Adani Welspun Exploration Limited (AWEL) said that the gas discovery it announced in March 2021 offshore Mumbai has been found to have potential commercial interest.

The company, which is a 65:35 joint venture between Adani Group and Welspun Enterprises, had found gas in the Tapti-Daman Sector of the Mumbai offshore basin by drilling an exploration well in the MB-OSN-2005/2 block.

According to Adani Welspun Exploration, preliminary analysis of the data suggest that the block has a high potential of commerciality with gas initially in place (GIIP) contingent resources (2C) of 514 billion cubic feet (BCF) with 50 BCF in additional prospective resources.

Apart from that, seismic inversion, conventional core, and pressure volume temperature (PVT) studies of data gathered from the discovery well are being studied to evaluate the full potential of the find, said Adani Welspun Exploration.

The company said that pay zones and flow rates intersected by the well had surpassed its initial estimates. A couple of objects from the three identified potential zones that were tested by drill stem testing (DST), flowed significant volumes of gas and condensate to surface.

Adani Welspun Exploration stated: “Object -I (3m) a clean sandstone reservoir flowed 9.7 million standard cubic feet per day (mmscfd) of gas along with 378 barrels /day of condensate through a 28/64 inch choke with a flowing tubing head pressure (FTHP) of 2659 psi.

“Object -II (15m) another thick clean sandstone reservoir flowed 9.1 mmscfd of gas along with 443 barrels /day of condensate through a 28/64 inch choke with a FTHP of 2566 psi.”
