Course Objective

The course discusses the fundamentals of drilling, types of rigs used, procedures and the people who make the drilling equipment work. It also provides an overview of the key issues involved in selecting drilling targets, well planning, evaluation and completion, while ensuring drilling safety and efficiency. Typical challenges in drilling operations are also examined, offering solutions to overcome the hazards and risks that can exist. Advanced drilling concepts, principles and the latest technologies are also covered, further exploring industry dynamics which drive today's drilling and well operating activities.
