ABSTRACT:
A method for extracting accumulated material from a well bore includes pressurizing gas recovered from the well bore and disposing an extraction string in communication with a sump. The sump is disposed to receive liquid from the well bore. The method further includes sealing the sump and injecting at least a portion of the pressurized gas into the sump such that at least some of the liquid in the sump is driven upward into the extraction string.
