Introduction

Deep well drilling is one of the most technically challenging and cost-intensive operations in the upstream oil and gas sector. Success requires a thorough understanding of subsurface behavior, advanced engineering techniques, risk management, and real-time operational control. This 12-day intensive training program, developed by Global Horizon Training Center, is designed to equip drilling engineers, supervisors, and field professionals with the knowledge and technical skills required to plan, design, and execute deep well drilling operations efficiently and safely.
