Oman LNG was structured and set up to manage and operate the "Downstream" of Oman's gas operations, involving mainly the liquefaction, transportation and respective sales of the produced liquefied natural gas (LNG). Whilst the "Upstream" is fully government owned and operated by Petroleum Development Oman. The upstream processes involve the field appraisal and development, gas processing and transport by pipeline to the liquefaction plant.[1][6]
