Disclosed herein are mineral-based composites that comprise gypsum, syngenite, brucite and a hydrated magnesium sulphate mineral, and which are adapted to degrade when buried. Also disclosed herein are mineral mixtures which can be used to produce the mineral-based composites, as well as products, such as plantable containers, formed from the mineral-based composites and which degrade when buried.

Remediation of a hydrocarbon producing well bore in a subterranean formation includes injecting fluid containing self-degrading particulates into the well bore in order to stop production of hydrocarbon from the well bore prior to commencement of remedial operations and to temporarily seal the well bore from fluid transmission between the well bore and the formation prior to commencement of the remedial operations, and commencing the remedial operations upon the well bore. Examples of the remedial operations include injecting weighted fluid into the well bore, inserting a down-hole tool into the well bore, casing treatment, annulus treatment, well bore wall treatment, cementing, and refracturing. For refracturing, the fluid containing the self-degrading particulates can be injected until a down-hole pressure exceeds a fracture breakdown pressure of new fractures that will be produced by a perforating tool lowered into the well bore.

Disclosed herein are feedstock materials which can be used for the manufacture of industrial products and consumer goods. The feedstock materials comprise particles of a comminuted paper product having fibrous portions on an outer surface thereof distributed throughout a diagenetically formed mineral aggregate comprising gypsum, syngenite and magnesium hydroxide and/or magnesium sulphate. The feedstock material, and products produced therefrom, is adapted to degrade when buried. Also disclosed herein are methods for producing the feedstock materials, and products produced from the feedstock materials.

A polymeric formulation for green building materials for replacement of end products commonly formed from a broad range of materials, such as concrete and mixes thereof, cement and mixes thereof, petrochemical based mixes and products thereof, rubber, plastic wood domestic and commercial shingles of all types including cedar wood and ceramic verities, flooring of all types including ceramic tiles, recreational vehicles for water use and sports such as boats, automobile components and bodies, electrical wire coatings, all types of pipes commonly used in the plumbing, gas and oil industries including the replacement of pipes traditionally formed from poly vinyl chloride formulations, bricks and all other forms of architectural structures to list but a few. A method by which a biopolymer can be generated using a process requiring no heat or any other form of energy using an ionized aqueous cure agent is sprayed over a molded gel.

A concrete additive, which provides superior pump component protection, reduction of corrosion including wear and damage on pump components, and increased lifespan of the components in a concrete pump system. As concrete slurry mixes in the pump barrel of a ready mix cement truck, the concrete slurry blends directly with the pump additive and converges with the concrete pump components as the concrete blend mixes. This direct contact allows the pump additive to lubricate the component parts, which provides a corrosion inhibitor that protects the component parts from the harsh side effects of the aggregate rubbing against the liners, pistons and pump component parts thereby significantly extending the life of the component parts of the concrete pumping system. The cement additive compositions and methods of the present invention may be used in well bore drilling, cement production and delivery systems, and fracking operations.
