    摘要: A system and method of applying periodic energy pulses to a portion of a wellbore, fracture(s), and/or near wellbore to interrogate and/or stimulate at least a portion of the wellbore, fracture(s), and/or near wellbore. The system includes a downhole device that is configured to deliver periodic energy pulses to a portion of the wellbore. The downhole device may deliver various energy pulses such as pressure waves, seismic waves, and/or acoustic waves. Sensors may determine properties of a portion of the wellbore and/or fracture based on energy pulses detected within the wellbore. The sensors may be connected to the downhole tool, may be positioned within the wellbore, and/or may be positioned at the surface. The magnitude and/or frequency of the periodic energy pulses may be varied to change the stimulation and/or interrogation of the wellbore.

    摘要: A method for fracturing a formation in a reservoir uses a fracturing fluid mixture comprising natural gas and a base fluid. The method comprises: determining certain reservoir conditions of the reservoir comprising the formation; selecting at least one desired behavior of the fracturing fluid mixture during a fracturing operation in the formation under the determined reservoir conditions; determining properties of the fracturing fluid mixture required to achieve the selected at least one behavior, preparing the fracturing fluid mixture having the determined properties; and injecting the fracturing fluid mixture into the reservoir under the determined reservoir conditions, such that the mixture exhibits the desired behavior during the fracturing operation. The determined properties include a mole fraction of natural gas in the mixture.

    摘要: A method of increasing hydrocarbon production, the method including fracturing downhole formation and disposing an expandable proppant into the downhole formation. The method further includes expanding the expandable proppant into contact with the downhole formation and holding open the downhole formation with the expandable proppant. A proppant having an expandable outer shell layer, wherein the expandable outer shell layer is configured to expand outwardly to a size at least 10 percent greater in an open position than in a closed position. A proppant delivery system having a tool body, an expandable injector disposed on the side of the tool body, and an expandable proppant disposed within the tool body.
