Preliminary analysis of Adani Wellspun Corporation Limited (AWEL), a joint venture company between between Adani Group (65% shareholding) and Welspun Enterprises Limited (35% shareholding), gas discovery in Mumbai Offshore‘s Tapti-Daman Sector block indicate that it has a high potential of commerciality with Gas Initially Inplace Place (GIIP) Contingent resources (2C) to the tune of 514 billion cubic feet (BCF) with additional Prospective resources of 50 BCF. 

Additionally, seismic inversion, conventional core and PVT studies of data collected from the discovery well are being analysed to assess the full potential of the find; preliminary results indicate potential upsides to estimated resources. 

The Format - B has been uploaded on Directorate General of Hydrocarbons (DGH) portal by AWEL which states that gas discovery made and announced earlier has got potential commercial interest. The drilling of an exploratory well in the NELP-VII area (MB-OSN-2005/2) in March 2021 has struck substantial quantities of gas and condensate at three reservoir levels. The pay zones and flow rates encountered have exceeded AWEL’s initial estimates. 

Out of the three potential zones identified, two objects were tested by Drill Stem Testing (DST), flowing substantial gas and condensate to the surface. 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“ 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“ choke with a FTHP of 2566 psi.
