Filled oil drums are seen at Royal Dutch Shell Plc’s lubricants blending plant in the town of Torzhok, north-west of Tver, November 7, 2014. Royal Dutch Shell is currently offering 16 assets worth more than $500 million for sale as part of its vast $30 billion three-year asset sales program, the oil and gas company’s head of upstream Andy Brown said on Wednesday. The Anglo-Dutch company launched the program to reduce its debt following the acquisition of BG Group earlier this year. Uncertainty over the future oil price has led to a sharp slowdown in deal making in the sector in recent years. “There are 16 assets currently in the market that are above $500 million in value,” Brown told the Oil and Money conference in London.
