Wear concentrates where contact force is highest, which means doglegs. A string rotating through a sharp dogleg applies a side force proportional to tension and dogleg severity, and the wear rate follows that force and the rotating hours. The same well drilled on a smooth trajectory and a tortuous one will have very different wear, which is one more reason trajectory quality matters.

Hardbanding is both the solution and part of the problem. Modern casing-friendly hardbanding protects the tool joint while limiting casing wear; older tungsten carbide hardbanding protects the tool joint by wearing the casing instead. Knowing what is on the pipe being run inside a critical casing string is a basic check that is sometimes missed.

Wear matters because it reduces strength. A casing string that has lost a significant fraction of its wall has lower burst and collapse ratings, which affects well control limits, future operating pressures and abandonment requirements. Prediction during planning and verification by inspection afterwards are what keep the integrity case honest.

By the end of this training, participants will be able to:

• Explain casing wear mechanisms and the conditions that cause them.
• Apply contact force and wear factor concepts.
• Predict casing wear from trajectory, tension and rotating hours.
• Identify the data required for credible wear prediction.
• Assess the effect of hardbanding type and condition on wear.
• Select casing protectors and assess their effectiveness.
• Assess mud type, lubricity and solids effects on wear rate.
• Specify wear measurement and casing inspection methods.
• Calculate remaining casing strength after wear.
• Manage wear through well design, drilling practice and monitoring.

The course is instructor-led. Wear prediction is developed with calculations applied to real well trajectories and drilling programmes, and compared with caliper inspection results from the same wells. Hardbanding and protector performance are covered with field data. Participants are encouraged to bring their own well designs and inspection logs for discussion.

Organisations sending participants to this training will:

• Predict casing wear before it compromises well integrity.
• Protect critical casing strings in extended reach and deep wells.
• Select hardbanding and protectors that reduce wear.
• Verify casing condition and remaining strength by inspection.
• Adjust well design and drilling practice to manage wear.

Participants will:

• Understand how and where casing wear occurs.
• Be able to predict wear for a planned well.
• Understand hardbanding and protector selection.
• Be able to assess remaining casing strength.
• Be able to specify inspection and monitoring programmes.

• Drilling and well engineers
• Well integrity engineers
• Completion engineers
• Tubular and inspection specialists
• Rig site supervisors
• Technical authorities reviewing well designs

Upon successful completion of this training course, delegates will be awarded an official Certificate of Completion issued by the Petroleum Engineers Association (PEA), an ISO 9001:2015 certified training organization. The certificate carries 10 Credits and formally records the total learning hours completed.

Each certificate is signed by the Course Facilitator and the CEO of the Petroleum Engineers Association, and serves as verifiable proof of professional training that delegates can present to employers and professional bodies worldwide.
