    摘要： An imaging agent, a method of production of the imaging agent, and the use of the imaging agent for microseismic monitoring of subterranean formations such as those generated during hydraulic fracturing. The acoustic emitting agent is tailorable for emission delay to ensure placement and frequency emission profiles for well region differentiation. This monitoring tool is highly useful in gas, oil, and geothermal well defining and stimulation monitoring.

    摘要： A composite particle that incorporates a material and is designed to undergo a reaction and/or mechanical or chemical change with the environment to increase in volume. The composite particle can be combined with a constraining matrix to create an expandable particle upon reaction. These particles can be used in stimulating wells, including oil and gas reservoirs.

    摘要： The present application is directed to a multifunctional coating for operation at temperatures in excess of 150° C., and up to 300+° C. The multifunctional coating includes: a) one or more polysilazanes (i.e., a group of silicon-based polymers) that include inorganic and/or organic functionalized polysilazane; b) one or more secondary polymeric additives one or more secondary polymeric additives (e.g., siloxane compounds and/or polysilane compounds); c) one or more optional functionalized nanoparticles and/or fillers; d) one or more optional additive polymers that include: i) Polysulfones (PSF) such as Polyethersulfone (PES) and/or Polyphenylene sulfide (PPS); ii) Polyimides (PI); iii) Polybenzimidazole (PBI); iv) Polybenzoxazoles (PBO); and/or v) fluoropolymers including Polytetrafluoroethylene (PTFE), Polyvinylidene fluoride or polyvinylidene difluoride (PVDF), Fluorinated ethylene propylene (FEP), and/or hexafluoropropylene (HFP); e) one or more optional additives (e.g., biocide, foaming agent, surface tension agent, pigment, curing agent, surface friction reducing agent, stabilizers, flexibilizers, inhibitors, flow control agents, anti-oxidants, degassing agents, dyes, coupling agent, dispersing agents, catalyst and/or hardeners; etc.); and f) one or more optional solvents; and which multifunctional coating is formulated such that it can optionally i) function as a high-temperature insulator, ii) have high elongation and/or improved hydrolytic stability, iii) have extreme weather resistance, iv) have high chemical resistance, v) have high impact and/or abrasion resistance, and/or vi) have improved thermal cycling resistance.
