<span>The feedstock available to Saudi petrochemical companies should return to usual levels by the end of the month after </span><span>a temporary outage of more than half of the kingdom's oil production, according to two of the country's biggest downstream companies.</span> <span>Attacks on the world's biggest oil processing facility </span><span>and a field in the country's oil-rich Eastern Province </span><span>cut off 5.7 million barrels per day, or the equivalent of 5 per cent of global supply</span><span> earlier this month.</span> <span>Saudi Arabia, the world's largest oil exporter, continued to meet its contractual obligations to international customers by drawing on its </span><span>reserves and cutting back on feedstock supply to domestic refiners and pet</span><span>chems.</span> <span>Saudi Basic Industries Corporation</span><span>, the biggest listed company in the kingdom, had suffered a 40 per cent decrease in available feedstock in the immediate aftermath of the incidents. </span> <span>Yesterday, the company said in a statement to the Tadawul stock exchange, where its shares trade, that the loss of supply had been trimmed to<br/> 20 per cent, with “the expectation to reach normal levels by end of September”.</span> <span>Sabic said it was working to evaluate the financial effect of the attack and would disclose “any material developments in this regard”.</span> <span>Other companies had also reported supply disruptions ranging from 30 to 50 per cent of feedstock</span><span>, but the National Petrochemical Company said in a disclosure to the Saudi bourse yesterday that its supply </span><span>had "gradually improved" to reach normal levels on Thursday. The company </span><span>initially </span><span>faced a 40 per cent </span><span>reduction in feedstock supply from Saudi Aramco. </span><span>There was no "material financial impact" from the disruption, it added.</span> <span>Facts Global Energy in London said in a note last week that the restriction of supply to local petchems is likely to hit consumption of products such as liquefied petroleum gas and naphtha.</span> <span>Saudi Arabia is a significant exporter of LPG, selling 290,000 bpd on average in the first eight months of the year, and 220,000 bpd of naphtha during the same period. </span> <span>However, the kingdom’s petrochemicals sector is the main consumer of its local supply of both products.</span> "We expect both exports and domestic consumption will be impacted for both products, mainly in September and to a lesser extent in October," the consultancy said.
