H2S Standards
Minimum standard and general practices for carrying out operations in presence of H2S.
1. In general for oil and gas tubular selection, a sour environment is defined if H2S partial pressure > 0.05 psi and is H2S found on a:
a. Low pressure gas well (P < 5 bar)
b. Low pressure oil wells (< 15 bar) and low GOR (< 80 m3/m3) oil wells.
2. It is the responsibility of the subsurface department to identify and define the possibility to encounter sour gas . . .
