Abstract

A carbon steel for use in high pressure hydrogen service is provided. This steel may have greater than 1.20% manganese and greater than 0.035% sulfur. This steel may have no more than 0.16% carbon, no more than 1.10% manganese, no more than 0.010% phosphorus, no more than 0.05% sulfur, no more than 0.02% silicon, no more than 0.15% copper, no more than 0.10% nickel, no more than 0.1% chromium, no more than 0.03% molybdnium, no more than 0.40% aluminum, no more than 0.02% vanadium, no more than 0.0005% boron, no more than 0.003% titanium, and no more than 0.02% niobium.

Claims

1. A hydrogen wellhead completion method, comprising inserting a casing string into a well borehole in hydrogen service, and cementing the casing string at a surface, wherein to mitigate hydrogen embrittlement the casing string is fabricated from two or more casings fabricated from two or more seamless pipes or a seamless casings of carbon steel comprising greater than 1.20% manganese, a maximum of 0.16% carbon, a maximum of 0.010% phosphorous, a maximum of 0.02% silicon, and greater than 0.035% sulfur, wherein the two or more seamless pipes or a seamless casings are welded together.

2. A wellhead completion method, comprising inserting a casing string into a well borehole in hydrogen service, the casing string penetrating cap rock and salt mass, and cementing the casing string with gas blocking cement, wherein to mitigate hydrogen embrittlement the casing string is fabricated from two or more casings fabricated from two or more seamless pipes or a seamless casings of carbon steel comprising greater than 1.20% manganese, a maximum of 0.16% carbon, a maximum of 0.010% phosphorous, a maximum of 0.02% silicon, and greater than 0.035% sulfur, wherein the two or more seamless pipes or a seamless casings are welded together.

3. A wellhead completion method, comprising inserting a casing string into a well borehole that penetrates a salt mass, and cementing casing string with salt saturated cement, wherein to mitigate hydrogen embrittlement the casing string is fabricated from two or more casings fabricated from two or more seamless pipes or a seamless casings of carbon steel comprising greater than 1.20% , a maximum of 0.16% carbon, a maximum of 0.010% phosphorous, a maximum of 0.02% silicon, and greater than 0.035% sulfur, wherein the two or more seamless pipes or a seamless casings are welded together.
