CO2 FRACTURING SYSTEM AND METHOD OF USE

摘要

An apparatus and method for delivering a thickened fluid mixture, including a C02 recapture system. The apparatus including a proppant storage vessel (102) and a fracturing fluid storage vessel (126) providing a continous supply of a proppant material (106) and a fracturing fluid to a mixing apparatus (124). The mixing apparatus (124) configured to output and deliver a thickened fluid mixture of the proppant, the fracturing fluid and a thickener agent at or above the fracturing fluid blending pressure to a high pressure pump assembly (142). The high pressure pump assembly (142) configured to deliver a high pressure thickened fluid mixture to one or more downstream components at an injection pressure. The apparatus including a C02 recapture system configured to recapture an exhaust stream from the one or more downstream components and/or other C02 output sources, and provide a purified and liquefied C02 fluid stream to the fracturing fluid storage vessel (126). The apparatus configured for continual operation.
