Offshore seismic surveys India
Offshore seismic surveys in India are integral to the country's oil and gas exploration activities, helping identify potential hydrocarbon reserves beneath the seabed. Conducted mainly in the Krishna-Godavari (KG), Cauvery, Mahanadi, Mumbai Offshore, and Andaman basins, these surveys use advanced 2D, 3D, and 4D seismic technologies. The Directorate General of Hydrocarbons (DGH) and major upstream companies like ONGC, Oil India Limited (OIL), and private players such as Reliance Industries and Cairn Oil & Gas are active in conducting offshore seismic studies to support India's energy security Under the Open Acreage Licensing Policy (OALP) and Hydrocarbon Exploration and Licensing Policy (HELP), the Indian government has promoted exploration in unexplored offshore areas. Seismic acquisition under the National Seismic Programme (NSP) has significantly improved subsurface imaging, enabling accurate resource assessments. Multiclient seismic data is also being encouraged to attract foreign investment and improve basin understanding. Environmental clearances and regulatory approvals are mandatory before offshore seismic activities commence, ensuring minimal ecological impact. The surveys involve airgun arrays, hydrophones, and streamer cables to capture reflected sound waves, processed using high-resolution software to map geological formations. The growing demand for oil and gas, combined with deepwater exploration opportunities, continues to boost India’s offshore seismic survey sector. New tenders and data licensing rounds are regularly floated by DGH, attracting both Indian and global geophysical service providers. Offshore seismic surveys are crucial for boosting domestic production, reducing import dependency, and enhancing India’s self-reliance in energy exploration, Offshore Seismic Surveys, Seismic Exploration, Oil And Gas India, Hydrocarbon Exploration, DGH India, Offshore seismic surveys India, Indianpetroplus
