Definitions

  • Wellbores are drilled in subsurface formations for the production of hydrocarbons (oil and gas). Modern wells can extend to great well depths, often more than 15,000 ft. Hydrocarbons are trapped in various traps or zones in the subsurface formations at different depths.

In a multi-zone well bore, it is often desired to create a flow barrier between the production zones and the upper well completion while still facilitating communication with the lower completion tools, particularly prior to running the upper completion tools.
