Thru Tubing Solutions’ XRV is a dynamic excitation tool that enables coiled tubing to reach depths that were previously unobtainable. Engineered without moving parts or elastomers, our XRV can handle virtually any environment, chemical or temperature. The innovative, compact design utilizes a specialized flow path to create a varying flow resistance which acts much like an opening and closing valve. The XRV is the shortest, most reliable downhole extended reach tool on the market.
