Hydrocarbon Vision 2030 for North-East India was
released by MOPNG – GOI on 9th Feb 2016 at
Guwahati for developing North-East region as a
dominant Hydrocarbon Hub at the forefront of India’s
energy economy.
Hydrocarbon Vision 2030 for NER

37. 38
5 Pillars of North East Hydrocarbon Vision 2030
Production
Production enhancement contracts, technology
deployment and fast track clearances
•Develop service provider hubs
Projects
LPG, NG, POL Pipelines
•Refineries, Import links
•CNG Highways & 13 new CGD networks
Policy Moderate PSC, review resource pricing
•FacilitateVGF (Viability Gap Funding)
People
Clean fuel access for households
•Skill development
•Local community involvement
State government involvement in planning and
implementation
•Trade with SAARC countries
Partnership

38. 39
Developing North East Region as a dominant hub at forefront of India energy map
Hydrocarbon Vision 2030 for NER
1. Double the the production of Oil and Natural Gas (O + OEG in MMTOE)
2. Access of clean fuel (LPG/PNG) to 100% households in the region.
3. Bolster development through creation of service provider hubs.
4. Ensure availability to support growth in per capita Petroleum product consumption.
5. Provide pipe line connectivity by installing new POL & LPG pipe line.
6. Develop natural gas grid, CGD networks & CNG Highways.
7. Generate employment opportunities through industrial & skill development.
8. Promote manufacturing industry related to Oil & Gas in the region.
9. Incentivize production of Bio fuel in the region for providing access to clean fuels and
to boost rural economy.
10.Promote trade between North East Region of India & Neighbouring SAARC
countries.

Natural gas utilisation – Industry development
 Natural Gas as aVehicle Fuel
 PNG for Domestic Use (Piped Natural Gas) & CGD (City Gas
Distribution) network
 For production of Fertilizers.
 For heating in the leaching process for drying and curing processes
in Rubber Industry.
 For uniform heating during drying process of tea leaves in tea
processing industry .
 Natural gas can be used for powder drying, tiles drying and final
heat treatment.
