    摘要： Illustrative embodiments of systems for characterizing resonance behavior of magnetostrictive resonators are disclosed. In one illustrative embodiment, an apparatus may comprise a first channel including one or more driving coils and one or more magnetostrictive resonators, the first channel having a first impedance; a second channel having a second impedance, the second impedance differing from the first impedance by an impedance attributable to the one or more magnetostrictive resonators; a signal source configured to apply an input signal to both the first and second channels; and a signal receiver configured to generate a combined output signal in response to output signals measured from both the first and second channels.

    摘要： An aqueous slurry composition for use in industries such as petroleum and pipeline industries that includes: a particulate, an aqueous carrier fluid, a chemical compound that renders the particulate surface hydrophobic, and a small amount of an oil. The slurry is produced by rendering the surface of the particulate hydrophobic during or before the making of the slurry. The addition of the oil greatly enhances the aggregation potential of the hydrophobically modified particulates once placed in the well bore.

    摘要： Flocculants and/or coagulants are used with recyclable drilling fluids to agglomerate particles and in particular fine solids (“fines”) including coal fines, such that they settle out of the fluid. The most widely used flocculants are different types of polymers including polyacrylamide (PMA) having different molecular weights, polyethylene oxide (PEO) having various molecular weights and other suitable polymeric flocculents known in coal beneficiation industry. For coal fines, other coagulants such as hydrocarbons, including kerosene, fuel oil, or a C5 to C8 hydrocarbon, either alone or in combination with a surfactant or a polymer, can also be used.

    摘要： The present invention provides hydrocarbon-based fracturing fluid compositions comprising a hydrocarbon fluid, proppant, and a small amount of water, and methods of using same. The small amount of water, preferably present at a concentration ranging from about 0.1% to about 5%, causes water bridging between the proppant particulates, causing the proppant particles to agglomerate. The compositions are useful in mitigating proppant flowback in hydraulic fracturing operations and are useful in isolating one or more zones in vertical as well as horizontal wells having multiple pay zones.

    摘要： A resin coated proppant slurry and a method for preparing a slurry is provided where the resin coated proppant particles are rendered less dense by attaching stable micro-bubbles to the surface of the resin coated proppants. A collector or frother may be added to enhance the number or stability of bubbles attached to the proppants. This method and composition finds use in many industries, especially in oil field applications.
