  • Patent number: 12624614
    Abstract: A downhole tool for cleaning a wellbore, the tool including a tool body having a flowpath therethrough. A liquid is configured to flow through the flowpath and may have an intermittent flow pattern. An inner sleeve positioned within the tool body includes a recess having a recess pattern. In response to the intermittent flow pattern, a shift pin positioned in the recess of the inner sleeve traverses through the recess pattern. The downhole tool includes at least one scraper blade. The scraper blade is movable between a retracted position and a radially expanded position. In response to the shift pin traversing the recess pattern of the recess, the scraper blade can be expanded radially outward toward a wall of the wellbore from the retracted position to the expanded position and/or retracted inward away from the wall of the wellbore from the expanded position to the retracted position.

  • Patent number: 12331634
    Abstract: Systems and methods are disclosed for controlling a downhole tool by encoding a tool control signal in a fluid flow and obtaining a temperature response downhole. In an example, a system for controlling a downhole tool includes a signal transmitter, a signal receiver, and a controller. The signal transmitter is uphole of the tool to be controlled (e.g., at surface) and encodes the tool control signal by varying one or more fluid flow parameters of a fluid flow down a well. The signal receiver is positionable in the well in fluid communication with the fluid flow. The signal receiver detects a temperature response in the fluid flow resulting from varying the one or more fluid flow parameters. A controller controls the downhole tool according to the temperature response.

  • Patent number: 12123890
    Abstract: A method for determining flow rates and phase fractions within a throughbore is disclosed. The method includes providing a mixture of one or more fluids through a fluid flow path in a throughbore at a flow rate, reducing the flow rate, slidably moving a first and second sleeve along the throughbore to a first position of a plurality of positions, measuring a first and second differential pressure at the first position, calculating a first loss pressure ratio from the first and second differential pressure. The method further includes slidably moving the first sleeve and second sleeve to each of the others of the plurality of positions in succession after the first position, measuring a plurality of differential pressures and calculating a loss pressure ratio at each of the plurality of positions, and calculating a plurality of flow rates phase fractions of the fluids flowing through the fluid flow path.
