Paper: New Dynamometer Technology Allows Quick Setup Easy Operation

Dynamometers have been used for many years to analyze beam-pumped wells. The evolution from mechanical systems to modern computerized systems have provided the industry with sophisticated dynamometers for the diagnosis of wells. Typical modern systems require significant capital outlay and specialized training for proper operation; this has limited the use of dynamometers for well analysis. This illustrates a need in the industry for a simple, accurate dynamometer data-gathering tool which is easy to setup and use. This paper describes a new self-contained system which can record surface and pump cards on a well within minutes of arrival at the well. It automatically calculates inferred production based on the pump card. It also allows the operator to record valve checks, counterbalance, and perform pump leakage calculations without an on-site computer. All data can be brought to the office and transferred to a desktop computer for a more detailed analysis if needed.
