Abstract:The latest development of information visual-ization technologies such as parallel coordinates,could be used in multivariate statistical analysis a-dopted for different domains of petroleum explora-tion and production. Benefitted from its well-foun-ded mathematical foundation about projective geo-metrical interpretation and duality properties,par-allel coordinates demystifies more than other waysabout the hidden trends and complex relationshipsamong different variants. After a brief introductionto reference model of information visualization andthe principle of parallel coordinates,we share thevisual mining process about how to apply parallelcoordinates to improve the understanding of rela-dons among geological risk factors.From novelrepresentation design to combination with classicalstatistic methods,this data mining process withthe help of parallel coordinates share heuristicthoughts with specialists about how to get deepunderstanding with visual data mining.
