The sucker-rod pump system is the most widely used form of artificial lift for the onshore oil well production [1-3].
This paper is focused to study, compare, and select the proper feature extraction methods used to analyze the sucker-rod pump indicator card data before pattern classification.
The characteristic of rotational invariance, both in the FD algorithm and the GMV algorithm, may cause improper pattern recognition of indicator card data when used for sucker-rod pump working condition diagnosis.
R&M Energy Systems has released the Guardia[TM] Sucker-Rod Pump
Controller SRP[TM] as an addition to the Guardian product line of effective digital solutions for production control.
It is almost 75 % of the one million wells utilizing artificial lift are run with a sucker-rod pump. This popularity of this system is attributed to its durability, simplicity, and flexibility.
The action of the sucker-rod pump is presented in Figure 4 through a dynamometer card, assisting the following detailed explanation as shown by Rowlan et al (2007).
