发明名称 RESETTABLE BALL SEAT
摘要 <p>A device to allow a single ball size to actuate at least two downhole tools. Typically when a large number of ball actuated devices are run in a single well the total number of devices is limited by the increasing size of the balls required to actuate each sequential device. By having a mechanism that allows at least two tools to be actuated by each ball size the total number of ball actuated devices may be at least doubled. CD ) C0) CD co</p>
