What makes Venezuela valuable now is not what it produces. It is the routes it does not have to take.

The crisis in the Middle East is making something that usually complicates Venezuela's life more valuable: the characteristics of its heavy crude.

Brent is already at $100. Attacks on Saudi facilities and restrictions in Hormuz have the global market under pressure.

Inside some Texas refineries, though, something less obvious is happening. The disruptions are hitting the supply of heavy fuel oil, which is used to process residues from other fuels.

When there are problems with that feedstock, the refinery needs another way to feed those units. And that is where a unique opportunity appears for Venezuelan crude.

Kpler notes that Merey can help cover that need. When it is processed, the refinery obtains a large amount of material it previously had to buy separately. Part of that missing feedstock can now be obtained from Venezuelan oil.

At the beginning of the refining process, crude is usually separated into fractions. Some lighter than others. The heaviest leave a thick residue that still contains usable hydrocarbons, but that require more processing.

These coking units, or cokers, take on that residue. They use heat to break the heavy molecules and obtain lighter streams. Those streams then go through other processes until they can be turned into fuels.

Refineries of this type have a very particular relationship with heavy crude. They can extract value from a part of the barrel that is normally hard to use.

The Gulf Coast has about 1.6 million barrels a day of coking capacity. It has an entire infrastructure built to process exactly that difficult part of the oil.

And that is why Merey can gain value when certain feedstocks disappear. Its density really does complicate transportation and operations in Venezuela. But it also makes it possible to feed this kind of facility.

In the end the crude is still the same. What is changing is how the system benefits from it.

The refining system is still there

Venezuela's sanctions had interrupted a large part of its trade. But circumstances are now changing. Phillips 66 is resuming direct purchases from PDVSA. And it recently received three Merey allocations in July.

At 14 million barrels a day, the United States has become the world's largest oil producer. That does not mean it can produce every kind of crude. And that is exactly where the interest in Venezuela comes from.

For a facility with residue-conversion capacity, switching its supply to light crude also requires changing part of the plant. The decision depends on the equipment it already has, on oil prices, and on the products it wants to make.

Importing heavy crude while producing and exporting light crude are operations that can complement each other inside the same industrial system.

At the beginning of the year, shipments to the United States were around 300,000 barrels a day. By July of this year they were already around 800,000 barrels.

The refiners negotiating directly with PDVSA are now competing for the space opened up by the first flows after the reopening.

The point is that buying an available cargo solves a one-off need. Being able to build a relationship with recurring purchases can feed the refineries in a different way.

Mike Wirth has been looking for greater use of Venezuelan crude at Chevron so that it can compete with the alternatives in the region. That gives Venezuelan crude a strategic advantage against the Canadian heavy option.

A refinery can look for options without necessarily being willing to pay any price. For Venezuela, the real opportunity is to become that useful and reliable option again. Proximity to the Gulf helps, but the buyer also needs to receive the agreed quality and to have confidence in delivery times.

Oil does not solve the whole problem

Just when that reconnection seemed to offer an answer to the crisis, another constraint appears in the system. The problem is no longer only finding feedstock.

Phillips 66 noted that many Gulf Coast refineries are already running practically at maximum. Winter is approaching with little diesel in storage and limited processing capacity.

That changes the picture. Oil now has to pass through a facility before it becomes fuel. If that facility is already overstretched, receiving more crude does not automatically increase diesel production.

Part of the answer may be improving the blend that goes through the plant. Another is substituting the feedstock. Those are ways to get more out of existing equipment, even if they do not necessarily increase total volume.

That is where a more specific opportunity appears. The value of the barrel may lie in what it allows the same refinery to do.

Having interested buyers is not the same as finding unlimited demand for any increase in production.

And inside that scenario, Chevron's move takes on another scale.

Chevron's bet

Chevron's joint ventures plan to invest more than $7 billion in Venezuela over five years. The idea is to take production to 600,000 barrels a day. This same week, the company confirmed that it plans to double the number of rigs.

Chevron participates in Venezuelan production and also processes the barrels in Mississippi. It knows both ends of that industrial relationship.

That allows it to evaluate the resources in a more systemic way. The question of what happens in the field ends up connecting with what happens at its own facilities on the Gulf.

If we add the rise in fuel prices, Chevron's plan is definitely a long-term bet.

A maritime disruption can alter the market for a few days. Recovering production requires contracting new services, intervening wells, and making sure the facilities can sustain that increase. The industrial response takes much longer.

On the other hand, those new barrels coming from Venezuela have to deal with other physical constraints. The José refinery remains part of that chain. And its constant interruptions end up affecting how much oil can be shipped, as well as how regularly.

A company can be planning supply for the coming years while the market is still trying to resolve a seasonal shortage.

The commercial value of this new connection can rise well before its physical capacity can actually respond.

The SPR swap

Trump also wants to position Venezuelan oil as part of the United States' strategic reserve, known as the Strategic Petroleum Reserve, or SPR. The issue is still that Venezuelan heavy crude does not fit the specifications of the oil stored there.

The same barrel that is attractive to a high-complexity refinery can be inconvenient for a reserve. The facilities are completely different, both in their objectives and in their requirements.

Wright has even proposed a swap. Venezuelan crude for light oil. In that scheme, the first could go to refining and the second is ideal for strategic storage.

Venezuela could contribute to the reserve without its own barrels ending up as part of it.

That turn is important because it changes how the agreement is seen. Its usefulness would not depend only on taking Venezuelan oil directly to that place. It can be traded among the participants themselves. That way, the refinery can obtain feedstock it knows exactly how to process. And the government receives the kind of crude that is easy to store.

Everything is still a proposal. What is interesting is the exchange. Being able to convert access to one type of oil into another, using the same market and the existing infrastructure.

For Washington, the priority in the end is to recover the capacity to respond to a possible disruption. For a refiner, that translates into obtaining a profitable and reliable blend. For a producer, it consists of developing a source of revenue that can sustain it for years.

The possibility of bringing all of these actors into the same operation explains part of the strategic weight Venezuela is now acquiring.

In the end, interest in Venezuela is not reduced only to the potential of its reserves, or to the political decisions taken over them.

Its value arises precisely from those units that now need feedstock, from fuels, and from routes that have already stopped being reliable.
