This course will expose the candidates to terminology, concepts, processes, and equipment used to drill oil and gas wells. The planning process followed by drilling engineers is covered to the extent that participants will understand the process and be able to initiate a well plan and well design. Non-complex calculations and basic problems are included so that candidates will do and see how this is done by the drilling engineer. This course introduces the entry level drilling engineer to the drilling engineering profession. The candidates will be able to identify rig components, make simple rig sizing calculations, and describe basic drilling fluids, drillbit selection concepts, directional drilling plans and tools used in this technology. Additionally some cost estimating processes, fundamentals of well control, drilling tool selection and the important standards used in the drilling industry.
