Onshore and offshore drilling oil and gas wells have been known as one of the most hazardous industries. In this sector, unsafe behaviors, actions and operational decisions could have irreparable consequences. Therefore, promoting safety culture in organizations can lead to the prevention of accidents and catastrophes. Soft Operational Research (O.R.) techniques such as Soft Systems Methodology (SSM) and Strategic Options Development Analysis (SODA) can be utilized for providing awareness for practitioners to know their complex problems better. Moreover, these techniques can aim researchers to find a proper solution for those complicated problem. In this paper, identification and analysis of factors influencing the safety culture in the drilling industry are done by strategic options development and analysis (SODA) methodology in order to prevent and reduce accidents which are the results of unsafe actions and behaviors.
