CEO Four Plunger-Lift Controller Overview

eP’s CEO Four plunger-lift controller is designed to meet remote requirements by using ultra low-power electronic technology. The CEO Four controller's design incorporates all the proven SCADA and remote-terminal-unit (RTU) functions of other wellsite intelligence products, making it the most complete and advanced plunger-lift controller available in today's marketplace. This state-of-the-art controller is designed with a programmed on cycle initiation calculation accounting for casing, tubing and line pressures, as well as for annulus volume, fluid load and tubing frictions. The CEO Four controller can also be used to monitor tank levels.

The CEO Four controller offers a broad range of control mechanisms: time-based, using system pressure inputs; pressure-based; single-, dual- and triple-valve; and flow rate and differential pressure.

Applications of the CEO Four Plunger-Lift Controller

• Simple plunger-lift operations
• Advanced pressure-based plunger lift and intermittent control
• Complete plunger automation projects
• Stand-alone optimization
• Rod-pump optimization
• Soap-injection optimization

CEO Four Plunger-Lift Controller Features, Advantages, & Benefits

• MODBUS™ communication protocol enables the controller to poll and centralize information from local smart peripherals, reducing the complexity and cost of wellsite configuration.
• A single radio retrieves all necessary information from the wellsite, reducing operating expenses.
• Simple controls and settings allow for easy configuration, minimizing the potential for operator error.
• eP’s patented casing-to-tubing differential-optimization routine maximizes well output and minimizes average casing pressure.
• Multiple on/off function allows the operator to control the well using multiple inputs and configurations to client preferences.
• Emergency shutdown enhances safety.
• Pressure-logger mode records and enables download of data from six analog inputs, maximizing the operator's ability to analyze and optimize the well.
• Single integrated package design withstands harsh environments, providing superior control from even remote locations.
• The CEO Four controller is able to interface with most host systems, using radio (licensed spread spectrum and Ethernet), satellite and cellular channels for communication that use industry-standard protocols.
• Menu-driven interface and local display provide on-location access.
• Optional password protection discourages improper use.
• AGA 3 and 8 calculation provides non-custody transfer flow measurement.
• Easy self-optimization feature calculates the casing pressure needed to ensure arrival, based on casing size, tubing size, flowline pressure, and load size.
• Controller supports Siemens model 1000 and ROS model 200 tank gauges.
• On-extension option for failed plunger arrivals ensures necessity of b-valve and avoids venting in case of plunger switch failure.
• Persistent pressure timers ensure that cycles occur based on consistent conditions and not on unstable values.
