Solution Overview

Problem

Traditional methods for recalibrating electrical submersible pump (ESP) design parameters are tedious, error-prone, and inefficient, often requiring manual trial-and-error processes to match ESP performance data with SCADA measurements, making it difficult to identify optimal design parameters for thousands of models.

Innovation Solution

An automated system using a Self-Organizing Map (SOM) and averaging analysis to generate training data sets, cluster similar data rows, and recalibrate ESP model input parameters to match measured output parameters within error tolerances, reducing human intervention and improving accuracy.

VSEngineering Contradiction Analysis

1Reliability

If manual trial-and-error methods are used to adjust ESP design parameters, then the process allows for human judgment and flexibility, but the process becomes tedious, error-prone, and inefficient when updating thousands of models

Engineering Contradiction:

Solution Approach 1:

The patent replaces the manual mechanical process of trial-and-error parameter adjustment with an automated computer-based system that uses algorithms to systematically modify design parameters and match SCADA measurements, eliminating human error and dramatically increasing throughput capability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service automation where the computer automatically performs parameter recalibration without human intervention, allowing thousands of models to be updated independently and simultaneously, transforming a labor-intensive process into an autonomous computational task

Inventive Principle:
Principle #25Self-service

2Measurement precision

If manual analysis is used to identify optimal design parameters, then the analyst can apply expert judgment, but it is unlikely that the analyst will be able to resolve the data sufficiently to identify the design parameters that provide the closest possible match to SCADA measurements

Engineering Contradiction:

AI summary

Apparatus, computer readable medium, program code, and methods for performing a parameter recalibration on parameters for an electrical submersible pump application model, are provided. An example of a method can include generating a data set containing a plurality of winning data sets or rows containing 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, through application of a self-organizing map analysis on a substantial number of training data sets. An averaging analysis is performed on the plurality of winning data sets or rows to obtain a set of ESP application model input parameters that can be used to recalibrate the ESP application model.
