Choke Erosion Monitoring

Software that reduces NPT and enables timely decisions

The ability to assess degrees of erosion in plug and cage control chokes operating in high sand producing wells is required to meet operators’ need to proactively plan for equipment maintenance and avoid catastrophic choke failure. Cameron recently developed and fielded the Choke Erosion Monitoring Program, a software system that adds the element of analytics to choke data capture. The program monitors the state of control choke deterioration from erosion in the field and reduces unplanned downtime. It allows the operator to make timely, proactive decisions

In a recent field trial, a major operator observed the benefits of the erosion monitoring program on their most prolific wells. The collected data also identified other problems such as restrictions within the operator’s system and erratic function of the multiphase flowmeter.

The Erosion Monitoring Program uses a traffic light display in which choke status is intuitively communicated through the level of deviation between actual and calculated CV values categorized either as acceptable, warning, or high risk. The system is made up of position, pressure, and flow sensors that route data through a Distributed Control System/Master Control Station to generate a real-time curve and software analysis.

Algorithms have been generated based on Cameron’s years of experience sizing chokes and utilizing ISAS75-02 equations. We reviewed field data from our large installed base of chokes and generated acceptable operating criteria and implemented these requirements within the algorithms.
