The Refining War
Why Guyana’s ‘Sweet’ Advantage Still Troubles Venezuela’s Heavy Recovery

While Marco Rubio’s plan to unlock Venezuela’s 300 billion barrels of oil could flood the market, Guyana isn’t waving the white flag just yet. In the world of energy, volume is a headline, but quality is the bottom line. As Venezuela begins its long walk back to “glory,” it faces a massive technical hurdle: its oil is essentially liquid tar, while Guyana’s is “champagne.”
Here is how Guyana’s Light Sweet Crude keeps it in the driver’s seat even as a titan wakes up next door.
1. The Refining Edge: “Ready to Wear” vs. “Bespoke”
Not all oil is created equal. Guyana’s crude (from the Liza and Payara fields) is Light and Sweet.+1
- Light: It has a high API gravity (near 40°), meaning it flows easily and is packed with the components needed for gasoline and jet fuel.
- Sweet: It has very low sulfur content.
In contrast, most of Venezuela’s reserves in the Orinoco Belt are Extra-Heavy and Sour. This oil is thick, sulfur-rich, and often requires “diluents” (lighter oils) just to make it liquid enough to pump through a pipe.

The Result: Any refinery can process Guyanese oil with minimal effort. To process Venezuelan oil, a refinery needs multi-billion-dollar “upgraders” or complex configurations. This gives Guyana a massive “Refining Premium”—its oil simply sells for more per barrel because it’s easier to handle.
2. The Production Efficiency Gap
Guyana has the “new car” advantage. Its production is handled by state-of-the-art FPSOs (Floating Production Storage and Offloading vessels) operated by ExxonMobil. These are essentially floating high-tech factories that have been online for less than six years.
Venezuela is dealing with a “vintage fleet.” After years of neglect, its pipelines are corroded, its wells are “watered out,” and its upgraders are often offline. While Rubio claims “no money” is needed for the transition, experts estimate it will take $100 billion and a decade of work to make Venezuelan production as efficient as Guyana’s is today.
3. The “ESG” and Carbon Premium
In 2026, the world doesn’t just care about how much oil you have, but how dirty it is to get.
- Guyana’s Edge: Because its oil is “light,” it requires less energy to refine, leading to lower greenhouse gas emissions per gallon of gas produced. Guyana is also leveraging its massive rainforests to claim “Net Zero” status for its oil operations.
- Venezuela’s Hurdle: Extracting and refining heavy, sour crude is energy-intensive. Furthermore, the previous regime’s lack of environmental oversight has left a legacy of leaks and methane flaring that Western investors, wary of ESG (Environmental, Social, and Governance) scores, will be hesitant to touch without massive clean-up guarantees.
The Economic Comparison at a Glance
| Feature | Guyana (Liza Blend) | Venezuela (Merey 16) |
| API Gravity | ~32° – 40° (Light/Medium) | ~16° (Extra-Heavy) |
| Sulfur Content | <0.5% (Sweet) | >2.0% (Sour) |
| Main Products | High-value Gasoline/Diesel | Low-value Fuel Oil/Asphalt |
| Lifting Cost | ~$25 – $35 / bbl | ~$45 – $60 / bbl (inc. diluents) |
The Verdict: Complementary, Not Just Competitive
While Venezuela has the quantity to shift global geopolitics, Guyana has the quality that keeps profit margins high. Ironically, the best-case scenario for the region might be a partnership: Guyana’s “Sweet” oil is the perfect diluent to help move Venezuela’s “Heavy” oil to market.
