  • Patent number: 11486214
    Abstract: Apparatuses and methods for positioning a flexible hose into a wellbore with a protective housing are disclosed. A flexible hose is contained within a protective housing and both are positioned into a wellbore to a desired depth. Pressure can be applied to an interior of the protective housing, and a packoff seals between the flexible hose and the protective housing, causing the pressure to eject the hose from the protective housing.
    Type: Grant

  • Patent number: 11203901
    Abstract: Systems and methods for performing a radial drilling operation using a shaft are disclosed. The shaft can be flexible and can be made of a series of links, each of which can have a hexagonal or other suitable shape to impart a torque along the linkage. A cable system can be run through the middle of the links and can be resiliently tensioned to permit a different degree of flexure according to the amount of tension in the cable and resilient member. Accordingly, the shaft can be rigid, selectively permitted to flex, or can be brought back to a straight or at least a less-bent position.

  • Patent number: 11193332
    Abstract: Systems and methods presented herein include a drilling system that includes a deflecting device having an internal passage extending therethrough, and a flexible drilling assembly configured to extend through the internal passage of the deflecting device, and to create a perforation lateral tunnel in a wellbore. The flexible drilling assembly includes a flexible drive shaft configured to rotate relative to the internal passage of the deflecting device. The flexible drilling assembly also includes a cutting bit disposed at a first axial end of the flexible drilling assembly. The flexible drilling assembly further includes a slider tube disposed at a second axial end of the flexible drilling assembly. In addition, the flexible drilling assembly includes a slider radially disposed within the slider tube.
