Fuzzy consequence modeling of blowouts in Iranian drilling operations; HSE consideration

摘要

The main objectives of any drilling companies are drilling safely, providing usable well completion and minimizing costs. Among all, health, safety and environment (HSE) consideration supersedes. Also, oil and gas well-drilling industry is an industry with high level of risks concerning HSE. Not only does each factor of these risks need to be analyzed but also need to be adjusted by the appropriate risk modeling. This project is assigned to model risk and consequence assessment for some aspects of blowout. The consequences should be formulated but require some adjustment. Proper Delphi group for risk assessment is made to localized risk factors. As there is uncertainty during data collection, the fuzzy approach is used. Finally, prioritizing the assets according to their criticality demonstrate significance of the risk.
