Progressing Cavity Pump Systems
Progressing cavity pump (PCP) systems are the preferred artificial-lift method in wells with high solids, heavy API oil, and high fluid volumes.
PCP systems use a rotor and stator system that, once turned, causes the cavities to progress upward and move fluid from the intake to the discharge end of the pump. The resulting continuous positive-displacement flow provides the highest volumetric efficiency of any conventional artificial-lift system. These systems are ideal for many environments such as heavy crude oil production, medium-to-light oil production, coalbed methane, and sand-laden, horizontal, slanted, and directional wellbores.
We offer a broad selection of PCP pumps, drive heads, automation, and system configurations that are suited for a wide range of applications.
Our leak-free, low-profile, and small-footprint surface drive head systems are ideal for production environments with safety and environmental concerns. These systems use a proprietary centrifugal brake and application-specific elastomers that can produce from a diverse range of wellbore environments and prevent gas lock.
Weatherford is the industry leader in artificial lift and we offer expertise in all types of PCP applications.
Our global network of experts provides the optimal system configuration, components, software, and services for your specific well conditions.
The Weatherford insertable progressing cavity pump (I-PCP) system uses the rod string to install and remove the I-PCP unit from the well.
This eliminates the need to pull and rerun the production tubing, which greatly reduces the downtime and cost associated with the following interventions:
- Replacing a failed I-PCP unit
- Changing the PCP size or geometry
- Retrieving the I-PCP unit to perform a downhole service operation
- Switching to a different artificial-lift technology
We provide wellsite intelligence with our WellPilot® system, along with downhole sensors and surface instruments designed for PCP operations.
The WellPilot flow-control technology (FCT) system prevents rod overtorque and enables the well to be pumped at maximum rates without encountering damaging pump-off conditions. The system enables further pump optimization using Weatherford downhole pressure and temperature gauges placed at the pump intake and discharge areas.
We provide desktop intelligence through our WellFlo® and LOWIS™ software packages. WellFlo models, optimizes, and troubleshoots individual wells, which enables your pump to be modeled as installed and according to the unique characteristics of the well. LOWIS life-of-well information software uses well-testing data and other information from the controller, gauges, and more to monitor, analyze, and control PCP systems.
