CASE STUDY 2 - WELL ANALYST
PCP ARTIFICIAL LIFT FAILURE PREDICTION
European Operator - France
Well Analyst Downhole Event Monitor
Monitor a PCP for indications of when the artificial lift system would fail
During a Well Analyst deployment, the operator was able to identify a missed ball launch at surface that would have resulted in a sleeve not shifting, and a frac not being diverted as required. They were able to reset the frac equipment and complete a successful frac after the fault had been flagged by the Well Analyst.
Characteristic noise graphs for each type of artificial lift system can be gathered over time and when correlated with surface observations such as torque can provide a useful predictive and preventative warning to operators allowing AL units to be shut-down and worked over prior to failure, avoiding expensive fishing jobs.
