduced.
In addition to Guar gum thickener's effects on viscosity, its high ability to flow, or deform, gives it favorable rheological properties.
Guar gum thickener forms breakable gels when cross-linked with boron.
Guar gum thickener is used in various multi-phase formulations for hydraulic fracturing, in some as an emulsifier because it helps prevent oil droplets from coalescing, and in others as a stabilizer to help prevent solid particles from settling and/or separating.
Fracking entails the pumping of sand-laden fluids into an oil or natural gas reservoir at high pressure and flow rate.
This cracks the reservoir rock and then props the cracks open.
Water alone is too thin to be effective at carrying proppant sand, so Guar gum thickener is one of the ingredients added to thicken the slurry mixture and improve its ability to carry proppant.
There are several properties which are important:
1. Thixotropic: the fluid should be thixotropic, meaning it should gel within a few hours.
2. Gelling and de-gelling: The desired viscosity changes over the course of a few hours.
When the fracking slurry is mixed, it needs to be thin enough to make it easier to pump.
Then as Guar gum thickener flows down the pipe, the fluid needs to gel to support the proppant and flush it deep into the fractures.
After that process, the gel has to break down so that Guar gum thickener is possible to recover the fracking fluid but leave the proppant behind.
This requires a chemical process which produces then breaks the gel cross-linking at a predictable rate.
Guar+boron+proprietary chemicals can accomplish both of these goals at once.
Ice crystal growth:
Guar gum thickener retards ice crystal growth by slowing mass transfer across the solid/liquid interface.
Guar gum thickener shows good stability during freeze-thaw cycles.
Thus, Guar gum thickener is used in egg-free ice cream.

People use Guar gum thickener for constipation, diarrhea, irritable bowel syndrome (IBS), high cholesterol, and high blood pressure.
Guar gum thickener is also used for obesity, diabetes, and many other conditions, but there is no good scientific evidence to support these other uses.
Solubility and viscosity of Guar gum thickener:
Guar gum thickener is more soluble than locust bean gum due to its extra galactose branch points.
Unlike locust bean gum, Guar gum thickener is not self-gelling.
Either borax or calcium can cross-link Guar gum thickener, causing it to gel.
In water, Guar gum thickener is nonionic and hydrocolloidal.
Guar gum thickener is not affected by ionic strength or pH, but will degrade at extreme pH and temperature (e.g. pH 3 at 50 °C).
Guar gum thickener remains stable in solution over pH range 5–7.
Strong acids cause hydrolysis and loss of viscosity and alkalies in strong concentration also tend to reduce viscosity.
Guar gum thickener is insoluble in most hydrocarbon solvents.
The viscosity attained is dependent on time, temperature, concentration, pH, rate of agitation and particle size of the powdered gum used.
The lower the temperature, the lower the rate at which viscosity increases, and the lower the final viscosity.
Above 80°, the final viscosity is slightly reduced.
Finer guar powders swell more rapidly than larger particle size coarse powdered gum.
Guar gum thickener shows a clear low shear plateau on the flow curve and is strongly shear-thinning.
The rheology of Guar gum thickener is typical for a random coil polymer.
Guar gum thickener does not show the very high low shear plateau viscosities seen with more rigid polymer chains such as xanthan gum.
Guar gum thickener is very thixotropic above 1% concentration, but below 0.3%, the thixotropy is slight.
Guar gum thickener shows viscosity synergy with xanthan gum. Guar gum thickener and micellar casein mixtures can be slightly thixotropic if a biphase system forms.

This gum has the property of getting dispersed into the water while hydrating and swelling quickly to form a viscous solution.
The viscosity depends on factors like temperature, pH value, agitation rate, size of the particle, and concentration.
Lower Temperatures mean lower viscosity and such tips are offered by reputable manufacturers.
They also suggest that above the temperature of 80 degrees the final viscosity gets slightly reduced.
While choosing the quality Guar gum thickener is also essential to check for the finer gum powder as Guar gum thickener swells up more rapidly than the coarsely powdered gum.
Origin of Guar gum thickener:
Guar gum thickener is derived from the Cyamopsis tetragonoloba plant, a member of the Leguminosae family.
The domesticated species has been cultivated for centuries in India and Pakistan for human consumption and animal feed.
Guar gum thickener production in the United States was developed in the late 1940s and early 1950s.
Mainly, as a replacement to locust bean gum in the textile and paper manufacturing.
Chemical composition of Guar gum thickener:
Chemically, Guar gum thickener is an exo-polysaccharide composed of the sugars galactose and mannose.
The backbone is a linear chain of β 1,4-linked mannose residues to which galactose residues are 1,6-linked at every second mannose, forming short side-branches.
Guar gum thickener has the ability to withstand temperatures of 80 °C (176 °F) for five minutes.
Manufacturing process of Guar gum thickener:
Depending upon the requirement of end product, various processing techniques are used.
The commercial production of Guar gum thickener normally uses roasting, differential attrition, sieving, and polishing.
Food-grade Guar gum thickener is manufactured in stages.
Guar split selection is important in this process.
The split is screened to clean it and then soaked to pre-hydrate it in a double-cone mixer.
The prehydrating stage is very important because it determines the rate of hydration of the final product.
The soaked splits, which have reasonably high moisture content, are passed through a flaker.
The flaked guar split is ground and then dried.
The powder is screened through rotary screens to deliver the required particle size.
Oversize particles are either recycled to main ultra fine or reground in a separate regrind plant, according to the viscosity requirement.
The soaked splits are difficult to grind.
Direct grinding of those generates more heat in the grinder, which is not desired in the process, as it reduces the hydration of the product.
Through the heating, grinding, and polishing process, the husk is separated from the endosperm halves and the refined guar split is obtained.
Through the further grinding process, the refined guar split is then treated and converted into powder.
The split manufacturing process yields husk and germ called “guar meal”, widely sold in the international market as cattle feed.
It is high in protein and contains oil and albuminoids, about 50% in germ and about 25% in husks.
The quality of the food-grade Guar gum thickener powder is defined from its particle size, rate of hydration, and microbial content.
Manufacturers define different grades and qualities of Guar gum thickener by the particle size, the viscosity generated with a given concentration, and the rate at which that viscosity develops.
Coarse-mesh Guar gum thickener will typically, but not always, develop viscosity more slowly.
They may achieve a reasonably high viscosity, but will take longer to achieve.
On the other hand, they will disperse better than fine-mesh, all conditions being equal.
A finer mesh, such as a 200 mesh, requires more effort to dissolve.
Modified forms of Guar gum thickener are available commercially, including enzyme-modified, cationic and hydropropyl guar.
