Abstract:
1. A system for generating an energized fracturing fluid mixture for hydraulically fracturing a downhole formation, the system comprising: (a) a fracturing base fluid source; (b) a base fluid pump fluidly coupled to the fracturing base fluid source, and configurable to pressurize a liquid base fluid to at least a fracturing pressure of a formation; (c) a liquefied natural gas (“LNG”) source; (d) an LNG pump assembly fluidly coupled to the LNG source and comprising a pump component configurable to pressurize LNG to at least the fracturing pressure, and a heater component configurable to vaporize pressurized LNG to a gaseous phase; and (e) a fracturing fluid mixer having a first inlet fluidly coupled to the base fluid pump, a second inlet fluidly coupled to the LNG pump assembly and an outlet for coupling to a wellhead, and for mixing the liquid base fluid and gaseous natural gas to form a fracturing fluid mixture for injection into the wellhead.
