https://www.engineerlive.com/content/drive-technology-could-replace-nodding-donkey-pumps Onshore oil fields traditionally use pumping systems based on rocking beams, nodding donkey or sucker-rod pumping (SRP) mechanisms. In fact, two-thirds of all the world’s oil producing wells rely on this type of artificial lift. These pumps include large moving metal parts that are hazardous to assemble and disassemble, potentially dangerous in use and which take up large amounts of space. While mechanically simple, they can have reliability issues resulting from running dry, which causes damage to expensive and hard-to-access components.
