What does Yemen s halting of operational processes at Saudi oil facilities in the south mean

These facilities are distributed among oil refineries, the largest of which is located in Jizan; it is considered one of Saudi Arabia’s largest refining projects, with a production capacity of up to 400,000 barrels per day of Arab heavy and medium crude, in addition to producing high-quality petroleum derivatives such as low-sulfur diesel and gasoline.
These refineries, located within the Jizan Industrial City, are still burning at the time of writing this report.
In neighboring Najran, Saudi Arabia retains large storage and distribution facilities; these facilities are designated for supply and strategic storage of petroleum products to ensure the continued flow of fuel in the Najran region and the southern border areas.
In Abha, part of the Asir region, there is also a fuel distribution station, a key strategic facility used for storing and distributing petroleum products and fuels to meet energy needs in the south as well.
Add to that the Shaybah oil field, one of the largest liquefied gas production fields in the Empty Quarter desert on the Yemeni border.
