South Pars Gas Field Development – Phases 20 & 21

Development of South Pars phases 20 & 21 was awarded to OIEC both in onshore and offshore to produce 2MMMSCFD of natural gas by drilling 24 wells, installing 2 unmanned wellhead platforms and transferring the fluids to onshore refinery by two 32” subsea pipelines. The onshore facilities were developed on the basis of supplying treated lean gas to domestic network and ethane gas to nearby petrochemical complexes, LPG (propane and butane) for export and condensate for both export and domestic use.
South Pars phases 20 & 21 was a significant mega gas project and OIEC Group gained exceptional experiences through designing, constructing and managing such project in onshore and offshore, upstream and downstream.
