Cairn Oil & Gas said on Friday it has partnered with Norwegian Electromagnetic Field (EMG) to obtain a 3D controlled source electromagnetic (CSEM) survey for its exploration campaign at the Deepwater Krishna-Godavari block on the east coast.
CSEM is a geophysical method used to map underground resistivity, increasing the accuracy of hydrocarbon detection. EMGS is the leader in the global marine electromagnetic market, collecting data from global Supermajor around the world. Cairn is one of the early adopters of India’s 3D CSEM research technology, said Vedanta Group Firm.
Currently, the EMGS ship, Atlantic Guardian, is using an advanced “Deep Blue” source system to retrieve data for the KGDWHP-2017/1 block. He added that he will continue to retrieve data within the block over the coming weeks, then process the data to provide much more accurate findings of deep-sea blocks.
The purpose of this study is to increase the accuracy of the underground model and reduce search risk by integrating the collected CSEM data with recently reprocessed 3D seismic data.
Hitesh Vaid, Chief Financial Officer of Cairn Oil & Gas, said “We will rapidly track the development of the Deepwater block in line with our vision to contribute 50% of India’s oil and gas production through our partnership with EMGS.”
“The data obtained support the definition of locations for exploration, assessment, and subsequent development, ensuring that excavation decisions are based on the most accurate and comprehensive underground data.”
By leveraging global expertise from EMGS and the latest advancements in CSEM technology, the KGDWHP-2017/1 block is poised to unlock the potential of hydrocarbons for successful exploration and development.
In the beginning of March 2025, Cairn formed a strategic alliance with global technology leaders to accelerate the delivery of integrated undersea infrastructure for India’s deepwater projects.
The Cairn features 4,500 square kilometres offshore deep sea blocks of the KG Basin, with water depths ranging from 500 to 2,500 meters. The company plans to begin drilling in 2026 in a 3,600 square km area with four gas discoveries and a large number of prospects.
