Plunger Lift

Plunger lift, gas lift, (GAPL)(PAGL), and sucker rod pumping are a few common forms of artificial lift that are heavily reliant on valves to maintain a seal in the system to extract fluids efficiently from the wellbore. 

This paper will outline the increase in well production performance when using a horizontal check valve on wells with Gas Liquid Ratios (GLR’s) conducive to plunger lift systems installed optimally in horizontal wells, also highlight design improvements when using these same valves in vertical situations.

The I-Plunger is designed for Gas Wells and is an Instrumented Plunger that records pressure, temperature, depth, and plunger velocity. Information from the tool is collected and graphically presented for detailed analysis as well as a quick reference guide.

QSO Inc. has developed a product to provide a unique and simple solution to problematic or inefficient plunger lift systems installed in horizontal wells in the USA. QSO’s Patented* Horizontal Check Valve (HCV) has removed the limitations that once burdened the industry in not being able to hold fluid properly in a horizontal well. Our HCV has proven to hold fluid in wells where conventional check valves start failing.

Plunger Assisted Gas Lift (PAGL) in the Permian Basin Over the last few years Gas Lift has become a popular artificial lift choice for producing unconventional wells in the Permian Basin. Gas Lift is a good choice for producing wells with high bottom-hole pressures (BHP) and high gas liquid ratios (GLR). Gas Lift is also a good choice for wells that produce solids or have deviated wellbores. Gas Lift however like all artificial lift choices has an optimum range which typically tends to be above five hundred barrels per day.
