The world’s biggest oil exporter, known as Saudi Aramco, won’t cancel any oil, gas or refining projects, Amin Nasser told reporters during a conference in Al-Ahsa in eastern Saudi Arabia. Aramco is also studying a possible expansion of the country’s largest oil refinery, Ras Tanura, which has a capacity of 550,000 barrels a day, he said Wednesday.

“The company continues to improve its efficiency responding to the challenges of the global market. In Q4 2015 upstream operating expenses per boe and maintenance expense of the Russian refinery in RUB terms slightly increased in comparison with Q4 2014, despite of the growth in industry prices by 10.7%. Increase in earnings before interests, tax and depreciation by 17.8% in 2015, in terms of significant decline in RUB and USD denominated oil prices show an effective control over operating costs that allowed the Company to reduce its debt burden considerably, significantly increasing the sustainability of the business in challenging macroeconomic environment”

China's total oil imports rose about 20 percent on year to the highest ever on a daily basis in February, when near 10-year low global oil prices drove buying from a group of new importers and for state and commercial stockpiling.

Saudi Aramco, through its wholly owned Saudi Refining Inc. (SRI), and Royal Dutch Shell, through its US downstream affiliate, agreed on Thursday to divide the assets of its 50:50 joint venture Motiva Enterprises.

Exploiting its proximity to northern Asia and the collapse of the rouble against the U.S. dollar, Russia has become the fastest growing oil supplier to Asia at a time when Middle East exporters are distracted by internal strife and competition from U.S. shale producers.

The world's biggest oil exporter lifted the official selling price (OSP) of its benchmark Arab Light crude by 25 cents a barrel for cargoes loading in April.

Oil was up from the start of the week after data showing a slide in shale crude output and strong gasoline demand in the United States. Also bolstering prices was a meeting scheduled for mid-March by at least four major oil producers, including Saudi Arabia, to discuss a production freeze at January's highs.

OPEC launched a price war against U.S. shale and other high-cost producers, including Canadian oil sands and Brazilian deep-water oilfields, in November 2014 by not reducing output despite a global oversupply. Since then, oil prices have plunged by more than half, hitting a 12-year low of about $26 on Feb. 11.

“We’ve worked out a common position,” Novak said, commenting on the deal. “We discussed various options, including doing nothing and cutting production.” An oil price at $50 a barrel is acceptable for exporters and consumers over the long term, he said. Brent crude, a global benchmark, traded at about $33 on Friday after dropping 45 percent over the past year.
