Project Description

The South Gashu gas field, located 70 km west of the port city of Bandar Abbas, comprises two producing reservoirs: “Khami” and “Sarvak,” with the Khami formation being the primary contributor to overall production. Recent reservoir studies predict a normal gas production of 500 MMSCFD from 20 wells.

Project Objective

The field will be developed to handle this production, with reservoir fluids transported via a network of flowlines and pipeline gathering systems to a processing plant. The processing will occur in two trains, with utilities, offsites, and necessary infrastructure established adjacent to the upstream and refinery process units.

The Iranian Central Oil Fields Company (ICOFC) has awarded the contract to Tehran Raymand Consulting Engineers for the Conceptual Design, Basic Engineering, and Front-End Engineering Design (FEED) of the upstream facilities, gas-processing plant, and off-plots. The goal is to process and transport gas to the Iran Gas Trunk Line – 7 (IGAT – 7) and export stabilized condensate and commercial sulfur.

Main Units and Facilities

Upstream Facilities:

• Wellhead Facilities: Infrastructure for controlling and managing the production from each well.
• Flow Lines: Pipelines to transport reservoir fluids from wells to gathering centers.
• Gathering and Separation Centers: Facilities to collect and separate gas, condensate, and water.
• Access Roads: Roads for transportation and access to various field facilities.
• Water Supply and Distribution Facilities: Systems for providing and distributing water for operations.
• Communication and SCADA System: Systems for monitoring, controlling, and data acquisition.

Downstream Facilities:

• Feed Receiving: Facilities for receiving reservoir fluids from upstream.
• Sweetening: Removal of hydrogen sulfide (H₂S) and carbon dioxide (CO₂) from the gas.
• Dehydration / HC Dew Point Control Process: Removing water and controlling hydrocarbon dew point.
