Abstract: Systems, compositions, apparatus, and methods for hydraulically fracturing a subterranean formation traversed by a wellbore including mixing a gelling agent and water to form a base fluid, adding a gas and a proppant to the base fluid to form a foam fluid, alternating injecting into the formation the base fluid and the foam fluid, repeating the alternating injecting, forming regions of higher proppant concentration, and forming channels adjacent to the regions. Systems, compositions, apparatus, and methods for hydraulically fracturing a subterranean formation traversed by a wellbore including forming a base fluid with a gelling agent, forming a foam fluid with a gas and a proppant, injecting into the formation the base fluid, injecting into the formation the foam fluid, repeating the injecting the base fluid and foam fluid, and forming channels in the base fluid with faster flow than flow in the foam fluid.

Abstract: A system for capturing a target species from an exhaust gas stream generated by at least one engine at a surface of a wellbore utilized in reservoir stimulation for subsurface energy recovery. The system includes a heat exchanging system for cooling the exhaust gas stream to a predetermined temperature. The system includes a water separation unit for separating a liquid from the cooled exhaust gas stream. The system includes a target species capture module for capturing the target species from the cooled exhaust gas stream. The system includes a target species regeneration module to extract the captured target species. The system includes a target species compression module for liquefying the captured target species. The system includes a target species storage module for storing the liquified target species, wherein the system is mounted on a mobile platform for transportation to and from the surface of the wellbore.
