You have come here in the hope of learning something about the Principles of Sucker Rod Pumping. I have been studying that subject for about 20 years and I am certain that I have much yet to learn. It is quite unlikely that you will leave here knowing all that is known about that subject. Sucker rod pumping, unfortunately, is an illusion, in that it looks quite simple whereas that problems involved are extremely complicated, and little understood. And, for that reason, many things we "know" about sucker rod pumping aren't true at all. By the work "principles" we mean the truths or facts upon which other facts or truths depend. It logically follows that we must start with the most simple facets if we are to comprehend the principles involved in sucker rod pumping and from them be able to reason our way to pertinent facts and conclusions.
