Paper: HYBRID CASING PLUNGER REMOVES FLUID FROM GAS WELLS PRODUCING FROM MULTPLE PRODUCTION ZONES

Recent innovations and repeated successful applications using the multiple patented PAL PLUNGER casing plungers suggested extending the applications to stripper gas wells that produce from multiple production zones and/or from wells with casing having obstructions that restrict proper placement of down hole landing stops. The new HYBRID CASING PLUNGER, successfully installed and retrieved using a standard swab rig, removes well bore fluids from multiple production zones. The standard PAL PLUNGER was coupled with a unique down hole compression packer and fluid isolation assembly to permit well bore fluids to be lifted by gas flow to above the packer and subsequently removed from the well bore on the next plunger cycle. Bottom hole pressure data obtained shows the hydrostatic gradient to be that of the "dry" gas section of the well bore above the standing fluid level. Production data shows an increase in fluid removal and daily production rates.
