TRAINING ADVANCED WELL COMPLETION AND WORKERS

INTRODUCTION

This course gives a technical overview of the science and art of drilling operations, completion practices and post-completion wellbore enhancement or remedial work over techniques (well intervention). It develops an understanding of 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 ”down hole”, 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.
