2000 Rod Pump Controller (RPC) Overview

eP is the industry leader in providing rod pump control products and services, with thousands of rod pump controllers (RPCs) installed and operating worldwide. A segment of eP’s artificial lift control and automation solutions, the Model 8800 RPC, is designed to operate a sucker rod pumping system in the most efficient way while also monitoring pumping system problems.

The 8800 RPC is easy to use by field personnel. The display provides readily understood messages relating to pumping system conditions. The keyboard is simple to use with dedicated keys for critical functions, e.g. “CLEAR ERRORS”. No computer codes, special skills or additional equipment are required.

The firmware is backward compatible with all RPC models 8650/8700 and central software systems, providing total turnkey solutions for virtually every oilfield automation problem.

With any pumping system malfunction, the fault lamp on the controller enclosure will flash and the controller will display the corresponding flashing fault and action messages so the operator can quickly and easily analyze the situation. Time consuming trouble shooting guesswork is eliminated.

Features of the 8800 Rod Pump Controller (RPC)

Designed for reliable operation

• Conformally coated boards provide extra protection from sour gas, humidity, salt air, and other damaging environmental conditions.
• Wide voltage input operating range protects the controller against field power spikes and sags.
• Broad operating temperature range ensures continuous operation under extreme weather conditions.
• Protection from lightning and other high voltage transients.

Easy to use

• Easily understood messages and simple to use keypad. No additional equipment needed for configuration or viewing of parameters.
• Automatic setup for many well applications.
• Operator selectable set points and actions for each fault condition.
• Built in well weighing, standing and traveling valve checks without additional equipment.
• Parameters and data stored in redundant non-volatile memory for protection from power loss.

Modular design for future upgrades

• Multiple operator interface options.
• Flexible auxiliary I/O options.
• Field communications and I/O options.
• An optional dual channel RS-232/RS-485 serial expansion card can be used to scan other devices.

Unique features

• Air balance control option automatically balances air balanced units.
• Cellular digital packet data (CDPD) compatible.
• Peak energy control option can inhibit pumping operation during peak periods of high energy cost.
• Motor restart protection prevents motor restart when condensation is present on motor windings.
• Controls virtually any pumping equipment, including improved geometry units, long stroke units and two-stage pumps.
• Power fail recovery method automatically pumps well down after power returns.
• Programmable I/O for unique monitoring and control applications.
• Fluid pump stroke determination allows gross measurement of produced fluids in shallow wells. This information is stored instantaneously, daily and historically for 29 days to allow trending of production data.
• Automatic idle time adjustment feature allows controller to adjust the off-time between cycles automatically as well conditions change

8800 Rod Pump Controller (RPC) System Operation

• Monitors load and position by means of sensors mounted on the pumping unit.
• Develops dynamometer cards from load and position data for use in controlling the pumping unit.
• Compares dynamometer data against pump-off limits entered by the operator, and stops the pumping unit when pump-off limits are exceeded.
• Idles the pumping unit for an operator selected idle time or a calculated idle time based on our automatic idle time algorithm to maximize reservoir inflow.
• Automatically restarts the pumping unit at the end of the idle time period, to pump the well fluids which flowed into the wellbore during idle time.
• Monitors all input data to determine whether maximum and minimum load values, pumping unit cycle run time, daily run time, or other operator set point limits have been violated.
• Implements an operator selected action (“FAULT LAMP ONLY”, “SOFTWARE TIMER”, “CONTROL TRANSFER”, or “OFF UNTIL RESET”) when an operator set point limit is exceeded, and provides a fault message to indicate the problem and the action taken.

Benefits of the 8800 Rod Pump Controller (RPC)

• Maintenance costs are reduced. Rod parts, tubing wear, gear box, and pump failures due to fluid pound are virtually eliminated.
• Production is maximized. Pump run-time is monitored to detect pump wear and tubing leaks, allowing preventative maintenance to be taken before production is lost. Also since problems are quickly detected, downtime due to failures is minimized thereby maximizing production.
• Energy is saved. The pumping system operates only when the pump is full. No energy is wasted by operating when the pump only partially fills.
• Manpower is utilized more efficiently. The 8800 RPC eliminates time spent checking wells that are operating properly and helps direct attention to wells that have problems.

RPC Software for the 8800 Rod Pump Controller (RPC)

RPC Configuration Manager Software

The RPC Configuration Manager software is an easy to use Windows program that can be run on most PCs. It allows users to configure the controllers in a user-friendly environment and to view and store dynagraph data, historical run times, and other data useful to well and pump performance analysis.

Dynagraph data can be exported in file formats compatible with popular downhole and net torque analysis tools.

The RPC Configuration Manager software can be connected to the controller and operated without interfering with the normal host communication.

CACService™ Software

An OPC (Ole for Process Control) server package is available to allow third party software packages to be designed to communicate with RPCs using their efficient native protocol through an industry standard software interface.

ActiveX controls are also available to easily integrate RPC Dynagraph access and direct user interface to controllers into third party software utilizing the OPC server.

As the RPC Configuration Manager software is itself based on an OPC server, it can be easily embedded into systems using the OPC server.

Remote Optimization Software

eP offers optimization software in its host-based automation software systems. The software communicates with the RPC through radio, satellite, cellular, or hard-wire. The software provides down-hole analysis for an accurate analytical look at the pump, management by exception displays for quickly finding problems, and a design tool that uses historical well information that allows the operator to design the most compatible pump system for the well.

Third Party Software

In addition to eP’s automation software, the 8800 RPC is closely integrated with many of the industries leading monitoring and analysis software packages. With multiple protocols available, the 8800 RPC allows easy integration to any system.
