Annexure X: Details of oil & gas resource conversion in NER<br />
Details of oil & gas resource conversion by ONGC in northeast<br />
As a result of its exploratory efforts as on 01.04.15, ONGC has made 76 hydrocarbon discoveries<br />
which include 55 discoveries in Assam, 17 in Tripura, 3 in Nagaland and one in Mizoram. This has<br />
resulted in the establishment of 904.32 MMt (O+OEG) in place and 269.21MMt (O+OEG) ultimate<br />
reserves in Assam & Assam Arakan Basin. The state-wise distribution of established, in-place and<br />
ultimate volumes is tabled below.<br />

Targets by ONGC for increase in in-place reserves<br />
a. Assam shelf: In-place accretion realisation from 782.6 MMt to 952.6 MMt by <strong>2030</strong> and in terms<br />
of prognosticated resource conversion from 65 % to 80%<br />
b. Fold belt sector covering Cachar, Tripura, and Mizoram: In-place accretion realisation from<br />
101.95 MMt to 167.95 MMt by <strong>2030</strong> and in terms of prognosticated resource conversion from<br />
17 % to 28%<br />
Initiatives by ONGC:<br />
Induction of a new rig to achieve exploratory drilling levels of 28 wells by 2016-17 from the current<br />
level of16 wells<br />
Details of oil & gas resources in YTF areas of NER for Oil India<br />
2P and 1P reserves of Oil India as on 01.04.2015 are tabled below.<br />

Gas (BCM) 44.10 23.79<br />
O+OEG ( MMTOE) 121.31 51.76<br />
Total prognosticated reserves estimated by Oil India from YTF areas are 1,834 MMTOE. Considering<br />
the same conversion percentage as calculated above for conversion of prognosticated to established<br />
and established to recoverable category for reserves in NER, the estimated established and<br />
recoverable reserves from YTF areas for Oil India are as such.<br />
State Established (MMTOE) Recoverable (MMTOE)<br />
