  • At-surface tool for pulse-injection of liquids
    Patent number: 8596300
    Abstract: For pulsed injection of liquids into the ground, the tool has a rotating cylinder, having through-slots. The tool has an insert, which is pressed against the rotating cylinder. As the cylinder rotates, the slots in the rotor cover/uncover the slots in the insert, creating the required pulses. By suitably shaping the slots, the pulses can have a fast rise-time from closed to open. The insert is shaped to minimize flow interference.
    Type: Grant

    Date of Patent: December 3, 2013
    Assignee: Wavefront Reservoir Technologies Ltd.
