Abstract:
1. A method for artificial lift system analysis, the method comprising: (a) providing production well information measured at a surface for a plurality of production wells, wherein each of the production wells is associated with an artificial lift system; (b) receiving and processing, on a computer, artificial lift system failure alerts for the plurality of production wells, wherein the artificial lift system failure alerts comprise predicted failure alerts and detected failure alerts, and wherein the predicted failure alerts are generated using a support vector machine method and the detected failure alerts are generated using a Bayesian Network method; (c) determining a relevance measure for each of the artificial lift system failure alerts responsive to the production well information; and (d) displaying a summary of the artificial lift system failure alerts in an ordering based on the relevance measure, wherein the relevance measure comprises an urgency of the artificial lift system failure alerts such that the detected failure alerts are ordered before the predicted failure alerts in the summary of the artificial lift system failure alerts.
