API 5CT Casing Seamless Steel Pipes For Oil And Gas

OCTG means Oil Country Tubular Goods, which refers to steel used in oil and gas extraction and production processes, including Drill pipe, Casing, Tubing, Couplings, Connections and Accessories, for the oil and gas industry on land and offshore.

API 5CT is the most common and important standard to ensure the normal production and exploitation of oil and gas. Casing and Tubing are both used in the process of drilling for petroleum.

Casing is placed before drilling begins and completely surrounds the wellbore. Its purpose is to protect the soil layers and groundwater from contamination by drilling mud and/or frac fluids. Additionally, casing stabilizes the wellbore. Drilling and casing operations alternate – the drill string is removed at predetermined intervals and the wellbore is lined and cemented with casing.
