  • Patent number: 11851987
    Abstract: An obstruction relief tool can include a plurality of walls that includes an inner wall, where the inner wall forms a cavity along a length of the inner wall. The obstruction relief tool can also include a chamber disposed between the plurality of walls, where the chamber has a proximal end and a distal end. The obstruction relief tool can further include an actuation device that is configured to actuate when an obstruction is within the cavity, where the actuation device, when actuated, is configured to open a first aperture in the inner wall that leads to the proximal end of the chamber, where the distal end of the chamber leads to a second aperture in the inner wall, where the first aperture is adjacent to the cavity above the obstruction, and where the second aperture in the inner wall is adjacent to the cavity below the obstruction.

  • Patent number: 11828152
    Abstract: The present disclosure provides methods and systems for hydrofracturing processes utilizing native drilling cuttings to enhance wellbore permeability. The native drilling cuttings are obtained during drilling operations and may be used in hydrofracturing applications without further grinding or processing. The native drilling cuttings can be combined into a slurry and injected into a well for the hydrofracturing application. In some cases, the native drilling cuttings are dried before combining them with the slurry.
