A Simple Method for Data Processing of Surface Dynamometer Card

The surface dynamometer card is considered as the primary data for a computer analysis of a sucker rod pumping well. There are many problems in the information retrieved from the surface dynamometer card involving duplicated data and reverse direction data (RDD) ,and discontinuous data of the upstroke or the downstroke , etc. This paper presents a simple method for data processing of surface dynamometer card,it is very useful for the dynamics analysis and structural optimization design of pumping unit (PU).
