A method of using a water based solution having a controllable gel time. The method includes providing a predetermined ratio of a water soluble silicate solution having at least one alkali metal, providing a predetermined ratio of a water dispersible polymer, and providing a predetermined ratio of a water soluble initiator containing a reactive carbonyl compound. One embodiment of the method also includes combining the water soluble silicate solution, the dispersible polymer, and the water soluble initiator and injecting downhole in a single stage treatment. Another embodiment of the method includes pre-mixing at least the water soluble silicate solution and the dispersible polymer into a mixture, then injecting the water soluble initiator and the mixture downhole separately for a multi-stage treatment with in situ mixing.

Multi-component aqueous gel solution for control of delayed gelation timing and for resulting gel properties

A water based solution having a controllable gel time is disclosed. The solution has predetermined ratios of a water soluble silicate solution having at least one alkali metal, a predetermined ratio of a water dispersible polymer, and a predetermined ratio of a water soluble initiator containing a reactive carbonyl compound.

A two-component, water based micro encapsulation composition and method for the cleanup of hydrocarbon spills or contaminates on various surfaces and media. The two-part formulation includes a first solution including water in a predetermined ratio of a water soluble alkaline silicate solution having at least one alkali metal and a predetermined ratio of at least one water soluble surfactant; and a second solution including water, a predetermined ratio of water soluble acid, a predetermined ratio of water dispersible polymer, a predetermined ratio of water soluble hydrotrope, and a predetermined ratio of at least one water soluble flocculating agent. A method of using the two-part formulation includes preparing the two-part formulation, allowing the first solution to contact the hydrocarbon or chemical contaminate; allowing the second solution to contact the first solution and contaminate to form a homogeneous mixture; and removing the homogeneous mixture.

Micro encapsulation composition for hydrocarbons and detoxification of highly hazardous chemicals and substances

The present invention relates to methods of recovering hydrocarbons or low polarity organic chemicals from hard surfaces, water and water surfaces, in their vapor state and from porous substrates. The hydrocarbons or low-polarity organic chemicals may be included in a spill. More particularly, the invention relates to the absorption of certain hydrocarbons and low-polarity organic chemicals by applying thermoplastic elastomers of a triblock copolymer of the general configuration A-B-A. The preferred A-B-A copolymer of the invention is a low to medium molecular weight hydrogenated polystyrene-poly(isoprene+butadiene)-polystyrene or polystyrene-b-ethylene/ethylene-propylene-b-styrene block copolymer. The method of forming a three-dimensional object from a hydrocarbon or low-polarity organic chemical absorbing substance includes: applying pressure to particles of a polymeric material comprising a styrene-ethylene/ethylene/propylene triblock copolymer containing from approximately 20 to 40 percent styrene, and; heating the particles for a period of time sufficient to form the three-dimensional object.

The hydrocarbons or low-polarity organic chemicals may be included in a spill. More particularly, the invention relates to the absorption of certain hydrocarbons and low-polarity organic chemicals by applying thermoplastic elastomers of a triblock copolymer of the general configuration A-B-A. The preferred A-B-A copolymer of the invention is a low to medium molecular weight hydrogenated polystyrene-poly(isoprene+butadiene)-polystyrene or polystyrene-b-ethylene/ethylene-propylene-b-styrene block copolymer. When the elastomeric block copolymer is applied to the hydrocarbon or low-polarity organic chemical, the elastomeric block copolymer absorbs the hydrocarbons or low-polarity organic chemicals to form a mat.

Method for absorption of hydrocarbons and low-polarity chemicals

A method for cleaning contaminated surfaces or for cleaning bulk contamination of hydrocarbons or chemicals. To clean hydrocarbon or chemical contaminated surfaces, a basic aqueous silica solution is sprayed onto the contaminated surface and allowed to dry. The resulting dry material will flake off, leaving a cleaned surface, without damaging the surface. To clean bulk contamination of hydrocarbons or chemicals, the basic silica solution is mixed with hydrocarbons or chemicals and then an acidic aqueous polymer solution is added and mixed. An amorphous silica material is immediately formed which permanently encapsulates the hydrocarbons or chemicals and which dries to an inert powder.

Micro encapsulation of hydrocarbons and chemicals

Blends of water soluble polymers containing varying ratios of acrylamide and sodium 2-acrylamido-2-methylpropane sulfonate are provided which synergistically increase the viscosity of acidic solutions. Improved methods of matrix acidizing and fracture acidizing are also provided.

Blends of water soluble polymers

Water soluble thickened acid compositions suitable for matrix or fracture acidizing are provided comprising water, an acid, and a water thickening amount of a copolymer of a N-vinyl lactam and an unsaturated amide. This composition can contain in addition a crosslinking agent to give a gelled acid composition. In a preferred embodiment, a lactam-containing copolymer is made in a diluent containing dissolved electrolytes. These compositions are particularly useful in acid or matrix fracturing in subterranean formations exhibiting a hostile environment, as exemplified by high temperatures and/or high concentration of multivalent metal cations.
