Abstract: A method of simultaneously injecting a proppant and an acidic well treatment fluid into a subterranean formation is described. The method includes pumping the acidic fluid into the formation while simultaneously pumping a slurry of the proppant in a carrier fluid containing one or more friction reducing agents. The acidic fluid stream and the proppant slurry stream mix before entering the formation and are pumped at approximately equal rates. Also described is a system for simultaneously pumping the acidic fluid and the proppant slurry into the formation.

Abstract: A method of simultaneously injecting a proppant and an acidic well treatment fluid into a subterranean formation is described. The method includes pumping the acidic fluid into the formation at a high rate while simultaneously pumping a slurry containing a high concentration of proppant at a lower rate. Also described is a system for simultaneously pumping the acidic fluid and the proppant slurry into the formation.

Abstract: The invention describes improved environmentally friendly, non-toxic, CBM friendly, green fracturing compositions, methods of preparing fracturing compositions and methods of use. Importantly, the subject invention overcomes problems in the use of water-based mists as an effective fracturing composition particularly having regard to the ability of a mist to transport an effective volume of proppant into a formation. As a result, the subject technologies provide an effective economic solution to using high ratio gas fracturing compositions that can be produced in a continuous (i.e. non-batch) process without the attendant capital and operating costs of current pure gas fracturing equipment.
Abstract translation: 本发明描述了改进的环保，无毒，CBM友好的绿色压裂组合物，制备压裂组合物的方法和使用方法。 重要的是，本发明克服了使用水基雾作为有效的压裂组合物的问题，特别是考虑到雾将有效体积的支撑剂输送到地层中的能力。 因此，主题技术为使用高比率气体压裂组合物提供了有效的经济解决方案，该组合物可以在连续（即非批次）方法中生产，而无需当前纯气体压裂设备的资本和运营成本。
