Encana pleaded no contest on Monday to charges the company attempted to commit antitrust violations in Michigan in 2010.
The company agreed to pay a $5 million civil fine at a court hearing.
After Encana agreed to pay the fine, Michigan’s Attorney General dismissed a second criminal charge of antitrust violations against the company.
Michigan alleged that Encana and Chesapeake Energy conspired to keep oil and gas land lease prices artificially low during a 2010 leasing boom.
Encana’s plea of no contest followed internal investigations conducted by both companies.
The companies say the investigations showed no collusion was apparent in the sate of Michigan.
