... ( Stamatelatos, 2000 ). Figure 3 shows the workflow of the probabilistic risk assessment (PRA) in the optimization of CO 2 injection well locations, bringing the general principles to the specific engineering study area. Risk comes from uncertainty and "The uncertainty is usually expressed as a probability...

... at core and well-log scales, then upscaled to the model zone scale. The EOD interpretations are laterally extended using lithology (sandstone, shale and igneous rock) probability maps derived from quantitative seismic interpretation (QSI). Multiple EOD scenarios are generated to capture the possible range...

... Abstract Major accident is one of the risks that oil and gas industries are exposed to. Although its probability of occurrence is low, the impact of this unfortunate event could result in significant losses in terms of personal safety, environment preservation, company asset, production...
