Adani Welspun Exploration Ltd (AWEL), the 65:35 joint venture between the Adani and Welspun groups, will begin gas production from its block located in the prolific gas-prone Tapti-Daman sector of the Mumbai Offshore basin in 2028, a top executive at one of the parent companies said.

AWEL is also an operator with 100% interest in B-9 Cluster, an adjacent small field.

"The gas initially in place is 0.75 trillion cubic feet. We have submitted our plans to the Directorate General of Hydrocarbons and are awaiting approval. We hope to start production from the block from 2028," Welspun Enterprises managing director Sandeep Garg told ET in an interview.

The Adani Group holds 65% in AWEL through Adani Enterprises, while the Welspun Group owns 35% through Welspun Natural Resources - a wholly owned subsidiary of its flagship company, Welspun Enterprise. The companies have together invested around Rs 2,300 crore in the block so far.
