For years, the South Texas NGL market was a world of its own — a self-contained liquids ecosystem centered around the refineries and petrochemical plants in the Corpus Christi area. But that all changed about six years ago when EPIC Midstream built a new NGL pipeline from the Permian into Corpus and a new fractionator to process those liquids. Corpus morphed into a vibrant NGL market in its own right. But nothing with South Texas NGLs is easy. Before the EPIC system was even up and running, a consortium calling itself BANGL — short for Belvieu Alternative NGL — announced another pipeline to compete for Permian NGLs that would parallel EPIC’s route out of the Permian, but then make a hard left toward Sweeny and Texas City, setting up a battle of the pipes for Permian NGLs.
