What’s new in artificial lift?

Part 1: In this first of two monthly reports, the authors highlight innovations in beam/rod pumping, linear lift units, hydraulic piston pumps, hydraulic jet pumps, and more. There are probably as many ways to classify artificial lift systems as there are production engineers in the world. As a point of reference, we like to look back each year to Table 1, which we first published in this feature in May 2013. As indicated, we think it makes some sense to organize artificial lift systems into three categories: 1) pump-assisted systems; 2) fluid-assisted systems; and 3) flow enhancement techniques. Within these three categories, there are basically 11 types of lift technologies. In each category, there also exist unconventional or emerging technology types of lift.
