China's crude oil imports from Russia surged 52.4 percent in April from a year earlier to reach a record 1.17 million barrels per day (bpd), customs data showed on Monday, ahead of the previous record of 1.13 million bpd in December.

The Brent crude contract for July on London's ICE was up $1.14 to $48.97/bbl. The August contract gained $1.29 to $49.43/bbl. The June gas oil contract gained $11.50 to $430.25/tonne.

Perhaps the biggest hurdle is Russia’s business climate. While frequently fodder for criticism, there’s progress. Russia has surged by 61 spots in the World Bank’s Ease of Doing Business Index since 2013 to 51st this year.

The head of Russian oil major Lukoil said on Wednesday that he sees oil prices rising above $50 per barrel by the end of the year, RIA news agency reported, citing his TV interview.

The Paris-based agency said global oil stocks will experience a “dramatic reduction” in the second half of the year, but also warned that they will continue to increase in the first half of the year as Iran ramps up its production, adding to the nearly two years of oversupply.

Brent crude oil prices are forecast to average $41/b in 2016 and $51/b in 2017.

Nigeria's oil output fell close to a 22-year low this month due to attacks on oil pipelines in the southern Niger Delta, home to much of the country's oil and gas wealth, compounding the impact of low oil prices on Africa's largest economy.

After jumping more than 2% as the markets opened with Asian trading Sunday night, both major contracts fell as reports emerged that the threat from the fires was diminishing, at least for the moment.

Saudi Arabia, the world’s biggest oil exporter, plans “significant growth” in output in 2016 and further international expansion, the head of the country’s state-run producer said, even as global oversupply contributed to a drop in crude prices from a year ago.

Libya's production was down to 212,000 barrels on Monday, after the largest National Oil Corp (NOC) subsidiary, AGOCO, was forced to slash output by one-third from southeastern fields, an NOC spokesman in Tripoli said.

Light, sweet crude prices for June delivery varied widely on the New York market during Apr. 29 trading, closing at $45.92/bbl after swinging from a daily high of $46.78 and a low of $45.24.

“We still believe sustained front-month WTI at $45 to $50 will be self limiting, as U.S. shale-producer spending and drilling would stabilize and perhaps recover.”

US commercial crude oil inventories, excluding the Strategic Petroleum Reserve, increased 2.8 million bbl for the week ended Apr. 29 compared with the previous week. The US Energy Information Administration estimated a total of 543.4 million bbl, which is historically high for this time of year.

China’s falling oil output and sliding U.S. production may help rebalance a market struggling to recover from the worst price crash in a generation

The reality is that the Kremlin is always likely to be heavily involved in the Russian oil industry. That creates the concern that the proposals might be structured to try to achieve higher prices, which is not consistent with efficient price discovery.
