Abstract:
Coal friendly, non-toxic, green fracturing compositions, methods of preparing fracturing compositions and methods of use in various fracturing applications are described. The compositions are characterized as non-toxic compositions enabling effective use of the fracturing compositions in coal bed methane (CBM) formations and particularly shallow CBM formations. The compositions include a liquid component (water-based component) and a gas component in proportions that can support a proppant under turbulent conditions and that promote the formation of a mist.
