Assam-Nagaland Sign Historic Tripartite MoU for Joint Oil and Gas Exploration
On 11 June 2026, the Governments of India, Assam, and Nagaland signed a landmark tripartite Memorandum of Understanding (MoU) for joint exploration and production of crude oil and natural gas along their disputed border region covering over 1,000 square kilometres and six contested fields. This MoU creates a formal mechanism to resolve decades-long boundary and jurisdictional disputes by enabling coordinated hydrocarbon activities and establishing a 50:50 revenue-sharing model between Assam and Nagaland. The cooperation is expected to enhance the current extraction capacity of 1,000 to 1,500 barrels per day substantially, with projections estimating revenues from one field alone at over Rs 15,000 crore. The agreement is hailed as a significant step in advancing Northeast India's energy security, economic development, and cooperative federalism.

Background & Context
The Assam-Nagaland border area has been marked by boundary disputes and jurisdictional conflicts since the mid-1990s, limiting hydrocarbon exploration despite the region's rich reserves. Assam is one of India’s pioneering oil-producing regions, with historical significance centered at Digboi, while Nagaland has considerable untapped petroleum potential in the Naga-Schuppen Belt. The dispute hindered exploitation of these resources for decades.
This tripartite MoU represents a breakthrough by formally enabling cooperative exploration, extraction, and equitable sharing of revenues. The collaboration aligns with India’s broader goals of enhancing domestic energy production, reducing import dependency, and fostering regional economic progress and security in the Northeast.
