The webinar is intended for field workers, engineers and other specialists of oil fields where wells are operated with sucker-rod pumping units.

The purpose

The purpose of this webinar is to give structured knowledge about dynamometering. To specify the purposes of such testing, tools and instruments , dynamometer cards interpretation. Demonstration of dynamometer cards analysis is in SIAMOS. Training is conducted in the form of audiovisual delivery (presentation) and subsequent discussion and answering trainees questions.


  • quality improvement of dynamometering;
  • improved monitoring of field development;
  • production loss enhancement due to prompt troubleshooting in sucker-rod pumping unit performance;
