Rod Pump Optimization - Midland, TX - April 8-11, 2019
This course covers artificial lift fundamental principles including advances and disadvantages of most commonly used artificial lift systems (Rod Pumping, Gas Lift, Hydraulic, ESP, and PCP). It primarily covers modern rod pumping system optimization and the knowledge you need to understand how rod pumping systems work, how to design and analyze them, and what affects their performance. Since a failure in any part of a rod pumping system will result in production loss and is expensive to repair, this course will cover all subjects related to proper equipment selection, system design, diagnostic analysis of existing systems, pumping unit balancing, and in general, all techniques that minimize failures and maximize system efficiency.
The RPO Course covers:
- Rod Pumping advantages and disadvantages
- Effect of system efficiency on lifting costs
- Pumping unit geometries and prime movers.
- Downhole Equipment: Common and special pumps and their advantages and disadvantages.Plungers; balls and seats; pump displacement and slippages; gas anchor design.
- Field Measurements: Dynamometer cards; counterbalance effect; amp plots; traveling and standing valve checks.
- Torque Analysis and Balancing: Calculation of net gearbox torque; construction and application of the permissible gearbox load diagram; modern pumping unit balancing.
- Sucker Rod String: Stress analysis of API and non-API steel rods; advantages and disadvantages of fiberglass rods and Corods; sinker bars; Ribbon Rods; rod failures.
- System Design: Constant productivity index, Vogel, and Fetkovich IPR methods; wave equation versus API RP 11L predictive methods; guidelines for system design;tips for reducing torque and rod loading, and increasing system efficiency.Hands-on system design with RODSTAR (a modern wave equation predictive computer program).
- Dynamometer Analysis of Existing Systems: Surface versus downhole dynamometer cards; recieve in-depth explanation of downhole dynamometer card shapes; how to understand downhole dynamometer card shapes. Hands-on system analysis with RODDIAG using dynamometer cards from actual wells.
- Fluid Pound (Problems and Solutions): Cause of fluid pound and steps to minimize it;percentage timers versus pump off controllers; fluid pound detection methods;centralized pump off control.
- New Technology Developments: Expert systems and other new developments for optimizing rod pumping systems; the XDIAG computer program and its applications.
After completing this course, you will be able to use modern rod pump technology effectively to optimize rod pump systems. You will learn how to design rod pump systems, compare pumping units, and more. In-depth dynamometer card interpretation will enable you to diagnose and fix field problems. Many field examples will be used for practice.
