With two exploration blocks covering parts of Wokha and Mokokchung and the state featuring in its Northeast investment plans, the company’s interest is growing – but concrete commitments for Nagaland remain unclear.
Nagaland’s oil and gas resources are once again drawing the attention of a major private energy company. Vedanta Oil & Gas Limited (VOGL) has renewed its interest in the state’s hydrocarbon potential, placing Nagaland among the areas it sees as part of the Northeast’s emerging energy landscape.
At the North East Energy Summit 2026 – Nagaland Energy Chapter in Chumoukedima on Friday, the company reiterated its intention to unlock the region’s hydrocarbon potential, highlighting opportunities across underexplored oil and gas basins. Its representatives identified Assam, Arunachal Pradesh and Nagaland as areas where it sees scope for exploration.
The latest announcement, however, is not the beginning of Vedanta’s interest in Nagaland. The company already has two oil and gas exploration blocks whose geographical coverage extends into parts of Wokha and Mokokchung districts. It has also included Nagaland in its wider investment plans for the Northeast.
Yet, while the company’s regional ambitions are substantial, what they mean specifically for Nagaland remains an open question.
An exploration footprint in Nagaland
Vedanta’s connection with Nagaland is linked to two blocks awarded under the Centre’s Open Acreage Licensing Policy (OALP): AA-ONHP-2017/1 and AA-ONHP-2017/4.
The first block covers 715 sq km, including parts of Wokha district, while the second covers 839 sq km, including parts of Wokha and Mokokchung, alongside areas in Assam.
The exploration proposals submitted in 2019 indicated the scale of the company’s initial plans. The first block envisaged seismic surveys and 46 exploratory and appraisal wells, with an estimated project cost of Rs 1,125 crore. The second proposed 29 wells.
But the presence of Nagaland within the geographical boundaries of the blocks does not mean that drilling was planned throughout those areas. The environmental impact assessment for AA-ONHP-2017/4 specifically stated that its proposed exploratory operations would be confined to the Jorhat portion in Assam and would not extend into Wokha or Mokokchung.
The distinction is important because the company’s documented exploration activity has so far been clearer in Assam.
Its environmental compliance report for October 2024 to March 2025 recorded two exploratory wells drilled in Golaghat district. The company reported that neither resulted in a commercially viable discovery and that both wells were plugged, with the sites restored.
The available documents do not establish comparable drilling activity in Nagaland.
The investment promise
Vedanta’s interest in Nagaland also forms part of a wider investment pitch for the Northeast.
At the Rising Northeast Investors Summit in May 2025, Vedanta Group chairman Anil Agarwal announced an investment plan of Rs 80,000 crore across six Northeastern states. Of this, Rs 50,000 crore had earlier been announced for Assam, while an additional Rs 30,000 crore was proposed across Arunachal Pradesh, Nagaland, Tripura, Meghalaya and Mizoram.
The proposed investments covered oil and gas, critical minerals, refining, power transmission, renewable energy, optical fibre, technology and data centres.
However, the company did not specify how much of the proposed Rs 30,000 crore would go to Nagaland, or how much would be directed towards oil and gas exploration in the state.
In September 2026, Vedanta Oil & Gas announced a partnership with Beicip-Franlab India to accelerate exploration across nine OALP blocks and one Discovered Small Field block in the Northeast. The company cited potential resources of up to 300 million barrels of oil equivalent across the portfolio, without giving a state-wise breakdown.
The latest Chumoukedima summit announcement has again placed Nagaland within the company’s Northeast ambitions, but did not bring a specific investment figure, drilling schedule or operational commitment for the state.
Why Nagaland’s oil sector matters now
For Nagaland, the renewed corporate interest comes against the backdrop of a long and complicated history with petroleum extraction.
Oil was discovered at Changpang in Wokha district in 1973, and production began in 1983. Operations were halted in 1994 following disputes over royalty payments and production beyond the permitted limit.
The state subsequently notified the Nagaland Petroleum and Natural Gas Regulations and Rules in 2012, seeking to establish its own framework for exploration and extraction. However, questions over regulatory authority and the ownership of natural resources have continued to affect the sector.
A significant development came on June 11, 2026, when the Centre, Assam and Nagaland signed a tripartite memorandum of understanding to facilitate mineral oil operations in designated areas along the inter-state boundary. The agreement provides for coordination and operational continuity in identified areas of interest.
Union Home Minister Amit Shah said Nagaland had agreed to facilitate oil exploration beyond the six designated fields across the state. However, the agreement concerns identified boundary areas and should not be interpreted as blanket operational permission for any company.
The legal position has also remained contested. In March 2026, the Gauhati High Court closed a suo motu public interest litigation concerning Nagaland’s 2012 petroleum regulations, holding that the dispute over legislative competence between the Centre and the state fell within the Supreme Court’s exclusive jurisdiction under Article 131. The court did not decide the constitutional validity of the regulations on merits.
These developments form part of the changing environment in which companies interested in Nagaland’s hydrocarbon resources must operate.
From interest to investment
At Friday’s summit, Nagaland Power and Parliamentary Affairs Minister KG Kenye urged government departments, industry representatives, public sector enterprises and financial institutions to identify priority investment opportunities, prepare viable projects and improve coordination between government and industry.
He also called for practical mechanisms to follow up on commitments made during the summit, with clearly identified priorities, responsibilities and timelines. He expressed hope that the proposed NEES Declaration would provide a starting point for sustained cooperation.
Vedanta’s representatives – chief development officer Graham Richardson, director, Northeast, Balu Govind Meempat, and deputy director, Northeast, Avishkar Chauhan – highlighted the region’s underexplored basins and said advanced technology, supportive policy frameworks and cooperation between governments and industry would be key to unlocking their potential.
The company also referred to its experience in Barmer, Rajasthan, and its Rudra discovery as strengthening its confidence in the region’s hydrocarbon prospects. The announcement did not identify Rudra as a Nagaland discovery.

For Nagaland, the question is no longer simply whether companies see potential in its oil and gas resources. It is how that interest can be translated into actual exploration, investment and economic benefits, while addressing the state’s concerns over resource ownership, landowner rights, environmental protection and revenue sharing.
Vedanta has placed Nagaland within its exploration footprint and wider Northeast investment ambitions. But the distance between that interest and an operational project in the state remains to be bridged.
The company’s latest statement has renewed its pitch. Whether it leads to a concrete exploration and investment roadmap for Nagaland is what remains to be seen.
