Progressing Cavity Pumps for Low Flow Rate Wells
High efficiency, lower-cost alternative: PMM-PCP artificial lift for low flow rate wells
- Artificially lifted low flow rate wells
- Permanent Magnet Motor – Progressing Cavity Pump (PMM – PCP)
- High efficiency for lower operating cost
- Improved reliability over rod pumping
In low flow rate wells, the choice of an efficient lift method is critical to maintaining economic viability of each well. Surface infrastructure and equipment as well as downhole system efficiency all factor into determining which form of artificial lift to use in low flow rate wells.
PMM – PCP System
In low flow rate wells, the Borets PMM-PCP system is an efficient and reliable alternative to rod pumping or gas lift operating at rates from 6 bpd to 283 bpd (362 series) and from 25 bpd to 1,182 bpd (406 series). Superior energy efficiency (and OPEX cost) is achieved using a downhole PMM to drive the pump. Even greater cost efficiency is achieved when installation of a PMM-PCP system follows use of an ESP in the same well and the same power cable and surface drive are reused.
Borets PMM-PCP systems offer unmatched energy efficiency versus other forms of artificial lift at low flow rates (as much as 40% or more electrical power savings compared to ESP systems). Run life reliability is also enhanced using a PMM-PCP since the system is not susceptible to the comparative mechanical wear risk using rod pumps associated with using a steel rod string to surface.
