Cairn Oil & Gas, a part of the Vedanta Group, has partnered with Norwegian marine electromagnetic specialist Electromagnetic Geoservices (EMGS) to conduct a 3D Controlled Source Electromagnetic (CSEM) survey in its deepwater Krishna-Godavari (KG) block, located off India’s East Coast.
Cutting-Edge Technology for Subsurface Mapping
CSEM technology plays a vital role in modern exploration by mapping subsurface resistivity, which enhances the accuracy of hydrocarbon detection. Cairn is among the early adopters of 3D CSEM in India, reflecting its commitment to incorporating advanced geophysical tools for reducing exploration risks.
EMGS, recognized as a global leader in marine electromagnetic surveys, has supported top energy supermajors worldwide and now brings its expertise to Cairn’s offshore campaign.
Survey Operations Underway with “Deep Blue” Source
Currently, the EMGS vessel, Atlantic Guardian, is collecting data from the KGDWHP-2017/1 block using its sophisticated “Deep Blue” source system. Data acquisition will continue over the coming weeks, after which EMGS will process the survey to deliver high-resolution insights into the block’s geological structures.
Integrated Approach to Risk Reduction
The survey’s goal is to improve subsurface model accuracy and significantly reduce uncertainty by integrating CSEM data with Cairn’s recently re-processed 3D seismic data. This integration will offer a more detailed understanding of the subsurface and aid in identifying optimal drilling locations.
“Through our partnership with EMGS, we will fast-track development of the deepwater block,” said Hitesh Vaid, Chief Financial Officer, Cairn Oil & Gas. “This aligns with our vision to contribute 50% of India’s oil and gas production.”
Poised for Drilling and Future Development
Sam Algar, Chief Exploration Officer at Cairn, said, “The acquired data will help define locations for exploration and appraisal. It will also guide development, ensuring drilling decisions rely on the most accurate and comprehensive subsurface data.”
The KGDWHP-2017/1 block spans over 4,500 sq km. It features water depths ranging from 500 to 2,500 meters and holds four gas discoveries. Cairn aims to begin drilling in 2026 across a 3,600 sq km area with multi-TCF potential.
Expanding Strategic Partnerships
The move follows Cairn’s March 2025 strategic alliance with a global subsea technology leader. The partnership aims to accelerate the deployment of integrated infrastructure for deepwater exploration in India.
As reported by thehindubusinessline.com, Cairn is leveraging global expertise, innovative technologies, and strategic partnerships. This approach is rapidly advancing its vision to unlock the full potential of India’s offshore energy reserves.
