160 psig Well Opens, Plunger rises Initial Flow bypasses the compressor Sales Line 150 psi Primary Separator 155 psi Control valve set to open below 50 psig When the well opens up, initial gas volume and pressure will bypass the compressor and go into the gathering system. As pressure declines, the compressor will assume control and pull the static line pressure down that the well is working against to raise the plunger.
45 psig After Flow Period Primary Separator 40 psi As well pressure declines, compressor takes over and pulls well down to near suction pressure 155 psi Sales Line 150 psi 35 psi As the WH pressure declines the PLC will sense and the compressor will turn on helping the plunger reach the surface. After plunger arrival an after flow period begins and the compressor continues to pull the wellhead pressure down.
5 psig Well closes, Plunger falls Sales Line 150 psi Primary Separator 30 psi After the plunger falls and the WH valve shuts, the FX compressor will go into recycle mode until the next plunger cycle on the PAD In the event of a well or PAD SI, the compressor will sense loss of suction pressure over extended period and shut itself down.
Well SI to build pressure Advantages Sales Line 150 psi Primary Separator 30 psi The cycle is repeated and provides: Less differential pressure needed between Csgand Tbgto cycle plunger Thereby reducing backpressure on formation allowing more fluid entry More plunger cycles per day are achieved Increased production of Oil and Gas
Increased Frequency of Plunger Cycles over 2 Hour Period for a Niobrara well 1 2 3 CP480 TP300 Static130 1 2 3 4 5 CP300 TP230 Static80
Logix PLC uses algorithm to respond to plunger control box signals Using well s flowing pressure to determine when to utilize or bypass compression Higher frequency of plunger cycles by reducing differential pressure needed between Tbg and Csg Compressor lowers upstream static pressure and holds it constant to allow stable plunger velocity Compressor will alarm and shutdown upon well or sales line shut-in condition
Compressor stays in auto mode and pulls down sales line pressure as wells cycle their plungers. Between plungers the FX compressor goes into recycle. It will shut down if suction pressure falls below set point.
