RESUMO

Correspondence analysis is an exploratory tool for the analyses of large data matrices. Its application results iR simultaneous graphical displays of objects and variables of da:ta matrices on the same coordinate plane, providing easy interpretation of the relations among them. The great advantage of graphical representation of a data matrix is to provide easier interpretation rather than numerical descriptions. Besides, it is a good method to summarize, simplify and allow global understanding of matrix information. Correspondence analysis is more suitable for discrete variables, but it can be applied to continuous variables as well, after adequate transformations. This technique was applied to a set of data comprising macroscopic core description of a sequence of carbonate rocks from Lagoa Feia Formation, Campos basin. From the results of this analysis, it was possible to identify groups of wells having similar behavior with respect to several variables and to map the geographic distribution of those groups
