Core Insights - The article discusses the significant shift in Shandong Yulong Petrochemical's crude sourcing, primarily moving to Russian oil due to Western sanctions impacting access to other suppliers [4][3][2] Group 1: Supply Chain Changes - Shandong Yulong has transitioned from a diverse supply portfolio to relying almost entirely on Russian crude, securing approximately 350,000 b/d for November delivery compared to only 100,000 b/d earlier in the year [2][4] - The refinery's operational capacity is currently at about 90% of its 400,000 b/d design, with Russian crude now providing nearly all its feedstock [2][5] Group 2: Impact of Sanctions - Western sanctions have inadvertently created a new trade dynamic, linking Russian producers with sanctioned Chinese refiners like Yulong, which now operates almost exclusively on discounted Russian oil [4][3][9] - The sanctions imposed by the UK and EU have restricted Yulong's access to Western supplies, forcing it to adapt its sourcing strategy [4][3] Group 3: Operational Efficiency - Yulong's operational efficiency has improved due to the lower costs associated with sourcing Russian crude, which has offset the deflation in product prices and maintained profitability despite an oversupplied market [6][5] - The refinery has achieved record-high throughput in September and October, running at approximately 90% capacity [5] Group 4: Future Supply Considerations - Analysts express concerns about Yulong's ability to secure the heavy crude necessary for consistent product output, although some suggest that Russia's Urals blend could serve as a suitable substitute [8][7] - Gazprom Neft may redirect its Arctic ARCO crude to Yulong, potentially supplying the heavy feedstock needed for efficient operations [9]
