## MINISTER OF STATE (I/C) IN THE MINISTRY OF PETROLEUM & NATURAL GAS (SHRI DHARMENDRA PRADHAN)

(a)  During last three years, crude oil & natural gas production, reserves accretion and  exploration and production expenditure made by Oil & Natural Gas Corporation (ONGC) Limited; Oil India Limited (OIL) and Private/JV companies are at Annexure-I, II and III respectively .

(b)  The  details  of  survey  conducted/proposed  to  be  conducted  by  ONGC,  OIL  and  Private/JV  companies  are  at Annexure-IV,  V  and  VI respectively .

(c) Government has approved Hydrocarbon and Exploration Licensing Policy (HELP) coupled with Open Acreage Licensing Policy and same has been notified on 30 th March 2016.  This policy provides for a uniform licensing system to explore and produce all hydrocarbons such as oil, gas, coal bed methane, shale oil/gas, etc. under a single licensing framework. Policy also provides many incentives such as reduced royalty rates for offshore  blocks,  marketing  &  pricing  freedom  and  easy  to  administer  revenue  sharing  model.  On  completion  of  preparatory  work  by  DGH, exploration blocks under HELP is likely to be offered.

(d)  The  share  of  ONGC in Balance Hydrocarbon reserves is about 52.7% of total hydrocarbon reserves of 1888 Million Metric Tonne of Oil Equivalent (MMToe).  During 2015-16, crude oil production by ONGC is about 22.368 Million Metric Tonne(MMT), which is 60.5% of the total crude oil production in the country . The share of ONGC in natural gas production is about 65.6% of the domestic natural gas production of 32.249 Billion Cubic Meter (BCM). The reserve to production (R/P) ratio for oil and gas in the country is about 17.6 years and 45 years respectively as per BP Statistics-2015. Globally, R/P ratio for crude oil is ranging from 2.8 to 89 years while R/P ratio in case of natural gas varies from 5.7 to 78.2 years (Source BP-Statistics).

(e) Indian Oil Corporation Limited (IOCL) has been awarded 21 exploration blocks (Two Block as Operator, 19 Blocks as Non-Operator). All these blocks are at exploration stage and no crude oil & natural gas production has commenced till date. (f)  As  per  the  Crude  Oil  Sales  Agreement  (COSA)  entered  into  between  the  PSU  upstream  companies  and  refineries/OMCs,  the  price  of indigenous crude is benchmarked to the international market price of equivalent crude oil.
