Expanded downhole screen systems and method

摘要

An improved system and method is disclosed for expanding a fluid permeable tubular downhole in an open hole completion. A high quality borehole is first drilled using a bottomhole assembly having a long gauge bit and a short bit-to-bend ratio. A fluid-permeable tubular is then inserted into an open-hole portion of the wellbore and preferably expanded in place. The expandable tubular may include an external filtering medium. Hydrocarbons may pass from the formation through the expanded fluid permeable tubular and into the borehole, to be recovered.
