Basic Drilling, Completion and Workover Operations

YOU WILL LEARN

• How drilling, completing and reworking a well affects its ability to produce
• What can be done within open-hole and cased wells, as a part of reservoir management
• How drilling practices can damage or stimulate producing wells

ABOUT THE COURSE

This course gives a technical overview of the science and art of drilling operations, completion practices and post-completion wellbore enhancement or remedial workover techniques (well intervention). It develops an understanding of the WHAT, WHY, and HOW of each of these areas of engineering practice. Reservoir Engineers will learn what can be done within open-hole and cased wells as they execute reservoir management. Drilling and completion personnel will learn how the producing reservoir can be damaged or stimulated by what they do. The participants learn to visualize what is happening "downhole", discover what can be accomplished and gain an appreciation for wellbore risks and the possibility of damage to the formation; and how drilling and completion practices can alter reservoir interpretation and performance. The participant will become conversant with specific technical terminology and aware of practical applications, which should enhance communication and interaction between disciplines.

Overview of workover techniques:

• Stimulation application: surfactants, solvents, acidizing, fracturing & deep perforating 
• Formation & sand control: screens, chemical consolidation, gravel packing, frac-pack, new & novel techniques
• Scale & corrosion

PARTICIPANT

Technical, field, service, support and supervisory personnel desiring to gain an introductory overview of these topics and how they interrelate. Excellent for cross-training of other technical disciplines such as reservoir and surface facility engineers plus geoscientists, and anyone who interacts with drilling, completion or workover design engineers such as technical supervisors and technical service personnel. This is not a fundamental course for training engineers seeking a career in drilling or workovers (for these,PO1 is recommended).
