Well completion fluids are pumped from the surface, through the wellbore, to fracture and crack rock deep underground in the natural gas-bearing formations. Sand is added to completion fluids to create a natural wedge in the cracks of fractured rocks, unlocking the natural gas molecules and allowing them to flow up the well bore. Additives used in the completion process help carry the sand in the fluid, prevent bacteria and scaling, and lower the friction in the wellbore.
Completion engineers employ fracturing fluids that are designed to achieve the most efficient and productive recovery from the specific reservoir characteristics in the Montney formation.
Progress Energy has played a leadership role in helping create a fracturing fluid disclosure program. All fluids are disclosed on the website FracFocus.ca.
