Method and apparatus for lifting liquids from gas wells

摘要

A downhole apparatus for lifting liquids from gas wells comprises constriction or throat section 15 such as Venturi in which a production gas from the well is used to generate a low pressure zone having a pressure less, and at least a conduit 16 providing a flow path from an up-stream location within the well to a low pressure zone. The conduit may have additional opening 163 for production gas to enter the conduit 16.
