Course Description
for
Advanced Sucker-Rod Pumping
Presented by
Dr. Gabor Takacs
Course Duration: 5 days
Course Description:
The course will follow the latest book written on sucker-rod pumping theory and practice by the instructor (a copy of the revised book is distributed among trainees). After a short description of the pumping system, the design of its most important part, the rod string, is thoroughly discussed. Using computer programs, trainees will be able to compare the different design principles and their pitfalls. When introducing the surface pumping unit, the proper calculation of their kinematic parameters is shown and the relative advantages of different pumping unit geometries will be highlighted. Next, the API RP11L procedure is discussed in detail. Trainees will make several example calculations to find the most important operational parameters of sucker-rod pumping installations. Counterbalancing of pumping units is important in daily operations, this is why calculations will be introduced for finding gearbox torque loads. Optimum counterbalance conditions will also be found. The optimization of a sucker-rod pumping installation for maximum power efficiency will be shown next. Through the analysis of the energy flow in the pumping system and computerized sample calculations, trainees will see the wide range of possible efficiencies for a single installation thereby realizing the importance of optimization. The course is rounded off by a detailed treatment of dynamometry principles and the calculation and analysis of downhole dynamometer cards.
Throughout the course, examples and class problems will be solved on the computer available to trainees who are required to have a basic computer literacy.
After completion of the course, trainees will:
· Have a better understanding of sucker-rod string design options and be able to select the right design process for their fields.
· Have a working knowledge of RP11L calculations and be aware of its limitations and possible improvements.
· Be able to properly counterbalance a pumping unit.
· Understand the grave importance of optimizing the complete pumping system and be able to find the most energy-efficient conditions for any installation.
· Understand the basics of polished rod dynamometry and the role of downhole cards in analyzing rod pumping installations.

Instructor’s Short CV:
Gabor Takacs is presently a professor and was Acting Director (2007-08) at the Petroleum Engineering Department at The Petroleum Institute in Abu Dhabi, UAE. Previously he was the Head of the Petroleum Engineering Department at the University of Miskolc, Hungary and holds MS and PhD degrees in Petroleum Engineering from the same institution. He has more than 30 years of teaching and consulting experience in the production engineering field. He taught as Visiting Professor at Texas Tech University, USA in 1988/89 and at the Mining University of Leoben, Austria in 1995. In 1995/96 he was selected SPE Distinguished Lecturer, was Outstanding Technical Editor for the SPE journal “Production and Facilities” 1992-2003, and chaired the Artificial Lift TIG (Technical Interest Group) of SPE in 1997-2003. He is the author of several books on artificial lift technology; “Modern Sucker-Rod Pumping” (1993), “Sucker-Rod Pumping Manual” (2002), “Gas Lift Manual” (2005), all published by PennWell Books, USA. His latest contribution “Electrical Submersible Pumps Manual” came out in 2009 from Elsevier. Dr. Takacs has more than 90 technical papers to his credit. He taught various short courses for many oil companies in Libya, Mexico, Argentina, Indonesia, UAE, Romania, Malaysia and Austria; and is a well-known consultant and instructor on production engineering and artificial lift topics.
