By-Pass flow plungers can fall against the natural flow of the well or can be operated with minimal shut in time (generally less than 10 minutes). A bypass plunger system can improve your well’s production by allowing increased or continuous well operation while eliminating liquid loading. The system is designed to fall against the natural flow of the well allowing the plunger to make more cycles per day than conventional plungers. This improves the ability of the plunger to remove fluid from the tubing, and lowers that build-up of fluid slugs that can accumulate at the end of the tubing string. As a result, the system is dependent on critical flow rates vs. build-up pressure to maximize performance.
These plunger styles operate using a valve mechanism. When the plunger falls to the bottom of the well the bumper spring closes the valve to allow the plunger to travel back to the surface. Once arriving in the lubricator, the valve is actuated back open and the plunger is ready to start back down the well to begin the next cycle.
Ancillary equipment includes the pneumatic catcher (auto-catch) to manage the plunger drop cycles.
