    Accurate Load & Position Measurement Is Critical to Quality Dynamometer Analysis Anthony Allison Abstract:  Analysis and control of sucker rod pumped (SRP) wells has changed drastically over the past 30+ years. Advanced diagnostic tools first started appearing as desktop applications. Eventually these tools shifted to the wellsite in the form of rod pump controllers to provide more accurate control of a rod pump system in real-time. All of these tools depend on a dynamometer card in order to properly analyze and control a rod pump system. However, the inputs to the dynamometer card are often of questionable accuracy. A poor quality dynamometer card can lead to improper control of the rod pump system. The accuracy of calculations that depend on the dynamometer data such as rod stress, gearbox torque, structure loading, and rod stress will also be reduced. This presentation will discuss the variety of instruments used to capture the inputs to a dynamometer card (polished rod load and position), their strengths and weaknesses, how to recognize errors in the input data, and how to correct them. The one idea I would like members to take away from this lecture is how common these measurement errors are and how to recognize and correct them to improve the operation of their rod pumped wells. Biography: Anthony Allison is an Artificial Lift Advisor for Occidental Oil & Gas, where he provides in-house support for the analysis, optimization, and troubleshooting of sucker rod pumps (SRP) globally. He has eleven years of experience with sucker rod pumping systems, specializing in the use of automation hardware and software tools to optimize the performance of SRP systems. Anthony currently serves as the chair of the 2020 SPE Artificial Lift Conference and Exhibition-Americas and chairman of the American Petroleum Institute Subcommittee 11 which oversees standards related to artificial lift equipment. He holds a bachelor's degree in Electronics Engineering Technology and master's degree in Petroleum Engineering, both from Texas A&M University.

    Science vs The Art of Gas Lift Kenneth Decker Abstract: The gas lift design technique is the result of empirical evidence gathered at the wellhead.  Because the design technique is generally successful it is believed the theories of valve performance are also correct.  Flow testing of gas lift valves has provided more accurate performance models but those models have not been incorporated into the design technique. The annulus gas balance concept will be introduced and used to explain how tested valve performance models can be used to perform analysis on gas lift wells.  Data collected from an unconventional well be analyzed and compared to traditional analysis methods. Standard practice for gas lift was developed decades ago without the benefit of modern tools and test data.  We now have the tools and data to perform more accurate design and analysis.  We should begin to change ‘standard practice’ to reflect our new understanding of how gas lift works. Biography: Ken has spent his professional career working with Gas Lift and particularly the flow performance of gas lift valves.  That career has spanned 40 years working with Merla, Otis, and finally Decker Technology, Inc.  He served as the chairman of the original API 11V2 RP document that defined how gas lift valves are to be tested.  The Valve Performance Clearinghouse (VPC) was created and administered by Ken for 17 years before being donated to Louisiana State University.  He has consulted on gas lift projects around the world, wrote computer programs to simulate and analyze gas lift wells, written numerous SPE papers, is a regular presenter for the Gas Lift Workshop, and was named an SPE Artificial Lift Legend in 2018.
