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 liquids at the bottom of said well to said low pressure zone. The conduit may be adaptable in length to provide for maintaining the flow path as the level of the liquids changes.
