I've seen one of those systems in east Texas many years ago. I find it hard to believe that with all the friction involved they could be all that efficient. Most oil field pumping units are driven by relatively small motors, since when properly adjusted the counter weights pretty much balance the rod load for each individual well on modern systems. (Part of my research involves numerically modeling oil pumping systems.)

On the other hand, the wells in those days were relatively shallow. I doubt they would work on most wells these day, aside from being a mile or more deep, you'd also have to make sure that safety regulations are met and that cos, etc. don't mess with them.

Still, it's interesting to see how much ingenuity was involved in figuring out how to solve problems in eras gone by. I saw a primitive system in Indonesia where they lowered a cable into a well and pulled it up by hand to get the (thick) oil that stuck to it. Hardly efficient but labor was cheap and the market for the oil was for local cooking, etc. Ingenious technique with limited resources when you think about it.
