Orinoco Belt: Introduction

Mon, 09 Mar 2026 00:00:00 GMT

On January 7, 1936, Standard Oil of New Jersey drilled a well called La Canoa-1 near a small community in Anzoategui state. For 44 days, the well produced roughly 1,000 barrels of crude per day. Then the drillers gave up. The oil was too heavy, too thick, too difficult to extract with the technology of the era. They capped the well and walked away from what would eventually prove to be the largest petroleum deposit on Earth. The Orinoco Belt, known locally as the Faja Petrolifera del Orinoco, stretches approximately 600 kilometers from east to west and 70 kilometers from north to south, covering about 55,314 square kilometers of southern Venezuela. Beneath this unassuming strip of savanna and scrubland lies an estimated 1.2 trillion barrels of extra-heavy crude oil.

The scale of the Orinoco Belt's reserves defies easy comprehension. Petroleos de Venezuela S.A. (PDVSA) has estimated that up to 235 billion barrels are producible, which alone would make the belt the largest petroleum reserve in the world, edging ahead of Canada's Athabasca oil ...

Orinoco Belt: The Weight of Heavy Oil

Mon, 09 Mar 2026 00:00:00 GMT

Extra-heavy crude is not the oil of popular imagination. It does not gush from the ground in cinematic black fountains. It seeps, resists, and clings. Extracting it requires either heating the reservoir to reduce viscosity or diluting the crude with lighter hydrocarbons before it...
