Abstract
A downhole apparatus and method for maintaining or reducing the level of liquids at the bottom of a gas producing well is described including a constriction or throat section, such as a Venturi, in which a production gas flow from the well is used to generate a low pressure zone having a pressure less that the ambient formation gas pressure and at least one conduit providing a flow path from an up-stream location within said well to said low pressure zone. The conduit may have additional opening for production gas to enter the conduit.
