Venezuelan Intesurf® technology would triple the production of the Belt

The imperative need to make heavy and extra-heavy oil from the Orinoco Belt move through pipelines has been the subject of permanent investigation by Venezuelan researchers, who in their search have created various technologies worthy of various reports that explain the whys of many of them. They sleep, in Venezuela, the dream of patents. One of them is Intesurf®.

Two years before the nationalization of the Orinoco Oil Belt, undertaken by the Bolivarian Government in 2007, a team of researchers began the search for the stimulation and improved recovery of oil from heavy and extra-heavy crude oil, which moves underground, but as soon as they appear on the surface, they solidify.
With this purpose, in PDVSA, specifically in its subsidiary Intevep, the idea of ​​finding a technology that “coldly” would provide greater mobility to the hydrocarbons of the Belt and, in this way, increase production and with it the percentage of oil. possible to be extracted with respect to that accumulated in the subsoil.

The idea was taken by the team of researchers, led by Dr. Pablo Manrique, who opened a line of research aimed at formulating chemical solutions aimed at modifying the conditions of the reservoir, with the aim of giving a “magical” fluidity to the crude oil. heavy and extra heavy, as viscous and compact as a “tooth remover”.

Years of research revealed Intesurf®, a technology capable of increasing crude oil extraction and considerably lowering production costs with reduced environmental impact.

Engineer Franklin Archer, who was a member of the team of researchers, explained that as it was an initiative of the workers, the new technology was part of the graft project conceived within the Socialist Strategic Plan 2016-2026. Suffice it to mention that it is designed for the exploitation of heavy and extra-heavy crude oil from the Orinoco Oil Belt; its application in other areas of the country is also feasible.

“This type of technology is 'unconventional' because it is not associated with any thermal or dilution method (which are those that reduce the viscosity of heavy and extra-heavy crude oil). These, the conventional ones, are foreign technologies, generally polluting that cause large disbursements in foreign currency,” he explained.

In fact, by working with technological patents owned by American and Canadian companies subject to and fearful of the unilateral and illegal coercive measures imposed by the United States, the four breeders located in the Jose Complex, in Puerto La Cruz, remain almost paralyzed and prevented from receive the diluted crude oil from the Merey 16 type Belt and, therefore, unable to transform it into another with a higher API gravity, that is, one that is better received in international markets due to its ease of being refined into gasoline, diesel, among others. .

So, to take the heavy and extra-heavy crude oil from the Belt to where the upgraders and the Puerto La Cruz refinery are, a diluent is added to the wells, usually naphtha, between 20% and 30%, which is imported. at prices per barrel much higher than the price per barrel of the resulting Merey 16 type oil.

The naphtha is added to the crude oil in the wells of the Belt and withdrawn at the end of its path, via pipeline, in Puerto La Cruz, a cycle during which there is always a residual loss that can reach up to 5%. Hence, any national solution that reduces foreign exchange disbursements caused by gasoline imports is welcomed by all Bolivarian missions.

The chemical solution proposed by Intesurf® is a mixture of surfactants that modifies the “wettability” of the reservoir and makes the crude oil flow. The injection of this formula makes the oil slide towards the producing well more “easily”, increasing its production over time.

“This solution is made from water with a “tiny” amount of chemical solution, which makes heavy and extra-heavy crude oil acquire greater mobility. Mobility allows our wells to reach even higher levels of productivity than conventional crude oil producers and, at the same time, significantly increases what is known as the recovery factor,” he said.

The recovery factor (FR) indicates the economically recoverable, extractable oil reserves. It is calculated in relation to the available technology to be used to sustain and increase production throughout the exploitation of the fields.

In the case of the Belt, the FR is 15%-20% of the 1.300 million barrels of original oil in place (Poes) immersed in that subsoil. The measure yields the largest proven oil reserves in the world, 272 billion barrels of crude oil. However, US research centers use technologies capable of doubling the FR calculated by Venezuela, with a high degree of certainty. This is how the International Energy Agency doubles those reserves by placing the recovery factor at 40%.

Above these figures, from the first laboratory tests, the Venezuelan Intesurf® demonstrated its potential by raising the recovery factor above 50%. This technology was tested in the field of stimulation and seeks its coming of age as improved oil recovery (EMR) technology, an effort of the direct and democratic management of the working class of PDVSA.

In fact, this scientific development carried out entirely in Venezuela demonstrated its effectiveness in stimulating more than 500 wells in the Belt.

Hence, Archer affirms that this new technology developed in the Bolivarian Revolution is essential for Venezuela to become a “small power.” “Intesurf® emerges as a true, effective and efficient alternative for the exploitation of our heavy crude oil from the Belt, the most valuable and precious to all Venezuelans,” he expressed.
