The North Field LNG expansion is QatarEnergy’s programme to increase Qatar’s LNG production capacity from 77 million tonnes per annum (MTPA) to 160 MTPA by the early 2030s — the largest single LNG capacity addition in the history of the industry. The programme centres on two integrated developments, North Field East and North Field South, drawing on the world’s largest non-associated gas reservoir and incorporating carbon capture and storage infrastructure from the outset. Final investment decisions have been taken on both projects, and construction is underway across multiple trains and associated facilities at Ras Laffan Industrial City.
The North Field: Scale and Geology
The North Field lies offshore Qatar’s northeastern coast beneath the Persian Gulf, covering an area of approximately 6,000 square kilometres. It is the world’s largest non-associated natural gas reservoir, containing estimated reserves exceeding 1,700 trillion cubic feet — sufficient to sustain Qatar’s current production rate for well over a century. The field is geologically continuous with Iran’s South Pars field, which occupies the Iranian side of the shared reservoir.
Qatar imposed a self-declared moratorium on new North Field development in 2005, citing the need for reservoir studies to ensure sustainable long-term extraction rates. The moratorium was lifted in 2017, clearing the path for the expansion programme that QatarEnergy subsequently designed around the findings of those studies. The reservoir data gathered during the moratorium period underpins QatarEnergy’s confidence in the field’s ability to support a near-doubling of production capacity without compromising long-term recovery rates.
All of Qatar’s existing 77 MTPA of LNG production draws exclusively on North Field feedgas, as does the entire expansion programme. The field also supplies Qatar’s domestic gas consumption, petrochemical feedstocks at Ras Laffan and Mesaieed, and the fertiliser and ammonia production that QatarEnergy is simultaneously expanding. For context on the existing production infrastructure the expansion builds upon, see the Qatargas: History, LNG Trains and Merger with QatarEnergy.
North Field East: The First Expansion Phase
North Field LNG Expansion East (NFE) is the larger of the two expansion phases, adding six new mega-trains at Ras Laffan with a combined capacity of approximately 32 MTPA. Each train is rated at around 8 MTPA — marginally larger than the Qatargas-2, 3, and 4 mega-trains commissioned during Qatar’s previous expansion wave — and uses updated liquefaction technology designed to reduce energy consumption and carbon intensity per tonne of LNG produced.
QatarEnergy took the final investment decision on North Field East in 2021. International oil companies participating in NFE include TotalEnergies, Shell, ExxonMobil, ConocoPhillips, and Eni — each holding minority equity stakes in individual train entities while QatarEnergy retains the operator position and dominant equity across the project. The IOC participation structure mirrors the joint venture model used across the existing Qatargas and RasGas trains, distributing both capital requirements and offtake obligations across partners with established downstream market access.
NFE is integrated with a dedicated carbon capture and storage facility designed to handle CO₂ separated during the liquefaction process. QatarEnergy has committed to capturing and storing 11 MTPA of CO₂ by 2035 across its operations, and the NFE CCS infrastructure forms the largest single contribution to that target. The integrated CCS design — rather than a retrofitted addition — allows the capture equipment to be optimised alongside the liquefaction trains from the outset, reducing both capital cost and operational complexity relative to post-build CCS installations.
North Field South: The Second Expansion Phase
North Field South (NFS) follows NFE with a further capacity addition targeting the intermediate milestone of 142 MTPA before the programme reaches its 160 MTPA ceiling. NFS adds four trains at Ras Laffan, each at approximately 8 MTPA, for an additional 32 MTPA of capacity. TotalEnergies and ConocoPhillips are among the confirmed participants in NFS equity structures, though the full partner lineup across individual train entities was not entirely finalised at the time of FID.
North Field South received its final investment decision in 2022, approximately one year after NFE. The sequential FID structure reflects both the capital requirements of the programme — committing to both phases simultaneously would represent one of the largest single capital commitments in energy history — and the need to sequence construction activity at Ras Laffan to avoid the infrastructure and labour bottlenecks that affected previous large-scale LNG buildouts in Qatar and Australia.
NFS also incorporates CCS from the outset, with CO₂ injection into saline aquifer formations beneath the North Field supplementing the dedicated geological storage sites identified during QatarEnergy’s reservoir studies. The combined NFE and NFS CCS infrastructure represents one of the most ambitious carbon management programmes associated with any LNG expansion project globally.
