Industrial operations in high H2S gas wells can cause serious environmental, financial & health consequences. Risk management is important, especially when the world is at war with the SARS-COV-2 pandemic; we should have stronger boundaries to protect lives. One of the common methods is the hierarchy method. In this study, by combining this method and designing a new correlation to calculate static bottom hole pressure at gas wells, we tried to have strong risk management with the final goal of replacing the industrial operation. In the past, time-consuming and imprecise trial and error methods& expensive operations were used to calculate static bottom-hole pressure for gas wells. So, a general equation was modified based on field observations to obtain more accurate static bottom-hole pressure predictions. For this purpose, a unique adjustable parameter, based on the history matching of wells, has been proposed for each reservoir. The accuracy of this equation was investigated in three Iranian gas reservoir information. Good agreement was obtained between the field observations and this proposed equation. The precision of this method depends on field data, and with increasing numbers of field tests, the model becomes more accurate.
