The present invention relates to aqueous oilfield treatment fluids containing a gas component and fibers, wherein the fluids may further include a viscosifying agent and / or proppant. The fluids have good proppant suspension and transport properties as well as excellent gas phase stability. Use of fluids comprising an aqueous medium, a gas component, viscosifying agent, and fibers for hydraulically fracturing a subterranean formation, cleanup operations, and gravel packing a wellbore, are also disclosed.

Treatment methods including preparation of an aqueous treatment fluid composition composed of a carboxy modified polymer, a crosslinking agent, and a viscosifying quaternary amine salt, and subsequently introducing the composition into a the formation to treat. The treatment method is particularly useful for fracturing a subterranean formation. The polymer and crosslinker may be premixed and injected into a wellbore, then mixed therein with the quaternary amine salt to treat the formation. In another aspect, the polymer, crosslinker, and quaternary amine salt are mixed, injected into a wellbore, and introduced in the formation for treatment.

Methods for treating a formation penetrated by a wellbore which improves fluid loss control during treatment. In some aspects, the treatments include preparing an aqueous fluid including one or more water inert degradable polymers and an optional viscosifier, injecting the aqueous fluid into the wellbore at a pressure equal to or greater than the formation's fracture initiation pressure, and thereafter injecting into the wellbore a proppant laden fluid at a pressure equal to or greater than the formation's fracture initiation pressure. The water inert degradable polymer may be a polymer such as an emulsion polymer or a latex polymer. Some methods of the invention use a fluid which may have a normalized leak off coefficient (Cw / sqrt(K)) equal to or less than about 0.0022, 0.0014, or 0.0010. A conventional fluid loss additive may or may not be used in conjunction with the treatment fluid and / or the proppant laden fluid. The water inert degradable polymer may or may not substantially enter formation pores. In another aspect, methods for reducing matrix damage to a formation during a treatment operation include preparing an aqueous treatment fluid formed of at least one water inert degradable polymer, and injecting the fluid at a pressure equal or greater than the formation's fracture initiation pressure.

Method and apparatus for coating fertilizer in pellet or other form to impart time-release characteristics and the resulting coated pellet product. The polyurethane coating encapsulates fertilizer particles, forming a hydrophobic coating for slow-release qualities. The urethane polymer coating is formulated with an isocyanate and a combined fluid of a polyether polyol, a methyl ester derivative of plant or vegetable oil, a T-12 curing catalyst, barium sulfate, and an oil-based dye. The barium sulfate imparts physical strength to and enhances color quality of the polyurethane coating, and acts as a detackifier and maintains temperature in the coating reactor. The inventive formulation is effective in the practical polymer coating of sulfate-based or other fertilizer pellets in an inventive time-release fertilizer product. An apparatus is provided for carrying out the coating process.

Methods for inhibiting the depositions of organic contaminants from pulp in pulp and papermaking systems are disclosed. A combination of an enzyme and a nonionic polymeric detackifier are added to the pulp or applied to deposition-prone process equipment surfaces of a pulp and papermaking system.

Belonging to the field of chemical materials, the invention particularly relates to a water soluble rubber separant with antibacterial and mildewproof properties. The water soluble rubber separant provided by the invention comprises the following components by weight part: 1-8 of a stearic acid salt, 2-10 of a thickening agent, 1-6 of an anti-sticking agent, 1-6 of a surfactant, 2-8 of vegetable oil, 1-5 of soda ash, 1-5 of an emulsifier, and 2-6 of silicone oil. The water soluble rubber separant provided by the invention is safe, non-toxic, odourless, and harmless to the human body, has a good separation effect and small dosage, and is especially suitable for rubber products and sheet rubber. Being easy to dissolve in water, the water soluble rubber separant cannot generate precipitate due to different water quality. Tests show that, at a water temperature of 50DEG C, no precipitate is generated in 680 hours.
