The Explorer pipeline is one of the major refined product pipelines that moves gasoline, diesel, and jet fuel from the US Gulf Coast to the US Midwest market

Historically Explorer has been an important source of supply for the Midwest region, but as local refining production in the Midwest has increased the need for movements on Explorer has declined.

Due to the volume of product moved, the pipeline (especially at its Houston origin) is a major point for spot trading of these products, providing the Gulf Coast Pipe price assessment.
