## MINISTER OF STATE IN THE MINISTRY OF PETROLEUM AND NATURAL GAS (SHRI SURESH GOPI)

(a)  to  (c):  The  Government  had  conducted  the  Hydrocarbon  Resource  Assessment  Study (HRAS), 2017 to evaluate the hydrocarbon potential of various sedimentary basins, including the  sedimentary  basins  of  Mumbai  Offshore,  Saurashtra  and  Cambay  encompassing  the Union Territory  of  Daman  and  Diu  and  its  surrounding  areas.  The  offshore  area  adjoining Daman and Diu forms part of the Mumbai Offshore Basin and Saurashtra Basin with Cambay Basin in close proximity. The estimated in place Hydrocarbon potential as per HRAS 2017 is as follows:

| Basin           | Estimated In place (Million Metric Tonnes of Oil Equivalent)   |
|-----------------|----------------------------------------------------------------|
| Mumbai Offshore | 9,646                                                          |
| Saurashtra      | 1,325                                                          |
| Cambay          | 2,586                                                          |

The Government has adopted a holistic and basin-level approach for hydrocarbon exploration and  infrastructure  development  under  policies  such  as  the  Hydrocarbon  Exploration  and Licensing  Policy  (HELP)  and  the  Open  Acreage  Licensing  Programme  (OALP).  The Government  has  been  promoting  integration  of  regional  economies  with  petroleum  and natural gas infrastructure through the expansion of pipelines, LNG terminals, refineries, and downstream facilities in the country, including along the coasts of Gujarat and Maharashtra. While no standalone  roadmap has  been prepared exclusively for Daman and Diu, ongoing continuous process of expansion of oil and gas infrastructure in the western coastal region is expected  to  support  industrial  activity,  employment  generation,  and  availability  of  cleaner fuels for industries located in the region.
