Oasis, Whiting Near All-Stock Merger

Oasis Petroleum Inc. and Whiting Petroleum Corp. are close to a deal to merge, according to people familiar with the matter.

The all-stock tie-up between the rival North Dakota shale drillers could be unveiled early this week, the people said, assuming the talks don’t fall apart. The companies combined would be worth roughly $6 billion, given Oasis’ market value of $2.8 billion and Whiting’s, which stands at $3.3 billion.
