The Middle East moves more hydrocarbons through pipelines than any other region on earth. From Saudi Aramco’s Master Gas System — the world’s largest gas gathering network — to the UAE’s Hormuz bypass crude line and the 24-inch Dolphin gas pipeline threading beneath the Arabian Gulf, the infrastructure underpinning global energy supply is concentrated here. This ranking of the top 10 pipeline companies Middle East covers the operators, state networks, and transmission systems that define regional energy flows in 2026.
How We Ranked the Top 10 Pipeline Companies Middle East
Entries are ranked by network scale, throughput capacity, and strategic significance to regional and global energy supply. State-owned pipeline operators are assessed as standalone infrastructure entities where they operate independently of the broader national oil company. Cross-border pipelines are ranked on total network length and multi-country reach. Joint ventures appear under the primary operating entity.
1. Saudi Aramco — Master Gas System & SAPLINE
Saudi Aramco’s Master Gas System (MGS) is the largest gas gathering and processing network in the world, spanning over 14,000 km across the Kingdom. It gathers associated gas from oil fields, processes it, and distributes it to power stations, desalination plants, and petrochemical complexes. Throughput exceeds 10 billion cubic feet per day. Complementing the MGS, the Saudi Petroleum Pipeline (SAPLINE) runs 1,200 km from the Eastern Province to Yanbu on the Red Sea, carrying crude oil west of the Strait of Hormuz and providing a bypass capability of up to 5 million barrels per day. No other pipeline operator in the region approaches this combined scale.
2. ADNOC Gas Pipeline Assets — Abu Dhabi
ADNOC Gas Pipeline Assets is a publicly listed infrastructure entity operating 38 pipelines across 982 km of the Abu Dhabi network. ADNOC holds a 49% stake, with the remaining 51% held by a consortium of global infrastructure investors including BlackRock, Global Infrastructure Partners, and others who paid $4bn for the stake in 2019. The pipelines carry natural gas and condensate from Abu Dhabi’s onshore fields to processing facilities, power plants, and export terminals. In 2026, the entity continues to generate stable lease revenues under a 20-year agreement — a model that has attracted significant long-term institutional capital to Gulf pipeline infrastructure.
3. Abu Dhabi Crude Oil Pipeline — ADCOP
The Abu Dhabi Crude Oil Pipeline (ADCOP) is a 370 km strategic bypass running from Habshan in the Abu Dhabi interior to the export terminal at Fujairah on the Gulf of Oman. Operated by IRSHAD (International Petroleum Investment Company’s pipeline subsidiary, now under ADNOC), it carries up to 1.5 million barrels per day and eliminates Strait of Hormuz exposure for UAE crude exports entirely. In a region where Hormuz closure risk is priced into every supply contract, ADCOP is one of the most strategically significant pipeline assets in the world. Fujairah’s storage capacity — now exceeding 14 million barrels — has grown in direct response to ADCOP’s bypass capability.
4. Dolphin Energy — UAE-Qatar-Oman
The Dolphin Energy pipeline is the first cross-border natural gas pipeline in the Middle East, running 364 km subsea and onshore from Qatar’s North Field processing facilities at Ras Laffan to the UAE at Taweelah, with an onward spur to Oman. Owned by Mubadala (51%), Total Energies (24.5%), and Occidental Petroleum (24.5%), it delivers up to 2 billion cubic feet per day of gas to UAE power and industrial users. Dolphin demonstrated that cross-border gas trade was viable in a region historically resistant to energy interdependence. The pipeline continues to supply a significant portion of the UAE’s gas requirements in 2026.
5. Iraq Oil Pipeline Company (SCOP) — Basra to Ceyhan
Iraq’s State Company for Oil Projects (SCOP) operates the Iraqi pipeline network connecting southern Basra oilfields to the Turkish Mediterranean port of Ceyhan via the 970 km Iraq-Turkey Pipeline (ITP). At full capacity the route moves over 350,000 barrels per day, though political disruptions between Baghdad and the Kurdistan Regional Government have repeatedly halted flows since 2023. The southern export infrastructure — the Strategic Pipeline and offshore Basra terminal jetties — handled over 3.2 million bpd in 2025, making Iraq’s southern route by far its most reliable export corridor. SCOP ranks here on network significance despite the ITP’s operational challenges.
6. Arab Gas Pipeline — Egypt, Jordan, Syria, Lebanon
The Arab Gas Pipeline (AGP) spans approximately 1,200 km from Arish in Egypt through Jordan, Syria, and on to Lebanon, with planned extensions into Turkey that were never completed. Originally designed to move Egyptian gas northward at up to 10 billion cubic metres per year, the pipeline has operated well below capacity since Egyptian domestic gas constraints emerged in the 2010s and Syrian conflict disrupted the northern segment. In 2026 the AGP is partially operational, carrying LNG-derived gas from Egypt’s revived export programme through Jordan. Its infrastructure remains the backbone of any future Levant gas transit plan and retains strategic ranking despite inconsistent throughput.
7. Kuwait Oil Company — Gathering & Export Network
Kuwait Oil Company’s (KOC) pipeline network serves all upstream gathering, processing, and export functions within Kuwait. The system connects Kuwait’s major oilfields — Greater Burgan, Raudhatain, Sabriya — to the Mina Al Ahmadi refinery and export terminal complex, which handles over 2 million barrels per day of crude and refined products. KOC has been executing a sustained network upgrade programme under Kuwait’s Development Plan, targeting increased throughput capacity to support production growth toward 4 million bpd by 2040. The pipeline network is entirely domestic, but ranks here on throughput volume and the scale of the asset base underpinning one of the world’s largest crude exporters.
