Norwegian Seismic Service Provider EMGS to Conduct 3D CSEM Survey for Cairn Oil & Gas

Norwegian seismic service provider Electromagnetic Geoservices (EMGS) has been hired by India’s Cairn Oil & Gas to conduct a 3D controlled source electromagnetic survey for its exploration campaign in the deepwater Krishna-Godavari block on India’s east coast.

Cairn will be one of the first companies in India to utilise 3D CSEM survey technology, which is known for mapping subsurface resistivity.

The survey will be conducted using EMGS’ vessel, Atlantic Guardian. The vessel is expected to acquire data in the block over the next few weeks. Once data acquisition is complete, the survey will be processed to enable enhanced exploration strategies.

The data gathered will be integrated with re-processed 3D seismic data, facilitating the creation of more accurate subsurface models. This integration is expected to significantly reduce exploration risks and help in identifying and prioritising key prospects within the block’s extensive offshore exploration portfolio.

Cairn Oil & Gas currently holds over 4,500 sq km of offshore deepwater blocks in the KG Basin, with water depths ranging from 500 to 2,500 m.

The company plans to begin drilling operations in 2026 within a 3,600 sq km area that includes four significant gas discoveries with a multi-trillion cubic feet potential.
