Which Artificial Lift technologies to choose?

Historically ALS is driven by ESP’s for high flow rate and SRP’s for low flow rate. Over the last thirty years new pump technologies arrived on the market to improve efficiency and performance such as PCP’s, jet pumps,…

Operators are well educated on ESP/SRP’s and tend to keep PCP’s only where ESP’s & SRP’s don’t work.

Here below is a comparison between the three main Artificial lift technologies: Electrical submersible pump (ESP), Sucker rod pump (SRP), Progressive Cavity pump (PCP).
