We recently made a few improvements to our 4.5" casing plunger which were based on a successful
trial by National Oilwell and the worn plunger that we exchanged with them. These improvements
were small but significant to the reliability of the system. We have always been confident in
our design through testing in our well simulator but now we have proof that we have a reliable
casing plunger design.
If you would like to know more or to test a system on a trial basis please
