Saudi Arabia Accelerates Major Oil Pipeline Expansion to Bypass Blocked Persian Gulf Shipping

Dhahran, Saturday, 24 October 2026.
Saudi Aramco plans to raise pipeline export capacity to 10 million barrels daily, yet persistent drone strikes and multi-year construction will prevent immediate global oil price relief.

Strategic Shift: Aramco’s East-West Pipeline Expansion to Mitigate Strait of Hormuz Risks

Saudi Aramco (TADAWUL: 2222) announced plans to expand the East-West Crude Oil Pipeline (Petroline) capacity from its current 7 million barrels per day (bpd) to 10 million bpd over the next two to three years [1][2][3][5]. The initiative aims to bypass the Strait of Hormuz, a critical maritime chokepoint that has been severely disrupted since the U.S.-Israel military action against Iran on 28 February 2026 [4]. The Strait of Hormuz, historically handling 20% of the world’s seaborne oil, has seen exports plummet to 44% of pre-war levels, averaging just under 9 million bpd in September 2026 [3]. This expansion is a direct response to the ongoing security threats, including repeated Houthi drone strikes on the Petroline, which have forced precautionary shutdowns and temporary reductions in throughput [1][3][4].

Geopolitical Backdrop: Escalation and Infrastructure Vulnerabilities

The Petroline, spanning 1,207 kilometers (750 miles) from the Abqaiq processing hub to the Red Sea port of Yanbu, has become a lifeline for Saudi Arabia’s oil exports amid the crisis [3]. The pipeline’s capacity was fully utilized by 28 March 2026, but attacks—such as the 9 April 2026 strike on a pumping station that reduced throughput by 700,000 bpd—have underscored its vulnerabilities [1][3]. Drone strikes in May 2019, September 2026, and October 2026 further highlight the infrastructure’s exposure to regional conflicts [1][3][4]. Despite these challenges, the pipeline has facilitated a shift in export routes, with Ras Tanura’s exports surging to 3.6 million bpd in September 2026 from less than 1 million bpd in August, as refiners in Asia-Pacific adapted to the disrupted supply chains [5].

Economic Implications: Price Relief or Persistent Volatility?

Analysts suggest that while the expansion could add 2% more oil to the global market—potentially easing prices—significant uncertainty remains [1][3]. Gilbert Metcalf, a former U.S. Treasury official and visiting professor at MIT Sloan, cautioned that the pipeline’s vulnerability to attacks and potential refinery capacity constraints may limit immediate price relief [1][3]. The global oil market, which averaged over 24 million bpd in the week of 18 October 2026—exceeding pre-war levels of 23.3 million bpd—faces ongoing risks from supply disruptions and geopolitical tensions [5]. Metcalf noted that even with increased pipeline flow, the Strait of Hormuz’s closure would not be alleviated, leaving global supply chains exposed to elevated risk premiums [1][3].

Operational Challenges: Repair Timelines and Strategic Adjustments

The Petroline’s operational recovery has been gradual. After a September 2026 drone strike forced a temporary shutdown, flows recovered to 5.5 million bpd, with exports resuming at Yanbu at reduced levels [5]. Aramco implemented temporary bypasses to restore 75% of capacity, targeting 4 million bpd in the interim [5]. Permanent repairs, particularly to three damaged pumping stations, are expected to take weeks, delaying full restoration [5]. Meanwhile, the company is conducting engineering studies for additional export routes to reduce reliance on vulnerable corridors [2][3][6]. These efforts reflect a broader strategy to stabilize supply amid the ongoing conflict, which has already resulted in the loss of approximately 3 billion barrels of oil supply [5].
