Abstract:
A well cement composition includes a hydraulic well cement and multi-component fibers having at least a first polymeric composition and a second polymeric composition. At least a portion of the external surfaces of the multi-component fibers includes the first polymeric composition, and the first polymeric composition includes an ethylene-methacrylic acid or ethylene-acrylic acid copolymer. A method of cementing a subterranean well is also described. The method includes introducing the well cement composition into a wellbore, wherein the well cement composition further comprises water, and forming a cured cement in the wellbore.
Abstract:
An article comprising hollow ceramic microspheres and multi-component fibers is disclosed. The multi-component fibers are adhered together, and the hollow ceramic microspheres are adhered to external surfaces of the multi-component fibers. A method of making the article and use of the article for insulation are also disclosed.
Abstract:
Fibers comprising a first thermoplastic composition having a softening temperature up to 120°C and a curable resin. Also disclosed are compositions comprising a plurality of fibers, with some of the fibers comprising a first thermoplastic composition having a softening temperature up to 120°C and some of the fibers comprising a curable resin. The fibers have an aspect ratio of at least 2:1 and a maximum cross-sectional dimension up to 60 micrometers. Fluid compositions containing the fibers and methods of contacting a subterranean formation using the fibers are also disclosed.
Abstract:
Multi-component fibers comprising at least one polymer having a softening temperature up to 150°C, and another polymer having a melting point of at least 130°C. The fibers are non-fusing up to at least 110°C. The fibers are useful, for example, for flowback control in wellbores and reservoirs.

A composite comprising a polymer and a plurality of the silica coated glass bubbles dispersed therein. Articles comprising the composite. Methods for making the silica coated glass bubbles.
Abstract:
A plurality of glass bubbles having, in combination, a D50 size of no greater than 13 micrometers, an average true density of no greater than 0.42 grams per cubic centimeter, and a 90% crush strength of at least 55 megapascals are described. Methods of making such glass bubbles and compositions and articles such as sheet molding compounds and dielectric layers prepared from such glass bubbles are also described.
Abstract:
A method of treating a siliciclastic, hydrocarbon-bearing formation is disclosed. The method includes contacting the hydrocarbon-bearing formation with a composition comprising solvent and a fluorinated amine oxide. Siliciclastic, hydrocarbon-bearing formations treated according to the method are also disclosed.
Abstract:
Fluid compositions and methods of making and using same are described, one composition comprising a well treatment fluid and an additive combined with the well treatment fluid, wherein the additive is selected from solids, liquids and combinations thereof, the additive having a surface shape, at least one property of the surface shape enabling it to change under influence of a controllable parameter after the composition is deployed into a hydraulic fracture or gravel pack. In methods of the disclosure, the additive exists initially in a first state, and then is changed to a second state. The first state may increase proppant flowback efficiency, while the second state may increase hydraulic conductivity. In certain embodiments, the additive may change back to its first state.
Abstract:
A metal matrix composite is provided, including a metal, inorganic particles, and discontinuous fibers. The inorganic particles and the discontinuous fibers are dispersed in the metal. The metal includes aluminum, magnesium, or alloys thereof. The inorganic particles have an envelope density that is at least 30% less than a density of the metal. The metal matrix composite has a lower envelope density than the matrix metal while retaining a substantial amount of the mechanical properties of the metal.
