This course will cover selected areas of drilling engineering such as horizontal and extended reach drilling. The course is structured by reviewing some fundamental areas such as trajectory design, torque and drag calculations and hydraulics. The candidates will develop an understanding of the fundamental principles and perform calculations to experience the behavior of the drilling system in practical terms. You will be able to design a trajectory, select an adequate drill string for the problem, considering drilling string tension and compression (buckling). You will also be able to determine system pressure losses, annular velocities to evaluate cuttings transport, as well as ECD in comparison with a pore pressure and fracture gradient.

This course will address advanced drilling topics which is essential and timely in today’s drilling technology climate. These topics were carefully selected to add to the skill set of a novice as well as advanced drilling engineer. The course intends to stress the appreciation of the complexity of the management of the drilling process to better integrate with company strategic goals. Key drilling efficiency improvements areas were presented in a way to emphasis real time drilling problems diagnostics, mitigations, prevention, and problem solving. Issues concerning technical limits, advanced wellbore stability analysis, pore pressure and fracture gradient estimation strategies. The course will typically provide theoretical background in the morning session and focus on exercises and problem solving in the afternoon session.

By the end of this course delegates will learn about:

• Important topics of drilling engineering
• Drill string mechanics: loads, cause of failure, design concepts
• Mechanized drilling operations: makeup of tubular, mechanized drilling rigs
• Drilling problems: stuck pipe situations, fishing operations
• Advanced drilling technologies - casing drilling, HPHT, coiled tubing drilling
• Proper selection of drilling technology for shale gas, geothermal drilling, etc.
• Non-conventional drilling methods and equipment including environmental aspects of drilling activities
• Drilling through gas hydrates
