According to Mordor Intelligence, oil and gas downstream market size market size in 2026 is estimated at USD 104.03 billion, growing from 2025 value of USD 100.16 billion with 2031 projections showing USD 125.74 billion, growing at 3.86% CAGR over 2026-2031.

This report is Segmented by Type (Refineries and Petrochemical Plants), Product Type (Refined Petroleum Products, Petrochemicals, and Lubricants), Distribution Channel (Direct Sales/Wholesale, Distributors/Commercial, and Retail), and Geography (North America, Europe, Asia-Pacific, South America, and Middle East and Africa). The Market Sizes and Forecasts are Provided in Terms of Value (USD).
Asia-Pacific and Middle Eastern projects, totaling 4.9 million b/d between 2024 and 2028, are tilting global economics toward these hubs, giving integrated operators scale and feedstock proximity advantages while compressing European and North American margins.
Petrochemicals already account for 14% of global oil demand and are expected to rise further, prompting refiners to reconfigure their operations toward naphtha cracking and aromatics extraction in integrated complexes, as exemplified by Saudi Aramco's Motiva and China's coastal mega-projects.
Global EV sales reached 14 million units in 2024, accelerating the decline in gasoline demand in Europe and certain segments of China, prompting refiners to shift their focus toward diesel, jet fuel, and petrochemicals.

Refineries accounted for 65.25% of the Oil & Gas Downstream market in 2025 and should advance at a 4.52% CAGR, a pace underpinned by asset-utilization upgrades and petrochemical add-ons. This segment benefits from a flexible configuration that toggles between transport fuels and chemical feedstocks based on real-time margin signals. Saudi Aramco's Motiva expansion and Reliance's Jamnagar complex exemplify the scale synergies that lower per-barrel costs and enhance hydrocracker yields. Integrated builds blur the lines with petrochemical plants, raising barriers for smaller standalone facilities.
Petrochemical plants, although holding a smaller 34.75% share, post a 4.72% trajectory as naphtha crackers and propane dehydrogenation units proliferate in the Asia-Pacific region. Operators bundle shared utilities, logistics, and hydrogen networks to exploit co-product valorization. Yet feedstock-price swings and competition from integrated mega-sites temper standalone economics. Overall, the Oil & Gas Downstream market size gains resilience from this dual-track capacity strategy.
The Asia-Pacific region leads with a 32.85% share in 2025 and is expected to grow at a rate of 4.92% annually due to capacity surges in China, India, and Southeast Asia, where demographic tailwinds, industrialization, and policy support converge. China's petrochemical pull counters peaking gasoline use, while Indian refiners chase export premiums to Africa and Latin America. Indonesia, Malaysia, and Thailand strengthen their product balance through hub-and-spoke logistics along vital sea lanes.
North America, despite a decline in gasoline demand, exploits ethane-rich shale to feed petrochemical crackers and hydrotreaters, thereby anchoring competitive cash costs. U.S. consolidators such as Phillips 66 retrofit units for renewable diesel to align with California's LCFS and federal SAF incentives. Canada's heavy-oil upgraders and Mexico's government-driven builds diversify feedstock slates, though financing hurdles persist for new standalone capacity.
Europe navigates declining fuel volumes under the Fit-for-55 umbrella by converting sites into bio-hubs producing HVO and SAF, while integrating CCS clusters to mitigate residual CO2. Middle Eastern projects, such as ADNOC's Ruwais Phase II, leverage gas-liquids streams and subsidized utilities to serve EU and Asian importers. Africa is witnessing emerging complexes in Nigeria and Angola, but it is contending with capital scarcity. Meanwhile, Brazil's Petrobras balances domestic demand coverage with volatility in currency and policy cycles, collectively steering the regional mosaic of the oil and gas downstream market.
