What Makes A 3 ½” Dual Pad Skirted Plunger Special?
PIT is well known for our plungers. We’ve supplied thousands of plungers to hundreds of companies and are always looking for ways to improve our designs. One of the issues that come up often when dealing with our clients, is how we should handle a well with an SSSV in extreme sour wells. Our 3 ½” Dual Pad Skirted Plunger* is a solution to this issue.
When a Sub Surface Safety Valve (SSSV) is triggered it isolates the well bore. This can happen when there is a system failure or damage to surface production, control, or safety facilities. When an SSSV has finished its life on the well, it can be removed. However, the landing nipple is still in place and is either very expensive or impossible to remove.
How did PIT address these issues? Simple. We created a Dual Pad Skirted Plunger capable of compressing far more than a non-skirted plunger. When compressed, the plunger is able to slip through the nipple. That way there is no need to pull tubing to remove the nipple and no need to spend thousands of dollars in the process.
The flexibility of the Dual Pad Skirted Plunger allows it to significantly increase the efficiency of your well. Not only is it able to collapse to fit through a nipple, it also expands further than a non-skirted plunger. This allows it to create a tighter seal to reduce gas and liquid leaks while traveling through the tubing.
The plunger has to travel regularly through the nipple. This means the plunger is built with durability in mind so that it may withstand the wear and tear that comes from passing through the SSSV nipple.
3 1/2″ Dual Pad Skirted Plunger Case Study
This 3 ½” Dual Pad Skirted Plunger (pictured right) was recently replaced in one of our customer’s wells. It ran on a 13% sour gas well outside of Olds, AB. During that time it removed hundreds of liters of contaminants from the well.
PIT builds our plungers hardy so that they can withstand extremely punishing conditions. This particular plunger made 12 cycles a day through the nipple and the rest of the tubing, expanding and collapsing whenever it was needed.
