Abstract

There is disclosed a method of initiating production of hydrocarbons from a well having a column of liquid to provide a hydrostatic head. The method comprises inserting a tubular member inside a casing to a required depth in the liquid to define a chamber, then sealing the chamber from the outside environment. A gaseous material is then supplied under pressure to the chamber to create a pressure differential between the chamber and the outside environment, and cause the liquid to be displaced and flow along a flow conduit. The displaced liquid is collected and the casing perforated to enable hydrocarbons to flow. An apparatus is provided and includes a tubular member for insertion into the well casing, means for sealing the chamber, gas supply means to supply gas under pressure to the chamber, fluid flow means to allow collection of displaced liquid, and means to perforate the casing.
