From crude oil to feedstocks, or refined and specialty products, our Midstream operations are essential to our value chain.

Our business is focused on three primary areas: crude oil and refined products, natural gas gathering and processing, NGL transportation and fractionation.

The integration of DCP Midstream, a major processor of natural gas and one of the largest U.S. producers and marketers of NGLs, bolsters Phillips 66’s already strong position in the latter.
