ملخص

This study evaluates the performance of three lubricants on reducing friction between wellbore and coiled tubing (CT) and hence improving axial force transfer, reducing buckling, and enhances the limited reach of CT. The lubricants were evaluated using water-based drilling fluids composed of lubricants of different concentrations. Experiments were conducted in a lubricity tester and by using an in-house experimental setup that imitates the wellbore being drilled in the presence of drilling fluids. Results showed that reducing COF does not change CT buckling shape or mode, but it alters the initiation and transition between buckling modes and increases lock-up length. Effects of increasing lubricants percentages on mud properties were also examined. They showed positive impact compared to tests conducted without lubricants.
