  • Patent number: 10479921
    Abstract: A method of forming a wellbore cement that includes a cross-linked polyamide. The polyamide is formed by reacting a di-functional amine with an aromatic tri-functional carboxylic acid. The wellbore cement composition is created by blending cement and water with the polyamide and then allowed to cure. Increases in compressive strength, Young's Modulus, and Poisson's Ratio of the cement were realized by adding the polyamide to the cement composition.

  • Patent number: 10274221
    Abstract: A heat exchanger for exchanging heat between air streams in two horizontally spaced ducts of a ventilation system. The heat exchanger includes a plurality of single-loop heat pipes, each with top and bottom legs extending along a heat pipe axis. A frame permanently mounts the heat pipes in the ventilation system so that sections of the legs are received in each duct and the legs are inclined with respect to a horizontal axis. The frame can define a non-rectangular interior. Heat pipe mounting features spaced apart along a width of the frame that can be offset along the height of the frame. A top or bottom of the frame can have an inclined inner side. In use, the frame is arranged in the ducts so that the inclined heat pipes provide whole-year heat recovery in cooling and heating modes.

  • Patent number: 9644133
    Abstract: Well-cementing compositions for use in high-pressure, high-temperature (HPHT) wells are often densified, and contain weighting agents such as hematite, ilmenite, barite and hausmannite. The weighting agents are usually finely divided to help keep them suspended in the cement slurry. At high temperatures, finely divided weighting agents based on metal oxides react with the calcium-silicate-hydrate binder in set Portland cement, leading to cement deterioration. Finely divided weighting agents based on metal sulfates are inert with respect to calcium silicate hydrate; consequently, set-cement stability is preserved.

The dispersing agents of the present invention comprise copolymers prepared by the radical copolymerization of at least one alkoxy-, aryloxy-, alkylaryloxy- or arylalkyloxy-polyalkylene glycol ethylenic urethane monomer with at least one anionic monomer and at least one non-ionic monomer, and optionally, an alkoxy-, aryloxy-, alkylaryloxy- or arylalkyloxy-polyalkylene glycol acrylate or methacrylate or an alkyloxy-, aryloxy-, alkylaryloxy- or arylalkyloxy-polyalkylene glycol allyl ether, and/or a crosslinking agent.

  • Patent number: 6713553
    Abstract: Cements or hydraulic binders may be prepared by adding an aqueous suspension comprising a ground mineral filler and at least one grinding aid agent to a cement or hydraulic binder. The resulting cement or hydraulic binder has very appreciably improved mechanical properties, particularly the property of “strength at young ages.” The grinding aid agent may be a natural or synthetic homopolymer and/or copolymer.

  • Patent number: 6706108
    Abstract: The present invention provides a novel method to produce grade road base material using recycled oilfield waste, called “oil and gas waste,” and aggregate waste and a novel road base material. Hydration and mixing of the waste materials along with a binder, will achieve an irreversible pozzolanic chemical reaction necessary for stabilization into a road base. An asphalt emulsifier may be included in the binder to manufacture asphalt stabilized road base. The entire method is a cold batch process.

  • Patent number: 6695545
    Abstract: A soil stabilization composition is provided for enhancing compaction and reducing permeability of different types of soil. The composition includes an acrylic copolymer resin, an enzyme and portland cement. The proportions of resin enzyme and cement will vary in accordance with the type of soil being treated. Sandier soils typically require higher volumes of product than sandier soils, and may require different relative compositions of ingredients.

  • Patent number: 6660799
    Abstract: The invention relates to the technical field of mortars, concretes, and other compositions based on cement, and in particular to agents capable of modifying their rheological characteristics, in particular workability. Workability may be defined as the property of a hydraulic binder to remain workable during as long a time as possible. The invention relates to novel agents of the acrylic copolymer type having urethane functions for improving the workability of hydraulic binders, to a method of preparing such novel agents, to binders containing them, and to uses for them. Such agents have the advantageous property of not retarding the setting time.
