Extend Coiled Tubing Reach Using Polymers as Friction Reducers
Abstract
Coiled tubing is a cost- and time-effective technology for well intervention operations in oil and gas industry and it is used for different pumping and mechanical applications.
Nevertheless, because of buckling and lockup condition, coiled tubing can not reach the end of long lateral wells. Buckling phenomena happens by applying compressive force greater than critical buckling load on the end of coiled tubing.
Scientists have proposed different technologies such as lubricants, vibratory tools, tractors and taper designs to extend coiled tubing reach.
Among these technologies, lubricant is the simplest solution that can be used alone and in combined to other solutions for coiled tubing operations.
In this work, we will investigate the performance of several environmentally friendly lubricants as friction reducers and we will concentrate on new methods other than lubricant to extend coiled tubing reach.
In order to explore the efficiency of lubricant and our new solutions, we will design and build experimental set up to simulate behavior of coiled tubing inside lateral well.