EPC Contracts and Construction Activity
The engineering, procurement, and construction contracts for the North Field expansion represent some of the largest EPC awards in the history of the LNG sector. Chiyoda Corporation, Technip Energies, Samsung Engineering, and McDermott International are among the contractors involved across the NFE and NFS work packages, with individual contract values running into the billions of dollars. McDermott International has been active across multiple Ras Laffan projects and holds positions in the expansion programme’s offshore and onshore scopes.
Construction activity at Ras Laffan accelerated through 2024 and 2025, with the site hosting simultaneous work across six new train foundations, associated utilities, CCS infrastructure, and expanded port facilities. The port expansion is required to accommodate the additional LNG carrier traffic that 160 MTPA of production will generate — a significant uplift from the six berths currently serving 77 MTPA of output.
The March 2026 Iranian strikes and the subsequent shutdown of existing Ras Laffan operations raised questions about construction continuity at the expansion site. QatarEnergy has not confirmed the extent to which active construction work was affected during the shutdown period, though the ceasefire and partial restart of production in April 2026 suggested the security situation was stabilising sufficiently for site operations to resume. For full coverage of the 2026 disruption, see QatarEnergy Ras Laffan: LNG Shutdown, Force Majeure and Restart.
Market Rationale and Competitive Position
QatarEnergy’s decision to pursue the North Field expansion at scale rests on a long-term demand thesis: that LNG will remain a critical transition fuel through the 2030s and 2040s as coal-to-gas switching continues in Asia, European buyers seek non-Russian supply alternatives, and emerging markets in South and Southeast Asia build out gas import infrastructure. The 160 MTPA target positions Qatar to supply approximately 25% of projected global LNG demand by 2030 — a market share that would consolidate its position as the dominant LNG exporter ahead of Australia and the United States.
The competitive pressure the expansion is designed to address is real. US LNG export capacity is growing rapidly, with Golden Pass and other projects adding supply. Australian projects are pursuing brownfield expansions. Qatar’s structural advantages — lowest-cost feedgas globally, shortest shipping distances to Asian markets via the Arabian Sea, and fully integrated CCS — are the basis on which QatarEnergy argues its expanded output will displace higher-cost competing supply rather than simply adding to a surplus.

What is the North Field expansion and what is its target capacity?
The North Field expansion is QatarEnergy’s programme to increase Qatar’s LNG production from 77 MTPA to 160 MTPA by the early 2030s. It comprises two phases — North Field East, adding approximately 32 MTPA across six trains with FID taken in 2021, and North Field South, adding a further 32 MTPA across four trains with FID in 2022. An intermediate milestone of 142 MTPA is targeted before the programme reaches full capacity.
Who are the international partners in the North Field expansion?
North Field East involves TotalEnergies, Shell, ExxonMobil, ConocoPhillips, and Eni as minority equity partners alongside QatarEnergy, which retains operator control and the majority equity position across all trains. North Field South involves TotalEnergies and ConocoPhillips among confirmed participants. The partner structure mirrors the joint venture model used across Qatar’s existing Qatargas and RasGas trains.
Why did Qatar impose a moratorium on North Field development and when was it lifted?
Qatar imposed a self-declared moratorium on new North Field development in 2005 to allow comprehensive reservoir studies to assess sustainable long-term extraction rates for the field. The moratorium was lifted in 2017 after the studies confirmed that the reservoir could support a significant capacity increase without compromising long-term recovery. The data gathered during the moratorium period underpins the technical basis for the 160 MTPA expansion programme.
How does carbon capture feature in the North Field expansion?
Both North Field East and North Field South incorporate carbon capture and storage infrastructure from the outset rather than as a retrofit. The integrated CCS design captures CO₂ separated during the liquefaction process and stores it in geological formations beneath the North Field. QatarEnergy targets 11 MTPA of CO₂ captured by 2035 across its operations, with the NFE and NFS CCS facilities forming the largest contributions to that target.
How does the North Field expansion affect Qatar’s competitive position in global LNG?
At 160 MTPA, Qatar would supply approximately 25% of projected global LNG demand by 2030, consolidating its position as the dominant LNG exporter ahead of Australia and the United States. QatarEnergy argues its structural advantages — lowest-cost feedgas globally, integrated CCS, and shorter shipping distances to Asian markets — position expanded Qatari output to displace higher-cost competing supply rather than add to a market surplus.
