Product

Merey 16 is Venezuela's flagship export crude — a deliberately engineered blend of extra-heavy Orinoco Belt crude with lighter diluents, and serves as the country's OPEC basket marker. It ranks consistently as the lowest-priced crude in the OPEC basket.

Origin & Production

Merey originates from the Faja Petrolífera del Orinoco (FPO) — the Orinoco Oil Belt in eastern Venezuela — one of the world's largest accumulations of extra-heavy crude. In its raw state, Orinoco crude registers only 8–10° API and has the consistency of near-solid paste, making it unfit for transport or export without upgrading. PDVSA, Venezuela's state oil company, blends this extra-heavy crude with lighter grades or condensates at a 3:1 ratio (three barrels heavy to one barrel light) to produce the marketable Merey 16 blend. The primary export terminal is José Terminal (Puerto La Cruz, Anzoátegui State).

Key Physical Properties

Contaminants & Metals Burden

Merey carries a significant vanadium load (~262 ppm) and high sulfur (2.45–3.4% wt), placing it firmly in the heavy sour category. The high asphaltene content — a legacy of the Orinoco molecular structure dominated by complex high-molecular-weight aromatic rings — creates additional challenges for catalyst management and unit fouling in downstream processing.

Refinery Requirements

Due to its density, viscosity, and metals content, Merey cannot be economically processed at simple or medium-complexity refineries. The required configuration demands a high Nelson Complexity Index and includes:

• Vacuum distillation to recover incremental gasoil fractions

• Delayed coking or visbreaking for bottom-of-barrel conversion

• Hydrocracking for vacuum gasoil upgrading

• Deep HDS units for ULSD-spec products

• Metals-tolerant FCC catalysts to handle V/Ni deactivation

The primary refined products slate skews heavily toward asphalt, heavy fuel oil (HSFO), and petroleum coke, with secondary yields of diesel and gasoline depending on conversion configuration.

Market Role & Pricing

Merey is Venezuela's reference/marker crude, included in the OPEC Reference Basket since January 2009. It historically trades at the deepest discount within the OPEC basket — in 2025 the annual average was $56.68/bbl, the lowest of all 12 OPEC tracked crudes. As of early 2026, it was being offered to USGC refiners at roughly Brent minus $6/bbl. 

Primary Export Markets

• China — the dominant destination; Chinese independent "teapot" refineries in Shandong province are the largest buyers

• US Gulf Coast — coking refineries in Texas and Louisiana increasingly importing post-sanctions easing

• India and SE Asia — secondary markets with deep-conversion capacity
