Abstract:In the past few years, operators have been increasing the lateral lengths of horizontal wells to maximize the reservoir contact and production rates. However, the frictional forces between the coiled tubing (CT) and casing in those long lateral wells also increase, limiting the ability of conventional CT sizes to reach the end prior to lock-up occurring. Technologies such as lubricants, vibratory tools and tractors are usually used to extend the CT reach. However, the downhole performance of some of these fric… Show more
