Sucker rod pumping commonly requires the tubing string assembly to be secured to the casing downhole near the pump to prevent tubing movement. Tubing movement can undesirably reduce downhole pump efficiency and result in premature failure of the tubing string, casing or sucker rods due to mechanical wear/fatigue. Downhole tubing anchors are used for this purpose, but they can bring about risks that can increase operating expense and limit production.
