  • Publication number: 20240240537
    Abstract: The present disclosed technology relates to a downhole tool activation device, and a method of using the device, where the valve is configured to open when the counter device has moved an activation distance in an activation direction, a piston engaged with the counter device, having a wellbore pressure from a fluid source applied to a first side, and a pressure in a fluid reservoir applied to the second side, the piston configured to move a step distance in a first direction when the wellbore pressure exceeds the pressure in the fluid reservoir, and configured to move a step distance in an opposite direction driven solely by a greater pressure in the fluid reservoir than the wellbore pressure, and a flow restrictor in fluid communication with the fluid reservoir and fluid source, configured to restrict the flow of fluid between the fluid source to the fluid reservoir.

  • Patent number: 11761289
    Abstract: A shearable sleeve supports a disintegrable plug element in a pipe string, and may include a first portion including a first circumferential end surface, a seat for supporting the disintegrable plug element, a second portion including a second circumferential end surface, and a surface extending axially between the first and second circumferential end surfaces and formed with one or more radial protrusions adapted to shear off from the rest of the sleeve when being exposed to a predefined axial force, and one or more recesses for receiving one or more loading devices for initiating disintegration of the disintegrable plug element upon contact with the plug, wherein one or more radial protrusions is/are axially offset relative to the first circumferential end surface. A plug device, as well as a plug assembly in a pipe string, may include the shearable sleeve.

  • Publication number: 20220235623
    Abstract: A plug assembly for opening a subterranean wellbore comprises a tubular housing and a first frangible element comprising an activation component. The first frangible element has a first orifice in an uphole side that extends at least partially through the first frangible element. The activation component initially seals the first orifice to prevent fluid communication from the uphole side of the first frangible element with the first orifice. After the activation component is activated, fluid communication is enabled from the uphole side of the first frangible element with the first orifice.
