Qatar Investment Authority, Qatar's state-owned holding company, invested $500m in Oryx Midstream Services, the largest privately-held midstream crude operator in the Permian Basin. QIA acquired a significant stake in Oryx from an affiliate of Stonepeak Infrastructure Partners. The CEO of QIA, Mansoor Al-Mahmoud, commented: "We believe that Oryx represents a strong midstream platform with tremendous growth potential, and we look forward to working with our new partners at Stonepeak. This acquisition is a further demonstration of QIA's strategy to increase the size of our US portfolio, and to invest more in major infrastructure projects."
