Guar gum an oil or natural gas reservoir at a 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 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 few hours. 2. Gelling and degelling: The desired viscosity changes over the course of a few hours. When the fracking slurry is mixed, it
Xanthan gum gum as a laxative. As described above, xanthan gum binds water very efficiently, which significantly aids passing stools. Some people react to much smaller amounts of xanthan gum with symptoms of intestinal bloating and diarrhea. There are many substitutes for xanthan gum when used for baking such as guar gum and locust bean gum. Xanthan gum is produced by the fermentation of glucose, sucrose, or lactose. The polysaccharide is prepared by the bacteria being inoculated into a sterile aqueous solution of carbohydrate(s), a source of nitrogen, dipotassium phosphate, and some trace elements. The medium is well-aerated and stirred, and the
