Whiting Petroleum Corp,
North Dakota's
largest oil producer, posted a quarterly loss on Wednesday that more than doubled as production fell and crude prices dropped.
The company posted a second-quarter net loss of $301 million, or $1.33 per share, compared with a net loss of $149.3 million, or 73 cents per share, in the year-ago period.
