Cairn Oil & Gas has successfully installed India's first-ever Sub-Sea Template (SST) on the west coast, within the Ambe block. This marks a significant breakthrough for offshore exploration as part of a Conductor Supported Platform installation.

Significance and Impact

This milestone represents a major advancement for marginal field monetisation in discovered small field blocks. The technology has the potential to reshape how smaller offshore discoveries are developed, making them economically viable and contributing to India's energy security. The installation work itself was notable as the first execution using a jack-up rig in the Indian offshore region.

Development Plans and Context

With the subsea structure now in place, the operator plans to initiate drilling operations soon to fast-track the development and monetisation of the oil and gas asset. The Ambe block, also known as CB-DSF-III, was awarded in 2021 as part of India's DSF bid round. The offshore asset is located in the Gulf of Cambay off Gujarat, covering approximately 728 square kilometres.

Broader Exploration Campaign

This project is part of a larger, ambitious exploration and investment programme. The company has initiated a bidding process to secure up to 12 rigs—10 onshore and two offshore—for a period of two to three years to execute multiple drilling programmes. The overall plan includes an investment of up to $5 billion over the next three years in exploration and development projects across India. This investment will target both conventional and unconventional hydrocarbons in:

• Deep and shallow waters off the east and west coasts.
• Onshore areas in Rajasthan and North East India.

The campaign aims to unlock hydrocarbons from Indian sedimentary basins, increase domestic production, and reduce the country's import dependency.
