NuStar Energy LP‘s planned acquisition of natural gas liquids (NGL) pipeline and fractionation assets could be in jeopardy as seller TexStar Midstream Services LP told the company in mid-February that it was terminating the sale. NuStar disclosed during a midstream conference presentation in early March that it was evaluating its legal options in the matter. “If NuStar does not complete this acquisition, we do not expect a material adverse impact on our results of operations,” the company said in a presentation to a Morgan Stanley midstream conference. Last November, NuStar said it was buying the Eagle Ford Shale NGL assets, as well as Eagle Ford crude oil pipeline, gathering and storage assets (see Shale Daily, Nov. 9, 2012). The crude oil asset transaction, worth about $325 million, has closed. The pending NGL asset transaction is worth about $100 million.
