The Magna Reserva Project: When Chávez succeeded in getting the world's largest oil reserve recognized

In order to quantify and certify the reserves of heavy and extra heavy oil located in the Orinoco Oil Belt, in 2005, President Hugo Chávez instructed the authorities of Petroleos de Venezuela Sociedad Anónima (PDVSA), through the Venezuelan Petroleum Corporation (CVP), to carry out an evaluation of the bitumen that was being traded internationally at the price of coal.

This idea of quantifying reserves arose from the need to evaluate the amount of bitumen that, by means of Orimulsion, was being processed and there was no clarity about the quantities that existed of “that mineral”.

The definitive geological discovery that catapulted Venezuela to first place in the world in oil reserves was the reclassification of bitumen as extra heavy oil. This transition occurred through a phased strategy that changed the international energy map forever:

During the 80s and 90s, in order to make Orimulsion viable, the country defended internationally that the resource under the Orinoco Belt was bitumen (a semi-solid, quasi-mineral substance), and, since it was not considered crude oil, it charged only 1% of royalties that did not add up to the quotas of the Organization of Exporting Countries of Oil (OPEC).

However, in the early 2000s, during the Government of Hugo Chávez, oil policy changed dramatically: experts in the field argued that “being at deep reservoir temperatures, the resource flows naturally and, therefore, is technically extra heavy crude oil”. When the legal term changed, the resource stopped being treated as a cheap fuel similar to coal and began to be valued under the standards of the international oil refining market.

Once OPEC formally classified bitumen as oil, Venezuela obtained the right to quantify and certify it to the world as proven oil reserves. To achieve this, in 2005, the Magna Reserva Project was created.

PDVSA divided the Orinoco Belt into dozens of analytical blocks and invited more than 20 state and other national companies from around the world (including firms from Russia, China, India, France and Brazil) to carry out joint drilling and petrophysical evaluation studies. The objective was to demonstrate with auditable international methodologies that this extra heavy crude oil could be extracted in an economically viable way using modern horizontal well technology and diluents.

Official OPEC certification

As the project's audits progressed, the country's proven reserve numbers grew at an unprecedented rate:

· Before the project (90s): The nation declared conventional crude oil reserves that were around 70 thousand and 80 billion barrels.

· The definitive leap (2010 - 2011): After completing the certification of the Belt, OPEC made it official that the country had reached more than 297 billion barrels of oil in proven reserves.

With this update, Venezuela formally surpassed Saudi Arabia, which averaged 265 billion barrels and consolidated its position at the top of the world in oil rank-in-g, a position that is maintained to this day with more than 303 billion barrels reported.

The Magna Reserva Project proposed by the Bolivarian Government in 2005 not only redefined the national energy map, but also transformed global geopolitics by making it official that the Venezuelan subsoil houses the highest concentration of crude oil on the planet. This historic certification demonstrated that the reserves of the Orinoco Oil Belt were not a bitumen that must be sold at the price of coal, but an asset of global strategic importance indispensable for the long-term energy future.
