EXPLORATION OF OIL AND NATURAL GAS DEPOSITS
(a) The Directorate General of Hydrocarbons (DGH) conducts various geo-scientific surveys in onland
and offshore areas of the country to ascertain the hydrocarbon prospectivity. The details of such
surveys carried out by DGH in the last three years and the current year ( till January,2013) are
given as under:

In addition to the above surveys, Oil and Natural Gas Corporation Ltd. (ONGC), Oil India Ltd.
(OIL) and Private/JV companies also carry out various geo-scientific surveys in the awarded
blocks under the Production Sharing Contract (PSC) regime in line with the Work Programmes in
the PSCs. During the last three years and current year (till January, 2013), exploration
activities in terms of acquisition of 1,08,454 Line Kilo Meter (LKM) of 2D and 1,02,901 Sq. KM
(SKM) of 3D seismic surveys and drilling of 243 exploratory wells have been carried out in 172
exploration blocks/fields, resulting in 52 hydrocarbon discoveries ( 31 oil and 21 gas) . Out of
these, the Declaration of Commerciality (DoC) of 7 oil discoveries made in Gujarat has been
reviewed by the Management Committee (MC) and an In-Place oil volumes of 64.85 Million Barrels
has been established. The other discoveries are under various stages of evaluation/appraisal/
commerciality. The details of block-wise, year-wise and area-wise exploration activities and
discoveries made are given in Annex-I & Annex-II respectively.
In the exploration blocks awarded under nomination regime, ONGC and OIL are carrying out
exploration for hydrocarbons in the Country. ONGC has carried out 1401.2 LKM of 2D seismic
survey and 3462.54 SKM of 3D seismic survey as well as drilled 96 exploratory wells during
last 3 years and current year in 59 blocks. The state-wise and block-wise details of exploration
work carried out by ONGC are at Annex-III. OIL has carried out 2462.31 LKM of 2D seismic survey
and 1258.18 SKM of 3D seismic survey as well as drilled 25 exploratory wells during last 3 years
and current year. The state-wise and block-wise details of Exploration work carried out by OIL are
at Annex-IV. As a result of these exploratory efforts carried out in nomination blocks, ONGC and
OIL have made 19 and 25 hydrocarbon discoveries respectively.
(b) & (c) Exploration works are being carried out as per the industry standards and provisions of
Production Sharing Contracts (PSCs) in the country including the state of Rajasthan.
(d) & (e) Both Public sector companies as well as Private Indian and Foreign Companies are
carrying out hydrocarbon exploration as per the provisions of PSCs, as per details in Annex-I
to IV.
