Natural Gas
Natural Gas Production (MMSCM)
Exploration and production of natural gas not only makes business sense but
it makes environmental sense as well due to its lower carbon profile. We thus
invest heavily in the exploration and production of natural gas. Natural Gas
production by ONGC during the year 2010-11 was 23,094.57 MMSCM which
was 101.4 % of the MoU target agreed with the Ministry of Petroleum and
Natural Gas and about half of the total gas production in India.

3. Unconventional Hydrocarbons
Underground Coal Gasification
Underground coal gasification converts coal to gas while still in the coal seam (in-situ). Gas is produced and extracted
through wells drilled into the unmined coal-seam by injection of oxidants, and bringing the product gas to the surface
through production wells drilled from the surface.
Building on our decades of drilling and natural gas production competency, we have ventured into the new frontier of
underground coal gasification and selected Vastan Mine block in Surat district, Gujarat for the Underground Coal
Gasification (UCG) Pilot project.
Coal Bed Methane
ONGC is currently operating in five Coal Bed Methane (CBM) blocks namely Jharia, Bokaro, North Karanpura and South
Karanpura Blocks in Jharkhand and Raniganj block in West Bengal.
To have a focussed approach for the development of CBM, a dedicated CBM development project is functioning from
Bokaro to comprehensively steer our CBM operations.
A collaborative research program with School of Petroleum Engineering (SCOPE), University of New South Wales
(UNSW), Australia for reservoir characterization, stimulation designing and stimulation studies is operational.
