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.
• Weatherford’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.
