Q2 and QSO have partnered up 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 up to 75 degrees of angle where conventional check valves start failing at +/- 48 degrees.
Production companies can now access current deeper profile nipple locations without the need to set their bumper springs on expensive tools higher in the tubing just to ensure a seal. By maintaining a fluid column down in the heel of a horizontal well, the plunger lift system’s efficiency is maximized, which yields an increase in both fluid and gas production, reduces the frequency of “dry” plunger arrivals, eliminates swabbing and many other remedial well operations. Most common material options are also available.

Here is a very typical well that the HCV has helped. By switching out the conventional check valve with the HCV at +/- 60 degrees and +/- 1,700 m (5,580 ft), the Operator saw a payout of less than two weeks from increased production of over 7e3m3/day (245 mscf/day) with less operator intervention time (blow downs, shut ins, Plunger inspections, swabbing.)
15-31-42-27w4 this well was a chronic well. Loading issues, struggling flow against any pressure changes at surf.
Following the HCV install in Jan 2020, the well is back on trend and continues to require next to no extra attention from operations…ongoing sustained production of over 3e3m3/day (105 mscf/day) from conventional check valve system.
