ASSESSMENT OF THE FRICTION AND WEAR BEHAVIOR OF DRILLING TOOLS

Directional drilling has been used in the oil and gas industry for such a long
period. This technique usually cost the downhole drilling companies on such
damages upon the downhole tools. The damages are almost likely due to the
friction and wear behaviour resulted between the downhole tools and the wall of
the bore hole. In this thesis, an assessment on one of the factors will be done,
which is the drilling fluid. In this experiment, different kind of drilling fluid will
be used through the experiment, in order to get different wearing behavior. The
experiments will be done using the pin-on-disk test, with some minor
modifications, and fabrication on the rig or its components. The results will then
be tabulated into with respected to the type of drilling fluid
