Pacemaker Plunger Co.
Their Problems / Our Solutions
Plunger lifts are a well known method of keeping “low bottom hole
pressure” gas wells unloaded and keeping tubing (or casing in wells with no tubing)
from building up fluid that hampers or stops the flow of gas to the surface.
The following is a list of problems with
existing plunger lift systems and our Pacemaker solutions.
- Problem 1. Having to shut wells in to allow the
plunger to drop to the
bottom, due to the lack of bypass on the existing plunger systems.
- Solution: The Pacemaker two-piece plunger is
designed to trip to the bottom while the well is producing at a substantial
rate. In some wells, the plunger
falls to the bottom while the well is producing at 1,000+ mcf/day.
- Problem 2. Some wells have
more shut-in time than open time to allow gas pressure to build to the point where the
pressure will lift the plunger and any fluid in the tubing to the surface.
- Solution:
Pacemaker's plunger requires only a few seconds shut-in time because it
can trip to the bottom and back at speeds of 1,000 ft./1 min. or faster while the well is
flowing at a substantial rate. The high speed round trip allows the plunger
to lift smaller amounts of fluid with each trip so it can clear more fluid
per day with less bottom hole pressure than conventional plunger lift systems.
- Problem 3.In many wells
it is necessary to remove the packer or perforate the tubing above the packer, so the
casing annulus can be used as a pressure bottle to drive the plunger and well fluid to the
surface.
- Solution:
The two-piece plunger system performs very well without using the casing
annular volume. Pacemaker's plunger relies more on volume than trapped pressure to
trip the plunger to the surface. The two-piece plunger works well in a 2 7/8"
slim hole or wells with a packer and no communication with the annulus.
- Problem 4. Wells with
traditional plunger systems and on-site compressors can be problematic due to the long
shut-in periods necessary.
- Solution:
Wells with on-site compressors are usually adapted easily to the Pacemaker
plunger because the shut-in time of only seconds has almost no effect on the
suction pressure of the compressor. A shut-in time of only seconds
also creates more stable well head pressures.
