Troubleshooting – Well Testing Artificial Lift
Program Overview
When an artificially lifted well underperforms, the cause may lie in the reservoir, the lift system, the completion or the surface facilities, and well test data is often the first evidence available. This programme develops a systematic troubleshooting approach for electrical submersible pumps, gas lift, rod pumps and progressing cavity pumps, combining production tests, inflow performance, nodal analysis and lift-specific diagnostics such as ESP amp charts, dynamometer cards and gas lift pressure surveys to locate problems and select corrective actions.
Learning Outcomes
- ✓Validate a production well test and identify unreliable test results before using them for diagnosis.
- ✓Construct inflow and outflow curves and use nodal analysis to separate reservoir and lift limitations.
- ✓Diagnose ESP problems from amp charts, intake pressure and motor temperature trends.
- ✓Interpret gas lift pressure and temperature surveys to identify multipointing, valve failure or insufficient injection.
- ✓Analyse dynamometer cards to detect fluid pound, gas interference and rod or pump failures.
- ✓Recommend corrective actions ranked by production gain, cost and intervention risk.
Target Audience
- Production and petroleum engineers
- Artificial lift specialists and field optimisation engineers
- Well testing supervisors and production operators

Training Methodology
Applied Project & Assessment
Applied Project
Participants diagnose a set of underperforming wells using supplied test data, amp charts, dynamometer cards and gas lift surveys, then present for each well the root cause, the supporting evidence and a ranked corrective action plan with expected production gain.
Assessment
Short diagnostic at the start, practical tasks linked to each learning outcome, and evaluation of the applied project against published criteria.
