Oil Casing and Tubing: A Brief Overview

Oil casing and tubing are critical components in oil/gas wells. Casing lines the wellbore, providing structural integrity, preventing collapse, and isolating formations. Tubing, smaller in diameter, runs inside the casing to transport hydrocarbons to the surface. Both are typically made of high-strength steel (e.g., API grades) to withstand extreme pressures, temperatures, and corrosive environments. Properly designed, they ensure safe, efficient wellbore operations and long-term production.
