New York/Houston | The US shale oil industry faces a barrage of lawsuits alleging some of the largest companies in the sector colluded to curb output and raise prices, after similar claims were made by US antitrust regulators.
ExxonMobil, Occidental Petroleum and Diamondback Energy are among the companies named in at least 10 class actions alleging they conspired to co-ordinate and constrain shale oil production, which had the effect of raising US retail petrol prices.
