Role in the system
What this sector controls
Midstream companies make location matter. Their physical networks collect, condition, transport, store, and deliver hydrocarbons, creating the capacity constraints and market connections behind many regional price differences.
Use this sector to identify infrastructure owners by commodity, asset type, corridor, geography, and the upstream, downstream, utility, or export markets their systems connect.
