Swabbing Unit

Swabbing is a process to remove liquids from the production zone of a gas or oil well Gas and oil wells produce fluid over the life of a well. When a well is first drilled it is usually Fracked to help open production zones. Fracking can include water. After fracking, the liquids are recovered by swabbing the well. As liquids are lifted to relieve the hydrostatic weight from the producing formation the bottom-hole pressure pushes the gas and/or oil up and out of the well. Though out the life of a well liquids flow back with the natural gas or oil at a good age. If bottom-hole pressures are not enough to push the liquids out of the well, production then falls off. The well must then be swabbed or hydrostatic pressure must be reduced to maintain production.
