2. Operation Mode Mode 6 Critical Flow vs Casing Pressure Intended Use Enhanced On Off control utilizing well pressure A Plunger is not required Use of Casing pressure allows the off time to vary according to the well s ability to build pressure This mode consists of automatic On Off control based on a critical flow set point and a casing pressure value Both on and off times will vary Plunger is optional with this mode The cycle is started in the on or off time according to the Start Position The Minimum On Time Before Critical Flow Timer MOTBCF Timer will begin counting down at the start of the on cycle The purpose of this timer is to permit flow for a minimum period of time and if a plunger is installed to allow enough time for the plunger to arrive Once the MOTBCF Timer has expired the critical flow set point determines how long the well will stay open If the gas flow rate drops below the critical flow set point the Critical Flow Bypass Timer will begin counting down The control valve will remain open during this time If the gas flow rate falls below the Critical Flow set point during the Critical Flow Bypass Timer will reset and the valve will remain open If the bypass timer expires the valve will close and the program will go into the Time Off cycle The length of the off cycle is determined by the recovery time of the well the pressure value will have dropped while the well was flowing and will increase over time

Supplementary Information Target Velocity is the desired plunger arrival velocity that uses either metric or imperial units determined by the RTU configuration Target Velocity and Well Depth must be positive numbers A suggested range for plunger arrival velocity is 182 to 275 meters minute 600 to 900 feet minute A set of plunger arrival set points is available to fine control the sequence of the On Off Cycles If Maximum Early Plunger Arrivals Preset is zero the fast plunger protection functionality ius disabled Otherwise if the plunger early arrival counter exceeds its set point the program stops and sets up fast plunger arrival flag for operators intervention If Maximum Late Plunger Arrivals Preset is zero the plunger late arrival count does not affect the On Off cycle Otherwise if the plunger late arrival counter exceeds its set point the Back Up Off Cycle starts in place of the Time Off Cycle This gives the well more time to build up the pressure and let the plunger fully drop to the bottom If Maximum Failed Plunger Arrivals Preset is zero the plunger failed arrival counter does not affect the On Off cycle Otherwise if the plunger late arrival counter exceeds its set point the Back Up Off cycle starts in place of the Time Off Cycle This gives the well more time to build up the pressure and let the plunger fully drop to the bottom The Early Plunger Arrivals Time Preset and Late Plunger Arrivals Time Preset determine the lim
