Speaker:  Sagnik Dasgupta, Schlumberger

Source rocks are generally low porosity, permeability and very complex in mineralogy.  The complex mineralogy of these source rocks is attributed to depositional setting and influence of both clastic and carbonate environments in highly alternating sequences of these stratigraphy. Development of such complex rocks requires detailed understanding for various elements. While seismic data provide spatial and vertical description of the elastic properties for these reservoirs, rock physics based lithological classification provides information about the description of reservoir properties and understanding for its complexities.  Identification and definition of rock type or elastic facies are crucial, as it help to break down the mineralogical complexities into relatively simple units. Rock physics analysis of different minerals and their effect of elastic properties determines the major load bearing elements within a complex sequence. This process helps to build different rock physics models suitable for these different units. Bayesian inverse problem formulation is used to estimate lithology description from seismic inversion.  This process not only provides description of maximum aposteriori estimate facies but also provide associated probabilities for the facies and other facies. The spatial distribution of these probabilities provides detailed knowledge of the variability of these different lithofacies before drilling and reduce uncertainty in well placement and horizontal well trajectories. It also provides information about fracture containment by adjacent competent units.
