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) : 76

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...

Application and Selection of Oil Casing in Shale Oil and Gas Horizontal Wells

Keywords :Oil Casing Oil and Gas        Update : 2026-10-16        View(s) : 89

Oil casing is critical for shale oil and gas horizontal wells, where long wellbores, complex stress, and repeated high-pressure hydraulic fracturing create demanding service conditions. Casing supports the wellbore, isolates formations, maintains pressure integrity, and provides a structur...

oil well casing  P110 and Q125 oil well casing

How to choose between P110 and Q125 oil well casing? Application scenarios for high-strength casing.

Keywords :oil well casing P110 and Q125 oil well casing        Update : 2026-10-15        View(s) : 84

P110 and Q125 are high-strength oil well casing grades under API Specification 5CT, with minimum yield strengths of 110,000 psi (≈758 MPa) and 125,000 psi (≈862 MPa). P110 is commonly used in deep wells where conventional grades lack sufficient strength, while Q125 may be justified when h...
