Drilling and Well Design I

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

Introduction to drilling engineering. Fundamental concepts in oil well drilling. Well planning and cost estimation. Drilling team, drilling rigs, rig power system, hoisting system, circulation system, the rotary system, the well control system, well-monitoring system, special marine equipment, drilling cost analysis, and bit types available. Rock failure mechanisms. Bit selection and evaluation. Factors affecting tooth wear, bearings wear and terminating a bit run. Factors affecting penetration rate, bit operation, drilling fluids and drilling hydraulics, and well head equipment. Laboratory The laboratory section includes determination of rheological properties of drilling fluids.
