Abstract

3D Geocellular model (GCM) involves data integration through application of G&G concepts and experiences. Conceptual G & G models describe essential features of geological situations, explain the primary processes of the petroleum system, and provide important information about reservoir characteristics of the field under study. These conceptual models are being used as the key input for 3D reservoir Modeling. A fully integrated GCM consists of three stages: construction of structural model, designing facies & petrophysical model and volumetric estimation. These processes require integration of geological, geophysical, petrophysical, reservoir along with production data into a comprehensive model describing the physical features of the geologic system. Data driven model without proper G&G concept never completes as a realistic reservoir model, fails in predicting HC Inplace, recoverable reserve and production forecast with high degree of accuracy.
