Earth models for underground resource exploration and estimation

Abstract : This chapter introduces a certain number of geological concepts that are reused in the rest of the book. It depicts the geological objects classically explored for underground resources exploitation (hydrocarbon, water, storage of energy or wastes) such as sedimentary basins, aquifers or reservoirs. Aim and use of geological modeling are presented. Some of the input data and some characteristics of geological models such as components and versioning are described.
