Electrical Submersible Pump Design Parameters Recalibration Methods, Apparatus, and Computer Readable Medium

A method of analyzing and recalibrating parameters for an electrical submersible pump (ESP) application model, the method comprising the steps of:

• performing the following for each of a plurality of training data sets to generate a data set comprising a plurality of sets of ESP application model input parameters and associated theoretical output parameters for an ESP application model substantially matching a corresponding set of measured ESP output parameters defining a plurality of winning data sets or rows, each of the plurality of training data sets comprising a plurality of sets of ESP application model input parameters and corresponding theoretical output parameters:
• performing a cluster analysis on one of the plurality of training data sets in order to segregate the training data set into a plurality of clusters, each cluster containing a plurality of data subsets or rows from the training data set, each data subset or row in the same one of the plurality of clusters having at least similar characteristics,
• mapping the set of measured ESP output parameters to one of the plurality of clusters responsive to a similarity analysis performed on the theoretical output parameters within each cluster to identify a winning cluster, the winning cluster being the one cluster of the plurality of clusters collectively having a set of theoretical output parameters most closely matching the corresponding set of measured ESP output parameters, and
• identifying a data set or row within the winning cluster that yields outputs parameters which are the most closest to the corresponding set of measured ESP output parameters to define one of the plurality of winning data sets or rows;
• and
• performing an averaging analysis on the plurality of winning data sets or rows to obtain a set of ESP application model input parameters usable to recalibrate the ESP application model.
