摘要： A method for fraccing oil or gas wells to recover natural gas. Liquefied natural gas is vaporized to form a foam or dense fluid. The foam or dense fluid is compressed to high pressures. The high pressure natural gas foam or dense fluid is fed into the oil or gas well and once the well is pressurized to a predetermined pressure and fracturing has begun, the flow of the foam or dense fluid is stopped. After a suitable period for fracturing to occur, the flow is reversed and the natural gas from the well and the foam or dense fluid fracturing fluid is recovered. The recovered and produced natural gas can be treated and made ready for use in other applications.

摘要： A method for concentrating a single gas component from a gas mixture is disclosed. The method utilizes concentration units and recovery units to concentrate the single gas component which is often at very low concentrations in the gas mixture. This method allows for the recovery of a valuable gas depending upon application such as oxygen and Ar-40.
摘要翻译：公开了一种从气体混合物中浓缩单一气体组分的方法。该方法利用浓缩单元和回收单元来浓缩气体混合物中通常浓度非常低的单一气体组分。该方法允许根据诸如氧气和Ar-40的应用来回收有价值的气体。

摘要： Methods for recovering argon from a natural gas stream being purified are disclosed. The argon will be separated from the natural gas with helium and other impurities and can be recovered as liquids from the flash separation step of purifying the helium. The argon that is separated from the helium can be rectified to remove further impurities from the argon which can be recovered for storage or other uses.

摘要： Stable, gas-fil!ed bubbles on the surface of proppant particles are formed by placing proppant in selected organic solvent having a much greater solubility of a selected gas compared to water, pressurizing the solvent with the selected gas, e.g., nitrogen, at pressures equal of greater than the operating pressure for a set time period to achieve saturation, and then replacing the solvent with water before reducing the pressure back to operating pressure level to create a local supersaturation near the solvent-solid interface, which will result in gas-filled bubble formation on the surface of proppant particles. The pressurized mixture of bubble surrounded proppant particles and water can then be combined with a respective fracturing fluid, e.g., slick water or carbon dioxide and/or nitrogen foam or an emulsion, which can be used in oil or gas producing wells to improve efficiency of hydraulic fracturing thereof.
摘要翻译：通过将支撑剂置于选定的有机溶剂中形成稳定的，气体填充气泡，所述选择性有机溶剂具有比水更高的选择气体的溶解度，与所选择的气体（例如氮气）在压力下加压溶剂等于设定时间段内的工作压力达到饱和，然后在将压力降低到工作压力水平之前用水替代溶剂，在溶剂 - 固体界面附近产生局部过饱和，这将导致气 - 支撑剂颗粒表面的填充气泡形成。支撑剂颗粒和水的加压泡沫混合物然后可以与相应的压裂流体（例如，光滑的水或二氧化碳和/或氮气泡沫或乳液）组合，其可以用于油或气体生产井中以提高效率水力压裂。
