Riverstone Holdings and Vista Oil & Gas to invest $205m in Aleph Midstream.

Private equity firm Riverstone Holdings and Vista Oil & Gas, a Mexico-based company engaged in the energy sector, agreed to invest $205m in Aleph Midstream, an independent Argentine oil and gas gathering and processing-focused midstream company. "The growth of production of oil and gas from the Vaca Muerta shale formation in Argentina has created a need for gathering, processing and evacuation midstream investments, as well as potential needs for oil and gas storage, condensates handling and additional oil and gas trunk pipeline capacity. By providing midstream services, Aleph Midstream could allow upstream players to focus on their core E&P activities," Vista Oil & Gas.
