Patent ID: 8812334

Claim:
A method for performing oilfield operations for an oilfield having a subterranean formation with an underground reservoir therein, the oilfield being provided with at least one wellsite with oilfield equipment for extracting fluid from the underground reservoir, comprising: collecting, by a geoscience application, data comprising trajectory and earth properties associated with a planned well for the geoscience application to obtain a geoscience model, wherein the geoscience application is geoscience modeling software; invoking, in the geoscience application, a well planning system integrated with the geoscience application, wherein the well planning system is a plugin to the geoscience application; extracting, by the well planning system, the trajectory and the earth properties from the geoscience model to obtain an extracted trajectory and extracted earth properties; calculating, by a computer processor executing the well planning system, a plurality of individual risk indexes for a plurality of individual risks using the extracted trajectory and the extracted earth properties; calculating, by the well planning system and using the plurality of individual risk indexes, a plurality of ranked risk category values for a plurality of ranked risk categories and a ranked subcategory risk index for a ranked subcategory risk, wherein said plurality of ranked risk categories comprises an average individual risk, a subcategory risk further calculated using the ranked subcategory risk index, an average subcategory risk further calculated using the ranked subcategory risk index, a total risk, an average total risk, a potential risk for each design task, and an actual risk for each design task; and displaying, in the geoscience application, the plurality of ranked risk category values within a geological context of the geoscience application, wherein displaying the plurality of ranked risk category values comprises displaying a visualization of the total risk versus the actual risk for each design task.
