Hildestad, president and chief executive officer of MDU Resources. “With five rigs now running in the Bakken and this recent development in the Paradox, the prospect of significant and sustainable oil growth over the coming years looks very encouraging.”Forward-Looking Statements The information in this release includes certain forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934.
