The Purpose of the Completion
The well completion is the installation that enables production of fluids in a safe and efficient manner.

Ideally, the lowest cost completion (considering both initial and operating costs) that meets the demands placed upon it for the well life.

Reservoir Management Tool
The choice of completion concept is dictated by:
The reservoir model and operator’s drainage strategy.
