## MINISTER OF PETROLEUM & NATURAL GAS (SHRI DHARAMENDRA PRADHAN)

(a) & (b). The production from an oil well depends on various factors such as reservoir profile, location, geological conditions etc. Over a period of time, the production from a well  declines  due  to  multiple  reasons  including  aging/maturing  of  the  well.  In  India, most of the production under nomination regime is from matured/aged fields/wells. In mature fields production declines over a period of time and subsequent revival of

these wells is a continuous and dynamic process and is an intrinsic characteristic of any oil field.  Exploration & Production (E&P) companies make efforts to revive such wells  by  using  techniques  such  as  periodical  well  intervention,  workover  jobs,  well simulation jobs including hydro-fracturing, installation of suitable artificial lift systems and side-tracking of wells etc.

(c)  &  (d). Government,  inter-alia,  has  taken  following  Policy  initiatives  to  enhance domestic production of oil and gas, including in the state of Gujarat:-

- i.  Policy  for  Relaxations,  Extensions  and  clarifications  under  Production  Sharing Contract (PSC) regime for early monetization of hydrocarbon Discoveries, 2014.
- ii.  Policy on Testing Requirements, 2015.
- iii.  Discovered Small Field Policy, 2015.
- iv.  Hydrocarbon Exploration and Licensing Policy, 2016.
- v.  Policy for Extension of Production Sharing Contracts, 2016.
- vi.  Setting up of National Data Repository, 2017.
- vii.  Appraisal of Unappraised area in Sedimentary Basin.
- viii.  Re-assessment of Hydrocarbon Resources.
- ix.  Policy for early monetization of Coal Bed Methane (CBM)

(e). ONGC has explored 286.68 MMT of In-Place Volumes and 65.95 MMT of Ultimate Reserves  of  Oil  during  the  last  three  years  i.e.,  2014-15,  2015-16  and  2016-17. Basin/State/UT-wise  details  of  reserves  accretion  made  by  ONGC  during  last  three years 2014-15, 2015-16 and 2016-17 are given in Annexure.

(f). As  on  01.04.2017,  ONGC  has  established  1549.44  MMT  of  oil  reserves  since inception, and 568.89 MMT of oil reserves are available for production. The details of ONGC's standalone crude oil (including condensate) production for last three years i.e. from 2014-15 to 2016-17 is given below.

| Year                          |   2014-15 |   2015-16 |   2016-17 |
