Abstract : Drilling an extended reach well acquires precise engineering in drilling the deviated and horizontal section of the
well as there are a lot of technical problems that can appear in these sections. The biggest issues that appear in the deviated
and horizontal sections of the well are high values of friction factor that leads to high values of torque and drag, material
wear of the joints, and inadequate cleaning of the well from cuttings. High values of torque moment and drag force represent
a big problem when drilling directional wells, and in general affect the possibility of reaching the designed path of the well.
One of the solutions to reduce torque and drag is to applicate lubricants in the drilling fluid to reduce the friction that appears
when drill string is in contact with casing or borehole. Normally one method doesn't always solve the issue alone, so in
conjunction with adding lubricants to water-based mud system, another solution is to add a protective ring on the tool
joints/pipe body of the drill string that would be made from materials that could reduce friction and wear. Protective rings
would be made from materials that have been used in the industry to produce various mechanical elements. In this paper
lubricants will be tested in different concentrations to conclude the optimal concentration to be used in water-based drilling
fluid and which material for the protective rings to be used for eventual practical use.
