Paper: Practical Rod Pumping Optimization Techniques Using Computers

In an environment of low oil prices, rod pumping system optimization is more important than ever before. This is especially true for high water cut wells that account for the vast majority of rod pumped wells in the Permian Basin. To maintain profitability, rod pumping wells must be well designed to start with, and analyzed on a regular basis to detect and correct problems as soon as possible. This requires accurate data and the right tools. One of the most powerful set of tools for this purpose is modem diagnostic analysis and design software. The purpose of this paper is to present practical optimization techniques that anyone can use to optimize the operation of rod pumping wells. These techniques, although easy to understand and apply, require the use of modem rod pumping software with unique capabilities. The procedures described in this paper have been proven to work, and when applied correctly, will result in measurable improvements in system efficiency, reduced lifting costs, and extended equipment life. The computer programs used to develop these techniques are: RODSTAR - an expert system predictive computer program, RODDIAG - a diagnostic analysis wave equation computer program, and CBALANCE - a tool for obtaining counterbalance information and for aiding in pumping unit balancing.
