Availability of CT as well known OCTG and the need to have new options on artificial lift prompted a CT consulting firm to investigate the use of CT to convey well fluids to the surface in oil and gas wells.The first idea consisted of a stationary CT attached to a modified rod pump to convey fluids to surface by the use of hydraulic pulses. This first approach triggers a second idea consisting in the reciprocation of CT as hollow sucker rod in rod pumping wells. Numerous tests for diverse applications are being performed with results to be covered in this paper.Because of the consequences of these innovations, another idea was tested, this time to reciprocate a subsurface pump capable of using the full cycle of the pumping unit with either conventional rods or CT. Latest field test results are part of this paper.
