Our Purpose

Advantage Midstream, based in Dallas, Texas, is a midstream and marketing company focused on applying advanced GTL conversion technology to produce premium liquid fuels from natural gas resources across North America. Advantage offers producers and processors tailored solutions for natural gas and natural gas liquids in areas that are geographically constrained or lacking proper infrastructure.

Gas-to-liquids (“GTL”) processing has been around for decades. As advancements in technology have allowed E&P companies to extract larger amounts of hydrocarbon deposits from our Earth’s minerals, the same can be said for the evolution in GTL solutions. 

Through our partnership with Greyrock Energy, Advantage will deploy proprietary Direct Fuel Production systems, unlike the older GTL processes, that can operate economically in significantly lower oil environments.
