South Pars Gas Field Development Project – Phase 17 & 18
The South Pars Gas Field Development Project – Phases 17 & 18 is a major initiative to boost Iran’s natural gas production and export capacity in the Persian Gulf region. The IDRO/OIEC/IOEC Consortium has been contracted by the National Iranian Oil Company (NIOC) to deliver a full EPCC (Engineering, Procurement, Construction, and Commissioning) package for these strategic phases.
This comprehensive project covers the development and operation of offshore platforms, undersea pipelines, and large onshore processing plants. Its goal is the efficient processing of reservoir fluids, converting raw gas into high-quality sales gas and stabilized condensate for domestic supply and international export.
Key Project Participants
-
IDRO/OIEC/IOEC Consortium: Main contractor responsible for the full EPCC scope, managing project execution from engineering to commissioning.
-
Worley Parson Pty Ltd: Providing basic engineering and FEED (Front-End Engineering Design) for all onshore facilities.
-
Tehran Raymand Consulting Engineers: In charge of detailed engineering design for critical onshore units in Phases 17 & 18, under contract with Petro Negin Jonoob (PNJC).
Project Capacity and Product Output
-
Total Capacity: The onshore facilities are designed to process 2,000 MMSCFD (million standard cubic feet per day) of reservoir fluid from the South Pars field.
-
Output: Production of high-quality sales gas and stabilized condensate to support Iran’s energy market and export commitments.
