The New York Stock Exchange has delisted Gastar Exploration Inc. common and preferred stock after it failed to meet listing standards.

Gastar is a Midcontinent pure-play that works in the Anadarko Basin.

The Woodlands, TX-based Excelerate Energy LP and Argentina’s Transportadora de Gas del Sur SA (TGS) signed a memorandum of understanding to jointly study the technical and commercial viability of a liquefied natural gas export terminal at Bahia Blanca, Argentina, which would serve the country’s developing Vaca Muerta Shale in the Neuquén Basin. The study is expected to be completed by year’s end, at which time Excelerate and TGS would share the results with government and industry officials and decide on further actions.
