A Saudi Arabian oil official on Saturday refuted the conclusion of an analytics firm that the country's oil exports to the U.S. dramatically increased in the last month. TankerTrackers.com said on Thursday that Saudi Arabian oil exports to the U.S. more than doubled from February to March as oil prices crashed. The firm said its data indicates that the April export figure is on track to surpass March's number. An unnamed Saudi oil official who is familiar with the matter denied both conclusions. The official told CNBC that Saudi Arabia's April allocation for the United States is targeted at around 600,000 barrels per day, a figure which the official said is not a significant increase over the first-quarter monthly average. TankerTrackers, which uses satellite tracking of VLCCs — the vessels that transport crude — says that Saudi crude shipments to American ports went from an average of 366,000 barrels per day (bpd) in February to 829,540 bpd in March — a multiple of 2.27. TankerTrackers said that satellite tracking indicates 1.46 million barrels per day of Saudi oil shipped to the U.S. in the first two weeks of April — a figure that would mark four times February's daily volume and the highest figure since 2014. According to Saudi state oil producer Aramco's website, the company was loading 15 tankers for its international customers on April 1 — the day a previous OPEC production cut agreement with its oil-producing allies, OPEC+, expired — supplying the tankers with a record 18.8 million barrels in a single day.

The boost in exports comes against the backdrop of one of the most dramatic periods in oil market history: Record oil output from the world's largest oil producers juxtaposed with eviscerated demand due to worldwide coronavirus lockdowns as economic activity and global commercial transport came to a screeching halt. "Towards the end of March I saw massive boosts in gas flaring in the fields in the Eastern Province, so they went pedal to the metal and pumped out as much as possible," Samir Madani, founder of TankerTrackers.com, told CNBC over the phone Thursday. "It lit up like a Christmas tree, the whole Eastern Province, all the flares just came back online." Saudi Arabia's Eastern Province is home to the world's largest oil fields and processing facility, and the majority of the kingdom's production. Ahead of the April 1 expiration of the previous OPEC+ cutting deal, Saudi Arabia slashed its official selling prices (OSP) to its customers. At the same time, Saudi barrels headed to its top buyer, China, likely had to be re-routed due to China's extensive lockdown meant to combat the spread of the coronavirus in the country. "I am guessing that was in the immediate aftermath of the failed OPEC+ meeting at the beginning of March," Tamas Varga, an oil analyst at PVM Oil Associates, told CNBC. "That's when Saudis promised to increase production and exports significantly and cut OSP by several dollars."

In early March, negotiations between OPEC and its allies failed when Russia rejected Saudi Arabia's terms to cut production in order to boost prices, leading both states to reverse course and set off a price war, with the Saudis increasing production and slashing selling prices for its customers. The move was so destructive to oil markets — particularly the U.S. shale industry — that U.S. President Donald Trump called on the producers to rein in their output, though he did not do the same for U.S. shale companies, which are now seeing bankruptcies, capex cuts and production shut-ins due to market pressure. At the same time, China's demand for oil dropped significantly, as it kept its major economic hubs under lockdown and factories across the country of 1.4 billion remained closed. From February to March, Saudi oil shipments to China fell by nearly 800,000 bpd, picking up again to about 1.3 million bpd in the first half of April. "As the corona outbreak in China peaked in February, less crude import was contracted, and there is some weeks' lag between contracting and delivery," said Per Magnus Nysveen, head of analysis at Rystad Energy. "In the U.S. the refineries were still running full speed in March and some cargoes were therefore diverted to the U.S." Ellen Wald, president of Transversal Consulting and an expert on Saudi Aramco, added that this meant that "more oil was therefore available to ship to the U.S., where Aramco owns the largest refinery in the country," referring to the Motiva refinery in Port Arthur, Texas. For many American refineries, buying Saudi crude over American shale is also a matter of necessity — older refineries aren't designed to be able to process the lighter grade crudes coming from U.S. shale patches, and need medium and heavy grade crudes that Saudi Arabia produces, particularly for products like diesel.
