Abstract
A plunger having a generally hollow interior between an open upper end of the plunger and a closed bottom end of the plunger. One or more orifices extend through a sidewall of the plunger near the closed bottom surface. The orifices fluidly connect the hollow interior of the plunger with the tubing below the plunger when the plunger is in use. The orifices allow for a transfer of gas from the well bottom into the liquid load above the plunger during plunger ascent. The orifices also allow liquids to pass through the plunger during plunger descent.
