DALLAS–(BUSINESS WIRE)–Aspen Midstream, LLC (Aspen) today announced it has secured an equity commitment from EnCap Flatrock Midstream (EnCap Flatrock) and Aspen’s management team to launch Aspen Midstream II (Aspen II). Building on the proven track record of its veteran leadership team, the company will pursue midstream infrastructure opportunities across North America, primarily targeting natural gas transmission and last-mile solutions to support unprecedented gas demand growth.
Aspen II is led by founders and Co-Chief Executive Officers Matt Ray and Robert Underwood, along with Chief Commercial Officer Stephen Reilly. The executive team also includes Chief Financial Officer Blayne Dowell and Senior Vice President of Corporate Development Ben Kardell. In 2017, the team formed Aspen I, which today owns and operates a diverse midstream system that includes natural gas transmission, gas gathering, natural gas processing, CO₂ treating, and NGL transportation. This extensive system spans Fayette, Washington, Austin, Colorado, and Waller counties in the Austin Chalk formation of Texas.
“We are excited to once again partner with EnCap Flatrock Midstream, a trusted and valued partner for nearly a decade,” said Matt Ray, Co-CEO of Aspen Midstream. “We are confident in our ability to acquire assets and develop critical infrastructure that address the growing global demand for energy commodities such as natural gas.”

Aspen II’s extensive residue gas experience and deep commercial relationships positions the platform well for growth and value creation.”
