Program Professional Framework
ERD Drilling and Stuck Pipe Prevention
Program Overview
Extended reach wells push torque, drag, hydraulics and hole cleaning to their limits, and stuck pipe becomes a dominant risk as step-outs increase. This course covers ERD well design and feasibility assessment, torque and drag modelling, friction factor calibration, drillstring and rig capability limits, ECD management and hole cleaning in long tangent sections, casing and liner running techniques such as flotation and rotation, and a structured stuck pipe prevention programme covering differential, pack-off and geometry-related mechanisms. Examples include offshore and artificial-island developments in the Gulf where extended reach wells access distant reservoir targets.
Learning Outcomes
- ✓Assess ERD feasibility by comparing torque, drag and hydraulics predictions with rig and drillstring limits.
- ✓Calibrate friction factors from real-time hookload and torque data and update models while drilling.
- ✓Design hole cleaning and ECD management practices for long high-angle tangent sections.
- ✓Plan casing and liner runs using flotation, rotation and centralisation strategies.
- ✓Identify stuck pipe mechanisms from warning signs and apply the correct first actions.
- ✓Develop a stuck pipe prevention plan with trigger points, practices and crew responsibilities.
Target Audience
- Drilling engineers and ERD well planners
- Drilling supervisors and superintendents
- Directional drillers and real-time monitoring engineers
- Toolpushers and rig crews on extended reach campaigns

Training Methodology
Applied Project & Assessment
Applied Project
Participants assess an ERD well proposal from a provided Gulf case, run torque, drag and hydraulics checks against rig limits, and deliver a stuck pipe prevention plan with trigger points, operating practices and a casing running strategy.
Assessment
Short diagnostic at the start, practical tasks linked to each learning outcome, and evaluation of the applied project against published criteria.
