Drilling & Well Construction

Basic Drilling, Completion and Workover Operations

Introduction

This course is specifically designed to give a technical overview of the science and art of drilling operations, completion practices and post-completion wellbore enhancement or remedial workover techniques (well intervention). Its purpose is to develop an understanding of the WHAT, WHY, and HOW of each of these areas of engineering practice. The participants learn to visualize what happening downhole is, discover what can be accomplished and gain an appreciation for wellbore risks and the possibility of damage to the formation. How drilling and completion practices can alter reservoir interpretation and performance will be discussed. The participant will become conversant with specific technical terminology and aware of practical applications, which should enhance communication and interaction between disciplines.


Objectives

By the end of this course participants 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

Target Audience
  • The course is directed to all technical, field, service, support and supervisory personnel desiring to gain an introductory overview of these topics and how they interrelate.
  • The course is also excellent for cross-training of other technical disciplines such as reservoir and surface facility engineers plus geoscientists.
  • Also helpful for anyone who interacts with drilling, completion or workover design engineers such as technical supervisors and technical service personnel. 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.
