Well Engineering: Torque and Drag and Hydraulics
Format and Duration:
2 days
4 sessions
This course provides a comprehensive treatment of torque and drag forces, as well as wellbore hydraulics, grounded in theoretical principles and practical applications. Participants will learn the basics of friction factors and how to estimate torque and drag forces, including hookload calculations and tubular buckling concepts for both 2D and 3D scenarios.
It will also focus on drill bit hydraulics, covering drilling mud composition, properties, and functions, along with various rheology models.Participants will be introduced to different hydraulic pump and nozzle optimization methods, each with distinct objective functions.
Additional topics will include hole cleaning, selected empirical correlations and models for deviated wells, with an emphasis on addressing practical drilling problems, as well as understanding surge and swab effects.
Business Impact: This course enhances operational efficiency, improves well design, and reduces drilling costs by equipping engineers with advanced knowledge in torque/drag, hydraulics, and high-angle well operations. It minimizes non-productive time, improves safety, and reduces risks, while optimizing resources and addressing complex drilling challenges. This leads to cost savings, better project outcomes, and a competitive advantage.