8. Oman Gas Company (OQGN) — National Gas Network
Oman Gas Company, now operating as OQGN under the OQ Group umbrella, is the transmission system operator for Oman’s national gas grid. The network spans over 3,300 km, connecting upstream production fields in Fahud, Saih Nihayda, and the southern Salalah region to industrial users, power generators, LNG export facilities, and the Sohar industrial port. OQGN operates under a regulated tariff structure and is the sole gas transmission entity in the Sultanate. In 2026, Oman’s pipeline capacity is under pressure from growing LNG feedgas demand as Oman LNG and BP’s Khazzan project continue to expand output — a constraint OQGN is addressing through a northern pipeline loop investment.
9. Bapco Upstream (formerly Tatweer Petroleum) — Bahrain
Tatweer Petroleum, rebranded as Bapco Upstream following Bahrain’s national energy company restructuring, operates the pipeline infrastructure connecting Bahrain’s onshore and offshore oilfields to the Bapco refinery at Sitra and to crude export facilities at Sitra Marine Terminal. The network is compact by regional standards — Bahrain’s Awali field is one of the oldest in the Middle East — but the pipeline system handles output from both Bahrain’s own reserves and its share of the Abu Safah offshore field shared with Saudi Arabia. The restructuring into Bapco Upstream reflects Bahrain’s ambition to professionalize its upstream operations under a single corporate entity with dedicated infrastructure management.
10. Trans-Arabian Pipeline (Tapline) — Historical Network & Revival Debate
The Trans-Arabian Pipeline (Tapline) was once the longest oil pipeline in the world, running 1,213 km from Abqaiq in Saudi Arabia to Sidon in Lebanon. Completed in 1950, it carried Saudi crude to Mediterranean export markets for three decades before political disruption progressively shut it down — the Lebanese segment was the last section to cease operations in 1990. The Saudi-Jordan segment carried refined products until 2002. In 2026, Tapline features on this list because debate around its revival as a gas transit corridor from Saudi Arabia to Jordan and Lebanon has re-emerged in regional energy planning discussions. No final investment decision has been taken, but the right-of-way and corridor remain legally protected.
The Future of Middle East Pipeline Infrastructure
The Middle East pipeline landscape in 2026 is shaped by two converging pressures: the need to expand capacity to support continued hydrocarbon export growth, and the parallel imperative to reduce Strait of Hormuz dependence. ADCOP and SAPLINE already provide partial bypass capability for the UAE and Saudi Arabia respectively. Qatar’s North Field expansion — targeting 160 MTPA of LNG by 2030 — will require additional pipeline feedgas capacity from field to liquefaction train. Iraq’s southern export infrastructure faces sustained investment pressure as SCOP works to increase Basra capacity.
Cross-border connectivity remains limited compared to Europe or North America. The Dolphin pipeline stands almost alone as a functioning cross-border gas link. The projects that could change this — Saudi-to-Jordan gas supply, East Mediterranean gas export corridors, potential revival of Tapline routing — remain in planning or political negotiation rather than construction. For the global pipeline companies with Middle East exposure, the region offers some of the highest-margin infrastructure assets in the world alongside some of the highest geopolitical risk.
For operators and procurement managers tracking Middle East energy infrastructure, the North American pipeline network and European pipeline companies offer a useful benchmark for regulatory frameworks and tariff structures that the Gulf is progressively adopting. Regional convergence on transparent tariff regulation, as seen with ADNOC Gas Pipeline Assets’ listed structure, is the clearest signal that Middle East pipeline infrastructure is maturing toward institutional investment standards.
Which is the largest pipeline company in the Middle East in 2026?
Saudi Aramco operates the largest pipeline network in the Middle East by any measure. Its Master Gas System spans over 14,000 km and processes more than 10 billion cubic feet of gas per day. The SAPLINE crude bypass adds a further 1,200 km strategic route from the Eastern Province to Yanbu on the Red Sea.
Does the Middle East have any cross-border pipelines?
The Dolphin Energy pipeline is the primary functioning cross-border gas link in the region, running 364 km from Qatar’s Ras Laffan to the UAE and onward to Oman. The Arab Gas Pipeline connects Egypt, Jordan, Syria, and Lebanon but operates below original design capacity. The Iraq-Turkey Pipeline links Basra to Ceyhan on the Mediterranean but has faced repeated political disruptions since 2023.
What is the Abu Dhabi Crude Oil Pipeline and why does it matter?
The Abu Dhabi Crude Oil Pipeline (ADCOP) is a 370 km bypass route running from the Abu Dhabi interior to Fujairah on the Gulf of Oman, carrying up to 1.5 million barrels per day. It allows the UAE to export crude without passing through the Strait of Hormuz — a critical strategic asset given recurring closure risk in the region. Saudi Arabia’s SAPLINE provides a comparable bypass for Saudi crude exports.
How are Middle East pipeline companies ranked differently from upstream oil companies?
This ranking focuses specifically on transmission and pipeline infrastructure operators — the entities that move hydrocarbons between fields, processing facilities, and export terminals. Companies like ADNOC Gas Pipeline Assets and Oman Gas Company (OQGN) are assessed as standalone infrastructure businesses rather than as subsidiaries of national oil companies, reflecting the trend toward separating regulated pipeline assets from upstream production for capital markets and tariff regulation purposes.
Which Middle East pipelines are most at risk from geopolitical disruption in 2026?
The Iraq-Turkey Pipeline (ITP) has been the most disrupted, with flows halted repeatedly since 2023 due to disputes between Baghdad, Erbil, and Ankara. The Arab Gas Pipeline’s northern segment through Syria remains effectively non-operational. The Strait of Hormuz remains the systemic risk for the entire region — the ADCOP bypass and SAPLINE partially mitigate this for the UAE and Saudi Arabia, but Qatar and Kuwait have no equivalent bypass infrastructure in place.
