  • Patent number: 11989394
    Abstract: Devices, methods and graphical user interfaces for manipulating user interfaces based on fingerprint sensor inputs are provided. While a display of an electronic device with a fingerprint sensor displays a first user interface, the device may detect movement of a fingerprint on the fingerprint sensor. In accordance with a determination that the movement of the fingerprint is in a first direction, the device allows navigating through the first user interface, and in accordance with a determination that the movement of the fingerprint is in a second direction different from the first direction, the device allows displaying a second user interface different from the first user interface on the display.

  • Patent number: 5431230
    Abstract: A crooked, slanted, cased wellbore extends downhole to a pay zone which is produced by a rod actuated downhole pump that lifts fluid from the bottom of the wellbore up through a tubing string to a wellhead. The pump is seated in a pump cavity, and the tubing string is tensioned at opposed ends while it is rotated. The upper end of the tubing string is attached to a fluid conveying swivel and a tubing rotator. A tubing anchor having a fluid conveying rotatable mandrel is attached adjacent to and forms part of the lower end of the tubing string by which the lower end of the tubing string is rotatably tensioned and releasably affixed to the casing in proximity to the lower end of the wellbore. A plurality of radially active slips are actuated in response to manipulation of the tubing string to extend the slips into engagement with the casing wall and to retract the slips in order to remove the tubing string from the borehole.

The pump is seated in a pump cavity, and the tubing string is tensioned and is rotated. The upper end of the tubing string is attached to a fluid conveying swivel and a tubing rotator. A combination tubing anchor having a fluid conveying rotatable mandrel is attached adjacent to and forms part of the lower end of the tubing string by which the lower end of the tubing string is rotatably and releasably affixed to the casing in proximity to the lower end of the wellbore. A plurality of radially active slips are actuated in response to manipulation of the tubing string to extend the slips into engagement with the casing wall and to retract the slips in order to remove the tubing string from the borehole.

  • Patent number: 5139090
    Abstract: A cased wellbore extends downhole to a pay zone which is produced by a rod actuated downhole pump that lifts fluid from the bottom of the wellbore up through a tubing string to a wellhead. The pump is seated in a pump cavity. The tubing string is tensioned and is rotated. The upper end of the tubing string is attached to a fluid conveying swivel means and a tubing rotator. A combination tubing anchor and fluid conveying swivel is attached adjacent the lower end of the tubing string by which the lower end of the tubing string is rotatably and releasably affixed to the casing in proximity to the lower end of the wellbore. The lower swivel is located adjacent the anchor and enables the tubing string to rotate respective to the anchor while conveying fluid through the rotating tensioned production tubing string.

  • Patent number: 4860826
    Abstract: Method and apparatus for hanging and sealing a tubing string in a high pressure wellbore. The invention discloses apparatus which enables the pulling of a tubing string on an injection well to be achieved without having to kill or bleed down the formation pressure. A support and flow control apparatus is provided for supporting the upper end of a tubing string that extends downhole in a cased borehole, while packing off the annulus between the tubing and the casing. The apparatus includes a tubing hanger which is connected to the upper end of the wellbore for supporting the upper end of the tubing string therefrom so that the string is in tension.
