Yesterday MarkWest Liberty NGL Pipeline, a subsidiary/part of MarkWest Energy (now MPLX since being bought out and merged into Marathon Petroleum in late 2015), announced plans to build a new NGL pipeline. MarkWest Liberty launched a binding open season for the new pipeline–a time when drillers can sign on the dotted line to reserve capacity along the new pipeline. The new NGL pipeline is a bit different than other NGL pipelines in the Marcellus/Utica. It will pick up NGLs from several of MarkWest’s gas processing plants in Pennsylvania and West Virginia, and cart the NGLs to fractionation facilities owned by MarkWest in PA and Ohio, where those NGLs will get separated into their discrete hydrocarbon components. Let us explain it this way: Step One is that the gas comes out of the ground. But it’s not all just methane–there’s a number of other hydrocarbons (natural gas liquids, or NGLs) mixed in with it, things like ethane, butane, propane, pentane. The raw mix goes to a cryogenic processing plant where the methane (i.e. natural gas) is separated out and sent on its way to market via pipelines like Rover and Rockies Express and others. Step Two: The NGLs need further separating. That’s what a fractionation plant does. This new pipeline from MarkWest Liberty (the Marcellus unit of MarkWest) will cart the mixed bag of NGLs to fractionation facilities. After being separated into component parts, the components can then be sold. Which fits with MarkWest’s prior statements that in 2018 they would focus on creating new markets for Marcellus/Utica NGLs, butane in particular (see MarkWest Building 6 New Processing Plants, 3 Fractionators in 2018). So, which processing plants will the pipeline connect to, and which fractionation plants? The announcement does not say, and there is no PDF document available with the details, at least not publicly. For that, you need to contact MarkWest directly. We do, however, have a map of MarkWest’s facilities…
