Drilling Technology I

At the end of the course, students should be able to: 1. demonstrate understanding of the fundamentals of oil well drilling especially the techniques employed for oil well completion; 2. understand Bit selection and evaluation and bit’s ability to drill through reservoir rock by considering bit tooth wear on bit bearings and how to terminate the bit run; and 3. be able to plan a drilling operation to include cost estimation, assemblage of a Drilling team, rigs and rig power systems and hoisting.
