What Are the Differences Between Brent, WTI, and Other Types of Crude Oil?

Crude oil is one of the most valuable natural resources in the world, powering economies and industries across the globe. But not all crude oil is the same. In fact, there are dozens of varieties, each with its own unique properties, market value, and region of origin.

Among them, Brent and West Texas Intermediate (WTI) are the most widely known and traded benchmarks. However, many other crude oil types are also essential to global energy markets.

In this article, A&B IMPORT EXPORT—based in Saint-André, La Réunion and specializing in crude oil, Jet-A1, and EN590—explores the key differences between Brent, WTI, and other major crude oil types.

What is Crude Oil? A Quick Recap

Crude oil is a naturally occurring fossil fuel formed from ancient marine organisms. Once extracted, it must be refined into usable products like gasoline, diesel, jet fuel, and petrochemicals.

Each type of crude oil varies in :

• Density (API gravity) — Light or heavy

• Sulfur content — Sweet or sour

• Geographic origin

These differences affect the oil’s quality, market price, and refining complexity.

Brent Crude : The Global Benchmark

• Origin : North Sea (off the coasts of the UK and Norway)

• API Gravity : ~38–39 (Light)

• Sulfur Content : ~0.37% (Sweet)

Brent is the world’s most widely used crude oil benchmark, accounting for over two-thirds of internationally traded oil contracts. It represents a blend of oil from multiple North Sea fields, including Brent, Forties, Oseberg, and Ekofisk (BFOE).

Why Brent Matters :

• It is waterborne, meaning it’s easier and cheaper to ship globally.

• Its light and sweet nature makes it ideal for producing gasoline and diesel.

• It’s widely used for pricing oil exported from Europe, Africa, and the Middle East.

Usage :

Brent is used as a pricing reference for more than 70% of globally traded crude oils.

West Texas Intermediate (WTI) : The U.S. Benchmark

• Origin : Texas and surrounding U.S. regions

• API Gravity : ~39.6 (Very light)

• Sulfur Content : ~0.24% (Very sweet)

WTI is the main benchmark for U.S. crude oil. It is extracted primarily from inland oil fields and delivered to the storage hub in Cushing, Oklahoma, where it’s traded on the New York Mercantile Exchange (NYMEX).

Why WTI Matters :

• It is lighter and sweeter than Brent, making it slightly easier to refine into high-value fuels.

• It reflects domestic U.S. market dynamics and is often influenced by American supply/demand conditions and infrastructure bottlenecks.

Challenges :

• WTI is landlocked, which can limit its export flexibility compared to seaborne Brent.

• Infrastructure constraints (pipelines, storage) can create price disparities between WTI and other crudes.

Brent vs WTI : Key Differences

Feature	Brent Crude	WTI Crude
Origin	North Sea (Europe)	United States (Texas/Oklahoma)
API Gravity	~38.5	~39.6
Sulfur Content	~0.37% (Sweet)	~0.24% (Very Sweet)
Transport	Seaborne	Landlocked (pipeline-based)
Main Exchange	ICE Futures Europe	NYMEX
Pricing Influence	Global	Mainly North American
Refining Yield	High (gasoline, diesel)	Very high (gasoline, jet fuel)

Although WTI is technically slightly higher in quality than Brent, Brent usually trades at a premium due to its global accessibility and larger influence on international pricing.

Dubai/Oman Crude : The Asian Benchmark

• Origin : Middle East (United Arab Emirates, Oman)

• API Gravity : ~31 (Medium-heavy)

• Sulfur Content : ~2% (Sour)

Dubai and Oman crudes are used as pricing benchmarks in Asia, especially for oil traded between the Middle East and Asia-Pacific.

Key Points :

• Heavier and sourer than Brent or WTI.

• Preferred for pricing long-term contracts between Middle Eastern producers and Asian refiners.

• Typically trades at a discount to Brent due to lower quality and higher refining costs.

Other Notable Crude Types

Urals (Russia)

• Blend of heavy and light Russian crude.

• Heavier and sourer than Brent.

• Exports mainly to Europe and Asia.

• Now heavily impacted by sanctions and market shifts.

Bonny Light (Nigeria)

• Light and sweet (API ~35–37).

• Highly sought after for its easy refining and low sulfur content.

• Used as a pricing reference for West African crude exports.

Arab Light (Saudi Arabia)

• One of the most exported crudes globally.

• Medium in gravity (~33–34) and moderately sweet.

• Produced by Saudi Aramco, vital for Asian buyers.

Arab Heavy (Saudi Arabia)

• Extremely heavy crude.

• Requires upgrading before refining.

• High cost and environmental challenges.

How These Differences Affect Pricing

Crude oil types are priced relative to benchmarks like Brent or WTI. These differentials depend on:

• API gravity and sulfur content

• Proximity to market

• Refining complexity

• Market demand

• Political stability of the source country

For example :

• A sweet, light crude located near major shipping lanes will command a premium.

• A heavy, sour crude from a landlocked or politically unstable region may trade at a discount.

Why It Matters for Buyers and Traders

Understanding the differences between crude types is essential for:

• Refiners seeking specific yields (e.g., diesel vs. asphalt).

• Traders managing contract terms and logistics.

• Governments setting strategic petroleum policies.

• Importers estimating transportation, customs, and refining costs.
