Exploration and Development of Oil and Gas
Exploration
Liberalization policies adopted in E&P sector and continuation of offer of exploration acreages under NELP and CBM through international competitive bidding process shall ensure exploration of about 1.245 million sq. kM of basinal area during the XI Plan period. By the end of XI Plan, exploration area offered will be about 80 percent of the total sedimentary basinal area and entire sedimentary basins may be opened up for exploration by 2015 as against the target of Hydrocarbon Vision by 2025.
Under the nomination regime, there was certainty of getting exploration blocks of choice but under NELP, exploration blocks are awarded based on quantitative bidding parameters such as work programme committed and Government’s take offered by the bidder. Consequently, availability of exploration acreages will have an element of uncertainty and accordingly exploration programme in terms of seismic surveys and drilling will only be indicative.
Exploration programme has been given as under:

Development Program
Oil discoveries made in Rajasthan by Cairn Energy India Pty Limited, gas discoveries in KG basin and other oil and gas discoveries made by NOCs will be undertaken during XI Plan. During XI Plan period ONGC and OIL have plans to implement IOR/EOR in the ageing fields, develop marginal and isolated fields and faster development of new discoveries made. The development wells to be drilled by ONGC, OIL and Private/JV companies during XI Plan are as under:

Crude oil production of 206.76 MMT during XI Plan period is about 23 percent higher than the X Plan likely achievement of 167.70 MMT. The increase in crude oil production will be mainly due to contribution by private company, Cairn Energy Pty Ltd., which will produce about 5-6 MMT per annum from Rajasthan.
Natural gas production during XI Plan will be about 224.56 BCM, which is about 41 percent increase as against likely natural gas production of about 158.79 BCM in X Plan period. This increase in gas production is mainly from K-G basin production of 40 MMSCMD by RIL. The gas production may further increase by development of GSPC discoveries and other RIL’s discoveries in KG basin.
Based on the envisaged inputs, it is estimated that overall reserve accretion during the X Plan in terms of oil plus oil equivalent of gas will exceed the production volumes during the same period, thus, resulting in Reserve Replacement Ratio (RRR) of more than unity.
E&P Strategies to Enhance Oil & Gas Production
Level playing field to public sector and private sector players including foreign players and provision of comparable incentives to all E&P companies.
Pursue extensive exploration in non-producing and frontier basins for knowledge building and new discoveries, including in deep-sea offshore areas.
Establishment of a ‘Knowledge Hub’ in India.
Strengthening of DGH and upstream oil and gas regulations.
Convergence of nomination regime into NELP Regime.
Faster development of oil and gas discoveries.
Development of isolated and marginal fields and creation of surface facilities.
Provide infrastructure status to E&P companies and competitive fiscal terms to attract significant investments in the sector.
Optimize recovery from ageing oil and gas fields.
Continue to offer more CBM exploration blocks.
100 percent speculative survey to carve out exploration blocks.
Efforts to get methane gas through in-situ gasification of coal.
Continuation of R&D efforts to exploit the potential of gas hydrates.
R&D efforts and feasibility to understand the potential of oil shale.
Availability of trained manpower and expertise in E&P sector.
Continue technology acquisition and absorption along with development of indigenous R&D and to ensure adequacy of finances for R&D required for building knowledge infrastructure.
Make E&P operations compatible with the environment and reduce discharges and emissions.
Continue to acquire acreages abroad for exploration as well as production.
