  • Multi-stage downhole hydraulic stimulation assembly
    Patent number: 9920600
    Abstract: An assembly for performing multiple downhole hydraulic stimulation applications in a well. The different applications may be performed without removal of the assembly from the well between the different applications. So, for example, even a hydraulic perforating application may be performed with prior or subsequent clean-out applications. Yet, there is no need to remove the assembly for manual surface adjustment of the hydraulic perforating tool in order to allow for such clean-outs.
    Type: Grant

So, for example, even a hydraulic perforating application may be performed with prior or subsequent clean-out applications. Yet, there is no need to remove the assembly for manual surface adjustment of the hydraulic perforating tool in order to allow for such clean-outs. Thus, the time to run such multi-stage stimulation operations may be dramatically reduced.
