Integrated Geophysical and Geotechnical Study of a Southern Oil and Gas Field in Western Offshore, India

Abstract

The field under study is located toward the south of petroleum producing area of western Indian offshore. The field was initially partly developed and redevelopment has been started in recent years. During the initial and redevelopment phases, many geotechnical investigations and geophysical surveys have been performed. A collated data study of old and new geophysical and geotechnical data was done with the objective to establish the field wide identification of different soil strata and their engineering parameters. The engineering parameters established from this study will help to verify the reasonability of newly measured in situ and laboratory parameters. They can also be used to optimize the costly field and laboratory testing programmes. Moreover, this study will help in assessing soil conditions and assigning design parameters for upcoming geotechnical investigations where either data are inadequate or missing. In this paper, the results and conclusions inferred from the integrated study, shallow geologic and geotechnical conditions of the field are presented.
