At least 34 U.S.-sanctioned oil tankers with a history of carrying Venezuelan oil are currently at sea in the Caribbean, according to a new analysis obtained by CNBC on Wednesday.
And at least 12 of those tankers appear to be filled with crude oil from Venezuela, according to vessel location data from Kpler, a global trade intelligence company.
One of the tankers, Skipper, was seized by the U.S. forces in the Caribbean last week and was being taken to the United States.
Kpler provided the analysis a day after President Donald Trump vowed to impose a “complete and total blockade” on sanctioned oil tankers moving in and out of Venezuela. Trump also deemed the nation’s ruling Maduro regime a foreign terrorist organization.
The U.S. is expected to block only sanctioned tankers carrying oil from Venezuela, not similar vessels that have other nations’ crude, including oil from Iran and Russia, according to Kpler.
“In light of President Trump’s recent announcement, these tankers may be exposed to heightened scrutiny and potential enforcement actions by U.S. authorities,” Dimitris Ampatzidis, senior risk and compliance Analyst at Kpler, told CNBC.
In a separate report to clients on Wednesday, Kpler said that a blockade of Venezuelan oil should not lead to higher crude prices.

“The move has so far failed to provide a meaningful boost to oil prices or to overturn underlying fundamentals, largely because the market is two-tiered and even the sanctioned segment remains crowded,” Kpler’s report said.
Oil prices rallied by nearly 2% on Wednesday.
Chevron is the only company authorised by the United States to carry Venezuelan crude to the U.S.
“Oil bound for the US under Chevron’s license could continue to flow,” Kpler’s report said.
“This suggests that Venezuelan supply to sanctioned markets would be disrupted, while volumes destined for the US would remain intact, with China- and Cuba-bound cargoes bearing the brunt of the impact.”
Besides Skipper, the 11 sanctioned tankers that appear to be carrying Venezuelan crude are Star Twinkle 6, Hyperion, Boceanica, Lydya N, Sensus, Soldier, Avril, Phenix VI, Manuela Saenz, Dianchi, and Yi Meng Shan.

Venezuela has produced around 900,000 barrels of crude oil and condensate so far in 2025, accounting for roughly 1% of the total global supply.
Kpler data indicates China buys about 76 percent of Venezuela’s output.
The U.S. has imported around 17% of Venezuela’s output in 2025. That is about half of the percentage of output imported in 2024.
Cuba, Spain, and Italy are the other significant customers of Venezuela’s oil.
“Cargoes bound for the US are expected to remain intact, while China and Cuba are likely to seek substitutes from Russia and Iran,” Kpler’s report noted.
