As OPEC’s efforts to balance the oil market bear fruit, U.S. producers are reaping the benefits – and flooding Europe with a record amount of crude, Reuters reports.

Russia paired with the Organization of the Petroleum Exporting Countries last year in cutting oil output jointly by 1.8 million barrels per day (bpd), a deal they say has largely rebalanced the market and one that has helped elevate benchmark Brent prices close to four-year highs. But now, the relatively high prices brought about by that pact, coupled with surging U.S. output, are making it harder to sell Russian, Nigerian and other oil grades in Europe, traders said.

U.S. oil output is expected to hit 10.7 million bpd this year, rivaling that of top producers Russia and Saudi Arabia. In April, U.S. supplies to Europe are set to reach an all-time high of roughly 550,000 bpd (around 2.2 million tonnes), according to the Thomson Reuters Eikon trade flows monitor. Trade sources said U.S. flows to Europe would keep rising, with U.S. barrels increasingly finding homes in foreign refineries, often at the expense of oil from OPEC or Russia.
