Neotectonism and Its Effect on Gas Migrating Features in Offshore KG Basin India

Summary KG basin is a proven petroliferous basin where frequent exploration and drilling activities are carried out. In the present study, we have used industry derived 3D seismic volume and well logs to obtain inverted 3D seismic impedance and Vp/Vs cubes, which are used to identify potential hydrocarbon zones and gas migrating features in the KG basin. An attempt has also been made to understand neotectonism and its effect on the fluid migration which eventually weaken the compressibility of basin sediments, producing a potential weak zones, escalating the slumping/sliding of basin sediments, affecting the stability of basin slope and posing concern on future geohazards.
