Abstract

Offshore basins located at Eastern continental margin of India has drawn considerable interest due to its major hydrocarbon potential. Sonic and density log data have been used to estimate pore pressure and overburden stresses for four deepwater wells. These wells located at water depths varying from 585 m to 1265 m, where, their penetrated vertical depth reaches up to 3960 m in clastic sediments. In order to compute effective in-situ horizontal stress magnitude, Poisson
