Global sourcing, trading, and logistics for heavy and light crude oil, connecting producers, refiners, and qualified buyers across key energy markets.
Crude oil is the primary feedstock for refined products such as gasoline, diesel, jet fuel, and petrochemicals, and it is broadly classified into light and heavy grades based on density, viscosity, and API gravity. Petrolodex facilitates the supply of both light, sweet crude oils favored for high yields of premium fuels and heavier, denser crudes that serve complex refineries and heavy product demand. Through a network of producers, national oil companies, and trading partners, we help buyers secure the right crude basket to match refining configuration, product slate, and commercial objectives.
Heavy crude oil is a highly viscous, dense petroleum that does not flow easily and has a lower API gravity than lighter grades. It is typically defined as crude oil with an API gravity below roughly 20–22° API, with extra-heavy oil often below about 10° API, depending on the classification used. Heavy crudes usually contain more asphaltenes, sulfur, metals, and other high–molecular weight components, which increases processing complexity.
Because heavy crude requires more advanced refining processes—such as coking, hydrocracking, and thermal upgrading—it tends to sell at a discount to light, sweet oils. However, refineries that are configured for heavier feeds can capture value by converting these grades into a mix of fuels and heavy products such as residual fuel oil and asphalt.
Light crude oil is liquid petroleum with low density and low viscosity that flows easily at room temperature. It typically has a relatively high API gravity, often above about 31° API in many classifications, and usually contains a higher proportion of lighter hydrocarbon fractions. These characteristics make light crude easier and less energy-intensive to refine into high-value products such as gasoline, diesel, and jet fuel.
Because it requires less complex processing and yields more premium transportation fuels, light sweet crude generally trades at a price premium compared to heavier, sour grades. Benchmarks such as West Texas Intermediate (WTI) and Brent are widely referenced examples of light crude oils in global markets.
The Solutions
Step 1
Petrolodex sources directly from producers, national oil companies, and established supply networks to trade a full range of heavy and light crude grades. Whether your refinery processes light sweet crude or heavy sour grades for complex coking units, Petrolodex delivers the right specification under its own principal trading terms.
Step 2
Single-grade sourcing limits refinery flexibility. By combining heavy and light barrels, refineries can target desired API gravity, sulfur content, and product yield profiles, improving utilization and economics. Our team helps structure blended slates that optimize crude diet for maximum profitability.
Step 3
Once trade documents are signed and logistics are confirmed, Petrolodex coordinates all transportation, storage, and inspection milestones through to delivery. Full title transfer documentation is provided at the point of loading or delivery, with compliance records maintained throughout.
Supporting buyers seeking balanced crude slates, individual grade exposure, or opportunistic purchases across heavy and light streams
Range of crude grades from light sweet to heavy sour matched to refinery needs
Blending expertise to target API, sulfur, and yield profiles
Coordinated transportation and storage in key crude hubs
Benchmark spread monitoring to time purchases and hedge exposure
Direct access to producers, national oil companies, and trading partners across key crude exporting regions. Established relationships ensure consistent supply of both light and heavy grades matched to refinery specifications.
Blending services to create optimized crude slates targeting specific API gravity, sulfur content, and product yield requirements. Maximize refinery utilization and economics through strategic crude diet optimization.
Coordinated crude tanker operations, storage facilities, and terminal logistics across major export/import hubs. Complete logistics management from loading port to refinery intake aligned with operational schedules.
Monitoring benchmark spreads between light sweet and heavy sour grades helps buyers time purchases, hedge exposure, and plan refinery runs more effectively. Market intelligence for optimized crude procurement decisions.
Heavy and light crude oils serve different refinery setups and downstream markets, but both are core to global fuel and petrochemical supply.
Often favor lighter, sweeter crudes to maximize transport fuel yields with lower upgrading costs. Simple distillation and hydroprocessing configurations benefit from easy-to-process light crude.
With cokers and deep conversion units integrate heavier, more sour crudes to generate value from discounted feedstocks. Advanced processing captures margins from heavy crude differentials.
Actively manage portfolios of heavy and light barrels to match regional demand patterns and crack spreads. Market makers optimize crude position across quality grades.
