Orinoco crude (also called Faja crude or extra-heavy crude) is not a single exported grade but rather the raw, unblended feedstock extracted from the Orinoco Oil Belt — the world's largest single accumulation of hydrocarbons — before upgrading or blending into exportable grades like Merey 16.
The Orinoco Oil Belt
The Faja Petrolífera del Orinoco (FPO) stretches roughly 600 km east–west across eastern Venezuela, covering approximately 55,000 km² in the East Venezuela Basin. It overlaps much of the Orinoco River valley and is divided into four operational areas from west to east: Boyacá, Junín, Ayacucho, and Carabobo.
The USGS estimates 513 billion barrels of technically recoverable heavy oil in the belt (range: 380–652 Bb), against a total oil-in-place that may exceed 1.2 trillion barrels — comparable to all known light crude reserves on Earth combined. Venezuela's officially stated proven reserves stand at 303 billion barrels, representing ~17.5% of the global total and the world's largest by that measure.

With API gravity as low as 4–8° in the deepest-quality zones, raw Orinoco crude approaches natural bitumen in character — denser than water, nearly immobile at reservoir and surface temperatures, and chemically dominated by asphaltenes and high-molecular-weight aromatic structures.
Geological Character
The oil is hosted in Cretaceous to Paleogene sands of the Oficina Formation at relatively shallow depths (300–1,500 m), which limits thermal gradient benefits on viscosity. The accumulation is the result of biodegradation of originally lighter crude migrating from the La Luna source rock — bacteria consumed the lighter fractions over geological time, leaving behind the heavy residue. Reservoir properties are actually favorable: high porosity (25–32%) and high permeability (1,000–5,000 md), meaning the challenge is crude mobility, not reservoir access.
Production Methods
Because raw Orinoco crude is essentially immobile at reservoir conditions, production relies on:
-
Horizontal wells with multi-lateral configurations to maximize reservoir contact and drainage
-
Cold heavy oil production with sand (CHOPS) in shallow zones
-
Steam injection / SAGD in deeper or tighter sub-areas
-
Electrical submersible pumps (ESPs) in virtually all producing wells
-
Diluent injection downhole or at surface to achieve pipeline-transportable viscosity
A 3:1 blending ratio (3 barrels Faja crude + 1 barrel condensate/light crude) is required to produce Merey 16 for export. Venezuela has historically relied on imported Iranian condensate and light crudes as diluents, creating a strategic supply chain vulnerability.
Upgrading Infrastructure (Mejoradores)
Before 2020, four upgrader plants (mejoradores) in the José Industrial Complex, Anzoátegui State, converted raw Faja crude into synthetic crude oils (SCOs) closer to 26–32° API:
| Upgrader |

| Petroanzoátegui (ex-Cerro Negro) |

| Petropiar (ex-Hamaca) |

| Petromonagas (ex-Terra) |

Most upgrader capacity was severely curtailed post-2017 due to US sanctions, investment collapse, and skilled-worker emigration. As of early 2026, PDVSA has been restoring output primarily through blending (Merey route) rather than full upgrading.
Current Production Status
Following a US–Venezuela diplomatic agreement in January 2026, sanctions relief paved the way for resumed exports. Total Venezuelan production approached 1 million b/d as of February 2026, with the Orinoco Belt contributing slightly over 500,000 b/d. Shipments surpassed 1 million b/d in March 2026. Chevron finalized a deal in April 2026 to trade offshore gas assets for an expanded Orinoco Belt footprint, signaling major IOC confidence in the belt's resurgence.
Market Position & Pricing
Without upgrading, raw Orinoco crude is worthless on international markets. Even as Merey 16, it traded at an estimated WTI minus $7–$10/bbl discount in pure gravity/quality terms, with additional logistical and geopolitical discounts layered on top. The BNEF estimate for the unblended heavy crude (no diluent) implies a ~$15–$20/bbl discount to WTI under normal market conditions. China's independent "teapot" refineries remain the dominant buyers, absorbing the bulk of all Orinoco-derived exports at steeply discounted prices.
