Project Description

The Iranian Central Oil Fields Company (ICOFC) has planned the complete design, procurement, construction, and commissioning of wellheads, gathering systems, and gas refinery plants for the Halegan & Sefid Baghoon gas fields.

Project Scope:

• Establish facilities to produce 20,000 MMSCMD of gas from 12 production wells.
• Export the produced gas to the IGAT-4 pipeline.
• Utilize Iranian companies’ knowledge and expertise for designing, procuring, and constructing the gas plant.

Consultant: Tehran Raymand has been selected for the pre-conceptual and feasibility study of this project.

Facilities of the National Gas Refinery

1. Well Head Facilities

• Initial processing and control at the wellheads.

2. Flow Lines

• 12 flow lines to transport gas from the wells to the processing facilities.

3. Manifolds

• 3 manifolds to combine the flow from multiple wells.

4. Reception Facilities

• Facilities for receiving gas from the wellheads and manifolds.

5. Gas Treatment (RIPI License)

• Processing to remove impurities and prepare gas for further processing.

6. Dehydration and Dew Point Control

• Removing moisture and controlling the dew point of the gas.

7. MEG Injection and Regeneration
