What is the name of the process used to create flow channels from a well into a reservoir by perforating casing?

• A. Perforation
• B. Casing deformation
• C. Stimulation
• D. Drilling

Answer: (A)

Creating flow channels from a well into a reservoir by perforating the casing is called perforation. After the well is drilled and the casing is cemented in place, a perforating gun is run into the well and fired. The charges create small tunnels through the steel casing and the surrounding cement, linking the wellbore with the surrounding rock so fluids can move between the formation and the well. This targeted breaching is what enables production from an interval that was previously isolated. Casing deformation isn’t used to form production channels; it would alter the casing without purposefully connecting to the formation. Stimulation is a broader process aimed at increasing flow and may include fracturing or acidizing, often conducted after perforation. Drilling is the process of creating the borehole itself, not establishing the flow path into the reservoir after casing has been cemented.
