A ballistic missile hit an office tower in Saudi Aramco's Dhahran headquarters complex late on October 13, per a company source cited by Reuters; the energy ministry said there was a limited fire and no injuries or deaths. Three people with direct knowledge told Reuters the damage was extensive, with fire spreading between the sixth and tenth floors and the floors holding the chief executive's office severely damaged. The complex hosts an operations centre that helps oversee Aramco's rigs, refineries, terminals and pipelines; eastern operations continued normally, some staff were sent home and some functions moved abroad, and Aramco did not comment. On October 14 the Houthis claimed the strike plus attacks on Riyadh's airport and an Aramco refinery in Riyadh, unconfirmed, and declared airports and oil facilities legitimate targets.^1,2,3

The Singapore-flagged container ship GFS Pride, about 2,824 TEU, was reported sunk near the Strait of Hormuz on October 14 after a projectile hit, with containers floating, per maritime security sources and a Pakistan navigational warning cited by Reuters; IMO data make it the second vessel to sink since the conflict began on February 28. UKMTO said on October 13 that a container ship and a tanker were hit by unknown projectiles inside the strait, per Reuters. Two senior Iranian officials told Reuters that Iran changed its attack tactics about ten days ago against ships it considers in violation of its restrictions, plans to extend operations to the Gulf of Oman and beyond, and aims to keep oil prices high before the US midterms; one said 'complete closure' was coming. JMIC rated the threat to merchant shipping 'severe'.^4,5,6

At least seven of the 12 large storage tanks at the Novoshakhtinsk refinery's oil-loading terminal in Rostov-on-Don were out of service after the October 10 drone strike, per OSINT analysts at Astra cited by Militarnyi on October 12, who said the fire had been put out and footage that afternoon showed smoke but no open flame. Another tank at the terminal exploded on October 13, per footage from monitoring Telegram channels reported by Ukrainska Pravda, which did not give a cause. Neither figure has been confirmed by the operator or Russian officials.^7,8

The IEA said in its October oil market report that the premium diesel commands over crude hit a record of almost $95 a barrel in September, and that counter-seasonal stock draws ahead of autumn refinery maintenance and winter could keep diesel supply constrained well into 2027, per Reuters. The agency put Middle East Gulf to Asia VLCC freight at around $36 a barrel in early October, more than five times its pre-war level, with US Gulf Coast to China above $37. Margins for Asian refiners running medium sour crude turned negative in September, per the IEA.^9,10

ExxonMobil's Stabroek group, with Chevron and CNOOC, has told Guyana it expects to need about 2 bcf/d of gas for reinjection to meet crude targets, and Guyana may scale back Fulcrum LNG's planned 6 mtpa floating LNG project to start at up to 3 mtpa, two people close to the talks told Reuters. The government is also weighing dropping exports and keeping gas for domestic power and petrochemicals; no decision has been made, and minister Vickram Bharrat declined to comment. ExxonMobil said it is working with Guyana on plans that maximize resource recovery.
