The Antrim Shale is a mature biogenic natural gas play known for its reliability and low decline production profile. Development of these assets began in the 1990s under previous operators, forming the foundation of one of Michigan’s most significant natural gas resource positions.

Since acquiring the assets in 2016, Riverside has expanded its footprint through strategic acquisitions including Riviera Resources, Inc. and Breitburn Operating, Inc., solidifying our position as Michigan’s leading natural gas producer.
