Rang Doi Gas Field

Summary Information

  • Operator: KNOC
  • Country: Vietnam
  • Location: Nam Con Son Basin about 320km offshore
  • Production start: 2006
  • Partners: PetroVietnam - 25%
  • Type: Gas
  • Estimated Reserves:
  • Production Volume: 165mscfd gas per day and 6000bbl condensate per day


  • The field consists of six wells; a wellhead platform; an 80 meters bridge; a production utilities quarters compression platform; gas and condensate pipelines, producing 165mscfd gas per day and 6000bbl condensate per day
