Cairn Oil & Gas has partnered with Electromagnetic Geoservices (EMGS) to perform a 3D Controlled Source Electro-magnetic (CSEM) survey in the deep-water Krishna-Godavari (KG) Basin off India’s east coast.
CSEM is a geophysical approach used for subsurface models that improves the accuracy of hydrocarbon detection and reduces exploration risks.
The survey, currently under way at the /1 block using the Atlantic Guardian vessel, utilises EMGS’ Deep Blue source system.
Over the coming weeks, data acquisition will continue, with subsequent processing set to deliver more precise insights into the deep-water block’s potential.
By integrating the new CSEM data with recently reprocessed 3D seismic data, Cairn aims to better characterise and prioritise its offshore exploration prospects within the block.
Cairn Oil & Gas chief exploration officer Sam Algar said: “The acquired data will support definition of locations for exploration, appraisal and subsequent development, ensuring drilling decisions are based on the most accurate and comprehensive subsurface data.
“By leveraging the global expertise from EMGS and the latest advancements in CSEM technology, the /1 block is poised for successful exploration and development, unlocking its hydrocarbon potential.”
Cairn’s KG basin assets span more than 4,500km² in water depths of between 500m and 2,500m. Drilling is due to commence in 2026 across a 3,600km² area that includes four gas discoveries and numerous prospects with multi-trillion cubic feet potential.
Cairn Oil & Gas chief financial officer Hitesh Vaid said: “Cairn has been at the forefront of technology adoption for efficient exploration and production in India’s upstream sector. Through our partnership with EMGS, we will fast track development of the deep-water block in line with our vision to contribute 50% of India’s oil and gas production.”
Recently, Cairn formed an alliance with TechnipFMC to leverage the latter’s engineering, procurement, construction and installation model to fast-track the development of subsea infrastructure for deep-water projects in India.
