  • Adaptation of fracturing fluids
    Patent number: 10294768
    Abstract: Fracturing systems and methods for increasing the conductivity of a flow path between a reservoir formation and a wellbore are presented that include varying a proppant concentration of a fracturing fluid in response to a measured characteristic from the wellbore during the fracturing process. During the injection of proppant pulses into the wellbore, one or more of a pulse length, pulse height, pulse shape, or duty cycle of the proppant concentration is varied. Other systems and methods are disclosed.
    Type: Grant
    Filed: November 14, 2013
    Date of Patent: May 21, 2019
    Assignee: Halliburton Energy Services, Inc.
