Abstract

Geological Process Modelling (GPM) is a quantitative tool to forward model depositional and stratigraphic processes of erosion, transport and deposition of clastic sediments and carbonate growth and redistribution on a grain size scale while honouring physics-based flow dynamics. Using the rock physics properties, synthetic seismic volume is generated, which allow analysis of stratigraphic features and their seismic expression on different scale. The well and seismic consistent forward stratigraphic model can provide new insights into the characteristics of sub-surface reservoirs over conventional geological models. GPM Modelling was carried out in the south of Mumbai High area for both clastic i.e., Panna Formation and carbonate i.e., Devgarh and Bassein formations wedging out against the Basement around Bombay High. In Panna Formation, Source provenances were defined and distribution of sand through time and space was determined by combination of different processes such as diffusion (weathering and gradient based transport), steady flow (Channel transport), sea wave, and carbonate growth.
