Abstract

The tectonic history of the Mumbai Offshore Basin from the time of Madagascar separation to the present day has shaped the structural configuration, sedimentation pattern, as well as migration and entrapment of hydrocarbons in the Basin. This paper analyses the imprint of the tectonic history through faults mapped on latest 3D seismic data spanning 13 volumes covering 32,000 sq.km. The faults have been categorized into four types according to their genesis and timing of evolution. Subsequent to that, the study integrates oil to source data with the mapped fault trends to establish most likely play fairways and finally, it analyses the hydrocarbon accumulation trends to identify probable dry and wet corridors.
