Continental Resources Inc (CLR.N), North Dakota’s second-largest oil producer, said on Tuesday it would slash its 2016 capital budget by 66 percent as it tries to preserve cash amid tumbling crude prices. Led by billionaire wildcatter Harold Hamm, Continental plans to spend $920 million this year, down from $2.7 billion in 2015. The cut comes just after rival Hess Corp (HES.N) and Noble Energy Inc (NBL.N) slashed their own 2016 budgets, adding to a chorus of company executives chanting that the plunge in oil prices has made it all but impossible to turn a profit.
