Summary

* An accessible resource, covering the fundamentals of carbonate reservoir engineering * Includes discussions on how, where and why carbonate are formed, plus reviews of basic sedimentological and stratigraphic principles to explain carbonate platform characteristics and stratigraphic relationships * Offers a new, genetic classification of carbonate porosity that is especially useful in predicting spatial distribution of pore networks. * Includes a solution manual
