Introduction to the Oil Refining Market 

The global Oil Refining Market is witnessing steady growth as refiners navigate shifting fuel demands and expanding petrochemical opportunities. The market was valued at USD 62.5 billion in 2025 and is projected to grow to USD 75.08 billion by 2031, at a CAGR of over 3% during the forecast period. This growth is supported by advancements in refinery integration, desulfurization upgrades, and the development of renewable diesel platforms. 

The Oil Refining Market Size is expanding as operators diversify fuel slates, optimize conversion processes, and adapt to regional regulatory frameworks. With crude flexibility and petrochemical integration becoming key differentiators, the Oil Refining Industry is evolving to balance profitability with sustainability imperatives. 

Trends & Developments in the Oil Refining Market 

  • Petrochemical Feedstock Expansion in Asia: Refiners in China, India, and Southeast Asia are increasingly integrating catalytic crackers, polypropylene, and naphtha processing units to capture higher-margin chemical products. Projects like CNOOC’s Ningbo expansion illustrate how investment in polymers boosts crude throughput while mitigating gasoline demand pressures. 

  • Desulfurization Retrofits for Low-Sulfur Fuels: Post-IMO 2020 regulations have accelerated investments in hydrodesulfurization units and premium bunker fuel production. These upgrades support Oil Refining Market Growth by increasing product flexibility and maintaining compliance with global fuel standards. 

  • National Oil Companies Leading Integration: NOCs such as Saudi Aramco and ADNOC are leveraging crude production advantages to develop integrated complexes, combining refining and chemical assets. These models strengthen export potential, optimize margins, and shape regional Oil Refining Market Share dynamics. 

  • U.S. Light Tight Oil Boom: Shale output growth has prompted investments in condensate splitters and flexible processing units, enhancing light crude utilization for gasoline and petrochemical feedstocks. Projects by Phillips 66 and Verde Clean Fuels demonstrate the impact of regional feedstock abundance on global market positioning.
