A well treating composition containing a polysaccharide-based water-superabsorbent material has particularly applicability as a thermal insulating, fracturing or acid stimulation fluid. The water-superabsorbent material is capable of absorbing, at a minimum, its own weight. Particularly effective are biodegradable materials containing guar gum and carrageenan. The composition may further contain a crosslinking agent, brine and / or a viscosifying polymer or a gelling agent. As an oil-based fluid, the crosslinking agent is absorbed onto the water-superabsorbent material and serves to effectively delay crosslinking.

Disclosed are nutritional compositions having a solid crisp matrix, or a flour derived from the solid crisp matrix, said matrix comprising (A) from about 10% to about 50% by weight of a soluble viscous fiber, preferably guar; (B) from about 10% to about 99% by weight of a carbohydrate other than and in addition to the soluble viscous fiber; and (C) from about 1% to about 49% by weight of protein, wherein the matrix has a bulk density of less than about 0.4 g / cc. It has been found that soluble viscous fiber sources such as guar gum can be formulated into a solid crisp matrix, which then minimizes several limitations commonly associated with the formulation of such fiber sources into a conventional nutrition bar, e.g. slimy mouthfeel, tooth packing. These compositions are especially effective when formulated with gelled inclusions, including those containing or associated with acidulants, sour flavorants, or both. The nutritional compositions are especially useful as satiety agents, weight reduction agents, and / or for blunting the postprandial glycemic response in diabetics or other individuals in whom such a response would be beneficial.

In the presence of certain polyols, a guar gum or similar polysaccharide thickener solution is boron crosslinked before achievement of complete hydration of the thickener, without compromising the viscosity level achieved in a fracturing fluid by the time it is pumped into the wellbore and fractures the subterranean formation adjacent the wellbore. Methods continuously involve hydrating a polysaccharide thickener to an extent of 10% to 75%, but less than full hydration. Before 75% hydration is exceeded, a boron crosslinker is added. Upon addition of the boron crosslinker, the fluid is injected into the wellbore to stimulate hydrocarbon production. Because less time is needed for hydration, well site mixing equipment is down-sized smaller to achieve better efficiency and cost savings.
