drilling industry provides a significant potential for occupational health risks. thus, health-related hazards (chemical, physical, ergonomic and biological) must be recognized, evaluated and controlled in order to prevent occupational illnesses which come from exposure to them. for these, a good occupational health risk assessment needs to be applied. risk assessment monitors risks and provide...

drilling operations are exposed to a variety of hazards, some of which may be location and activity dependent and each could pose different risk from different paths.  drilling operation may be vulnerable to hurricanes in one region and be exposed to geohazards in another. however, there are other hazards, (e.g. corrosion, age degradation, poor maintenance), which equally affects every rig. ide...

Abstract This paper establishes the risk assessment index system according to characteristics of oil and gas drilling engineering cooperation project. After modularizing risk indexes of oil and gas drilling engineering cooperation project into eight clusters, risks are evaluated on the basis of multi-level fuzzy comprehensive evaluation method. The study is to construct risk assessment indexes ...

Drilling engineering comprises a major part of production and exploration in oil fields and drilling risk is a significant ingredient to success. As one of the crucial ways to terminate oil spill event, relief well assumes great responsibility. Thus it is essential to analyze and assess the risk of relief well technique before drilling operation in order to guarantee rescue project work smoothl...

Oil and gas drilling is based, increasingly, on operational technology, whose cybersecurity is complicated by several challenges. We propose a graphical model for cybersecurity risk assessment based on Adversarial Risk Analysis to face those challenges. We also provide an example of the model in the context of an offshore drilling rig. The proposed model provides a more formal and comprehensive...

In order to achieve the offshore petroleum industries "zero harm" goal to the environment, the environmental impact factor for drilling discharges was developed as a tool to identify and quantify the environmental risks associated with disposal of drilling discharges to the marine environment. As an initial step in this work the main categories of substances associated with drilling discharges ...

Drilling engineering is not only a systematic engineering that involves several workcategories, work procedures,intersectant and continuous operation, but also is a concealed underground engineering. There are uncertain factors in drilling projects, which have the characteristics of high investment and risk. On the basis of the overall analysis of the two factors of geology and engineering, the...
