Objective:
This course aims to provide participants with a comprehensive understanding of drilling extended-reach and horizontal wells, emphasizing wellbore trajectory, torque-and-drag management, hydraulics, and performance optimization to maximize well quality and productivity.
Audience:
Ideal for drilling and completion engineers, drilling supervisors, technical support and subsurface teams, and project managers involved in designing or managing complex directional and extended-reach well campaigns.
Methodology:
Delivered live online, the course blends conceptual lectures with real-world exercises, case discussions, and analysis of operational challenges. Attendees engage interactively to consolidate knowledge.
Scope:
It covers the integrated planning, design, and operational techniques for drilling high-angle or extended-reach wells—addressing challenges like hole cleaning, Equivalent Circulating Density (ECD), Well Path control, and minimizing mechanical complications.
