R&M Energy Systems provides a complete set of products and services for optimization, monitoring, and control of Progressing Cavity Pump (PCP) installations.

PCP Speed Controller

Guardian II is a Variable Speed Drive (VFD) specifically designed to operate PCP systems in the harshest of conditions with maximum efficiency and flexibility.  Integrated inside the Guardian II is a PCP Speed Controller.  This integration with the VFD and PCP Speed Controller means the Guardian II is ready to take on demanding tasks with simple startup steps.

The PCP Speed Controller was designed to minimize downtime and to provide the logic and control functionality needed to diagnose, prevent, adjust, and repair problems that may occur in the field without multiple trips to the site.  Performance and production information is stored in a local (onsite) data repository which can easily be displayed in a simple browser-based user interface.  When automated action is taken, detailed information is captured and retained for an extensive period of time.  This can be used as an analysis aid to determine if the action was correct or if any operational parameters need to be adjusted.

Pump optimization is implemented in the Guardian II system to maximize the production available while still maximizing pump life.  R&M Energy Systems provides a variety of downhole and surface sensor systems that easily integrate with the Guardian II system.  Customer provided systems can be integrated by using built-in input terminals that can interface with virtually any system currently available.

PCP applications can be very dynamic and change in a manner of seconds.  Guardian II has been built by using the vast pumping and control experience of R&M Energy Systems.  It has built automation systems that provide the safe operating conditions and high pump run life expected by demanding customers.

PCP Speed Controller provides multiple control strategies and layers of protection.  Pump efficiency, fluid gravity, well deviation, well depth, flow line pressure, intake pressure, and fluid temperature are just a few factors that can impact the effectiveness of control logic.  By automatically adjusting the control logic to account for these and many other factors, R&M Energy Systems can provide a superior PCP Speed Controller that does not require constant attention of field personnel.  

Communications

Guardian II can easily be implemented into existing SCADA networks.  If required, it can adapt its setup to appear as any type of legacy system currently implemented, which reduces the effort required to configure backend systems for PCP monitoring and control.

Guardian CommunicateNow is a hardware and software service provided by R&M Energy Systems that provides complete communication systems for transmitting performance information or for stopping, starting, and adjusting operating parameters in real time or near real time operating modes.  By utilizing proven satellite technology R&M Energy Systems can provide monitoring and control services to your computer without any additional infrastructure build out. 

Performance Monitoring

Guardian OnSite provides a suite of software and services that permits field operators to monitor and manage key aspects of all pumps deployed.   With Guardian OnSite, operators can quickly assess the status of a field, drill down on problems, and review detailed performance data from an easy to use application.  If problems occur, a responsible party or group can be notified when the pump is not operating within the specified condition by email or text messaging.

Guardian OnSite is designed to retain a central repository of detailed performance information collected over an extended time frame.  This permits engineers and operators to review operational efficiencies and locate trends to predict problems or analyze the effectiveness of changes made to a pump’s operating parameters.  In addition to retaining and retrieving long term performance data, Guardian OnSite provides a real-time view of all monitored pumps. 

Pump performance data is collected in a variety of methods, which include serial MODBUS, serial MODBUS over data radios, MODBUS over TCP/IP, and MODBUS over Satellite.

More than just monitoring, Guardian OnSite provides two-way communications between the operator and the pump, permitting adjustments in operating parameters or remote start / stop of a pump when a communication network is deployed. Optional cameras can be added to the monitoring service to help diagnose faults without having to visit the site and helps assure site safety and environmental procedures are being applied.
