Agreement signed for Rs 1,325 crore, 175-km pipeline at Duliajan
Indradhanush Gas Grid Limited (IGGL) and ONGC have signed a Rs 1,325 crore agreement for a 175-kilometre feeder gas pipeline at Duliajan in Assam, as reported on 14 October 2026. The deal covers the construction of the feeder pipeline, which will connect into the broader gas distribution network being developed across India's northeast.

IGGL's broader northeast pipeline programme
The Duliajan agreement is the latest addition to IGGL's active project pipeline across northeast India. Projects India tracks five existing IGGL natural gas pipeline grid projects, each valued at Rs 9,265 crore, spread across Arunachal Pradesh (Itanagar), Tripura (Agartala), Assam (Silchar and Guwahati), Meghalaya (Shillong) and Mizoram (Aizawl). The cumulative scale of these commitments underlines the scale of gas infrastructure investment being directed at the region.
The Duliajan feeder line, at Rs 1,325 crore, is a distinct and smaller-scope agreement linked to ONGC, whose upstream operations in Assam's Duliajan area have long been a significant source of domestic gas production.

Assam's position in India's petroleum and gas project landscape
Assam accounts for 67 of the petroleum oil and gas projects tracked across India by Projects India, placing it sixth among all states in this sub-sector. Maharashtra leads with 262 tracked projects, followed by Uttar Pradesh (205), Gujarat (191), Madhya Pradesh (90) and Andhra Pradesh (73). The northeast, while a smaller share of total project volume, carries disproportionately large individual project values given the scale of pipeline grid buildout under way.
Across the full sub-sector nationally, Projects India currently tracks 1,336 live projects, with 40 added in the past 90 days alone, reflecting sustained capital commitment in oil and gas infrastructure.
Stage distribution signals where procurement activity is concentrated
Of the 1,336 petroleum oil and gas projects tracked nationally, 548 are at the Under Approvals stage, 323 are at Construction Started, and 246 remain at Planning. A further 74 have received approvals and are moving toward procurement, while 49 are completed and 43 are on hold.
The large number of projects still Under Approvals — more than 41 per cent of the total — means a significant pipeline of future tendering and procurement activity is forming. Suppliers and contractors active in pipeline construction, gas processing equipment, and related civil works have a meaningful forward visibility window, particularly in states such as Assam and the wider northeast where greenfield grid development is ongoing.

What this means for suppliers and contractors
The Rs 1,325 crore Duliajan feeder pipeline agreement represents a defined, valued contract between two public-sector entities, making it an actionable lead for firms offering pipeline fabrication, laying and coating services, civil and earth-moving contractors, instrumentation and flow-measurement suppliers, and project management and inspection services familiar with northeast India's terrain and logistics constraints.
IGGL's five other tracked pipeline projects — each at Rs 9,265 crore — represent a much larger cumulative opportunity that is at varying stages of development. Contractors already mobilised or registered in Assam and neighbouring states are better positioned to respond quickly as those projects move from planning and approvals into active procurement. The Duliajan agreement, being already signed, also signals that IGGL is actively contracting and not merely at the feasibility stage.
More broadly, the concentration of petroleum and gas projects in the Under Approvals and Planning stages nationally means the current period is well suited for relationship-building and pre-qualification with project promoters, ahead of anticipated tendering. Projects India currently records zero open tenders in the Mining Projects sector, reinforcing that the near-term opportunity lies in tracking project progression rather than responding to live notices.
