    Abstract: A method for purging accumulated liquids from within and around a well bore in a petroleum well comprising the steps of: shutting off the well for a period of time to allow pressure to build up; fractionally opening the well for a period of time to allow the built up pressure to cause the accumulated liquids within and around the well bore to migrate to within the production tubing of the well; and then, fully opening the well flow line to purge the collected liquid hydrocarbons from within the production tubing. In a preferred aspect of this invention the method further comprises the step of positioning a plunger in a bottom portion of the production tubing prior to fractionally opening the well so that the accumulated liquids will collect above the plunger and subsequent purging will be more efficient.
