Forouz B Gas Field Development

MAPNA Oil and Gas Development Company, acting as the Buy Back Contractor for the Iranian Offshore Oil Company (Owner), has undertaken the development of the Forooz B gas field. The goal is to produce and treat 1000 MMSCFD of gas. The onshore facilities will be located on Qeshm Island, approximately 180 km from the offshore installations.

Purpose:

• Maximize the recovery of C3+ components
• Produce saleable products such as lean gas, propane, butane, natural gasoline, and sulfur
• Deliver lean gas at the battery limit

Project Scope

The project includes the design and construction of all processing units, utilities, offsite facilities, and necessary infrastructure to manufacture these products.

Project Responsibilities

Tehran Raymand’s Role:

• Conceptualization
• Basic design
• Front-end engineering design (FEED)
• Preparation of EPC tender documents
• Timeline: 12 months
