Oil & Gas Pipeline Market 2026

The market spans transportation of crude oil, other liquid hydrocarbons, refined petroleum products and natural gas, together with connected storage and terminal services. Operators sell transportation or capacity access rather than necessarily selling the commodity. Producers need routes to market; shippers, utilities, power generators and industrial users need capacity and dependable delivery.

Enbridge’s portfolio illustrates liquids and gas transmission in North America, while Snam combines gas transportation with storage and regasification in Italy. Great Britain’s National Gas provides an example of a capacity-booking model for shippers. Commercial comparisons therefore need to distinguish the asset owner, network operator, shipper and end customer, as well as regulated access from negotiated contracts.

Ownership is changing alongside route economics. In Canada, TC Energy completed the separation of its liquids-pipeline business into South Bow in 2024; Keyera completed its purchase of Plains’ Canadian natural gas liquids business in 2026. These are completed ownership changes, not evidence that either transaction alone increased throughput.

Access rules are also moving. PipeChina’s June 2026 notice invited eligible shippers to apply for remaining capacity on operating gas facilities. Brazil’s regulator approved opening asset bases for five gas transporters in October 2026, but reserved permitted revenue and tariffs for a later phase. In Europe, the EU’s 2026 Russian-gas regulation imposes a phased prohibition with transitional exemptions for existing contracts.

Mexico illustrates the distinction between a project and an earning asset: Southeast Gateway entered service and TC Energy began collecting tolls from CFE in May 2025; regulated rates for potential additional interruptible users were approved separately in July.

Enbridge reported in 2024 that it was using Microsoft-supported AI in pipeline-related asset and maintenance information and had deployed Microsoft 365 Copilot to part of its workforce. This is evidence of a named operator’s adoption, not an independent measurement of savings or proof that the applications are common across the market.

For pipeline businesses, the potential commercial value is cumulative: better-organized information could support investment prioritization, contract review and customer responses alongside asset-related decisions. That remains a conditional opportunity. Buyers should distinguish a vendor demonstration, staff access and sustained use, and evaluate costs, data permissions and decision accountability before treating AI benefits as realized.

North America combines established liquids and gas transportation portfolios with cross-border connections; Mexico’s Southeast Gateway adds a contracted route for southeastern gas demand. In Latin America, Brazil’s entry-exit contracting framework makes access terms and subsequent tariff decisions important to shippers.

In Europe, gas-route choices are being reshaped by the EU’s phased restrictions on Russian imports, including transitional contract provisions. In the Middle East, Dolphin Energy’s Qatar–UAE–Oman gas system illustrates a cross-border supply business, but its arrangements should not be generalized to every regional corridor.

In Africa, the East African Crude Oil Pipeline is intended to connect Ugandan production to Tanzania’s export coast. TotalEnergies reported that construction was entering its final phase as of September 30, 2026; that is not evidence of commercial throughput. In Asia-Pacific, the China–Russia east-route gas pipeline’s full connection in 2024 illustrates an operating cross-border corridor, while access and demand conditions remain country-specific.

ASEAN has broadened its former Trans-ASEAN Gas Pipeline focus into wider oil and gas connectivity and security. That creates a cooperation agenda, not evidence that a single integrated pipeline market has been completed. BRICS likewise has a voluntary energy roadmap that prioritizes interconnection; it does not establish a common pipeline tariff or guarantee investment in a particular route.

For the European Union, the Russian gas phase-out changes the access framework in stages. The G7 price-cap coalition addressed seaborne Russian oil and related maritime services: it should not be mistaken for a pipeline-tariff policy, although changes in oil-trade routes may matter to connected infrastructure.

Within the GCC, Dolphin’s Qatar–UAE–Oman system demonstrates a specific cross-border gas channel; its additional export capacity depends on a future agreement with Qatari authorities, not an automatic group-wide expansion. NATO has a different buyer need: its petroleum-product system prioritizes military requirements, with commercial use of spare capacity permitted only when that priority is preserved.

North America and Latin America. In the United States, Enbridge’s liquids and gas assets connect pipeline demand to its wider North American portfolio. In Canada, the regulator reports growing Indigenous community ownership interests in existing pipelines, making governance and financing important commercial considerations. In Mexico, CFE is both an alliance partner and toll customer for Southeast Gateway; access for potential additional interruptible users required a separate rate decision. In Brazil, shippers can contract entry and exit capacity separately, while the October 2026 asset-base decision did not settle final tariffs.

Europe. In France, Teréga reported inbound gas flows from Spain in 2022, an example of interconnection serving supply diversification rather than proof of today’s flows. Germany’s regulator identified Norway, the Netherlands and Belgium as its largest gas suppliers in preliminary 2025 data, alongside German LNG imports. In Italy, Snam reported financing for the first phase of the Adriatic Line and related export infrastructure; the award is not completion of the entire project. Spain’s Enagás reported higher transported-gas demand in 2025, mainly from electricity generation and exports. In the United Kingdom, National Gas owns and operates Great Britain’s transmission system and shippers book capacity. Russia’s Power of Siberia provides a route to China; the EU phase-out separately constrains Russian gas access to that bloc.

Asia-Pacific. In Australia, APA owns Victoria’s transmission system while the Australian Energy Market Operator operates it under a regulated arrangement. In China, PipeChina’s application channel is for admitted shippers and remaining operating capacity; acceptance is not guaranteed. India’s regulator lists authorized pipelines and extensions, but authorization should not be equated with completion. Japan’s city-gas networks are organized by service area rather than as one nationwide pipeline. In South Korea, KOGAS links imported LNG terminals to its nationwide gas pipeline network.

• Choose the access model before committing capital. Where an existing network has an application or capacity-booking channel, assess eligibility and available capacity against the alternative of sponsoring new infrastructure. Build expansion assumptions around executable customer commitments, not the existence of a published application process.

• Separate anchor demand from follow-on sales. Mexico’s Southeast Gateway shows that a committed customer and rates for potential additional users are distinct. Favor partnership-led expansion where the anchor’s contract supports the investment; retain a smaller or staged option if additional demand or regulated rates remain uncertain.

• Price policy and ownership scenarios explicitly. Test European route investments against the phased Russian-gas rules and alternative supply arrangements. In Brazil, avoid treating the asset-base decision as a final tariff. In Canada, consider Indigenous equity participation alongside conventional ownership, with governance and financing terms agreed by the parties.

• Buy AI against a defined business case. Enbridge’s disclosed information tools and pipeline-related applications suggest separate budgets and measures for each use. Compare a limited deployment with existing workflows before broad rollout; require evidence of useful adoption and an accountable review process rather than assuming an advertised benefit transfers to every network.

This qualitative assessment compared inspected company portfolios and filings with regulator records, association material and intergovernmental documents. It uses records published from 2022 through 2026, including native-language records for Brazil, China and France. Project announcements, regulatory decisions and reported operation were treated as different commercial statuses.

Coverage is illustrative rather than a complete inventory of global pipelines, suppliers or contracts. Company statements about their own activity were not independently audited; public records do not establish all current utilization, profitability or customer adoption. No interviews, surveys or statistical market estimates were undertaken.

The commercial outlook turns on access to customers and routes as much as on new construction. Completed North American ownership changes, Mexico’s toll-earning Southeast Gateway and China’s shipper application process show different ways to participate; none guarantees returns for a future entrant.

Useful public milestones to watch include Brazil’s subsequent tariff decisions, implementation of the EU gas phase-out and whether EACOP moves from construction into commercial service. Contracted demand, usable capacity and the division of responsibilities between owners and operators will remain decisive questions for each opportunity.
