Effect of Lubricants on the Lubricity of an Intervention Base Oil

During well intervention operations, the production tubing wall could be worn out due to mechanical interaction with coil tubing. Wear damage is a critical issue in the bend section where the contact force is higher. One of the possible solutions to reduce friction and wear damage is by increasing the lubricity of the intervention and the drilling fluid as well. The improved lubricity also minimizes the torque and drag that allows for reaching longer offset. This paper presents the experimental studies of the impact of six lubricants on industry intervention fluid. Results showed that the lubricants enhance the lubricity of the base oil. The optimized concentration of the lubricant reduced the coefficient of friction by 42-72 %.
