Application of oil well casing in sulfur-containing gas wells: Selection logic of L80, C90, and T95

Keywords :oil well casing        Update : 2026-10-19        View(s) : 51

Selecting the right casing for sulfur-containing gas wells is critical because hydrogen sulfide (H₂S), high pressure, and corrosive fluids can cause sulfide stress cracking and premature failure. API 5CT grades L80, C90, and T95 offer different yield strengths, but higher strength alone d...
