South Gashu Gas Field Development Project
The South Gashu Gas Field is an important energy project located approximately 70 kilometers west of Bandar Abbas in southern Iran. The field comprises two primary gas-producing reservoirs, known as the Khami and Sarvak formations. Among these, the Khami formation is recognized as the main source of production for this gas field.
According to recent reservoir engineering studies, the field is projected to deliver a normal gas production rate of 500 MMSCFD (million standard cubic feet per day) sourced from a total of 20 wells. The South Gashu development project aims to optimize extraction, processing, and export of natural gas and associated products, contributing to Iran’s energy infrastructure and export capability.
Project Objective and Development Scope
The development plan focuses on efficiently handling and processing the full production capacity of the field. Reservoir fluids will be gathered via an integrated network of flowlines and pipeline gathering systems, which transfer the fluids to a modern gas processing plant. Processing will be executed using two dedicated process trains, while utilities, offsites, and essential infrastructure will be established adjacent to both the upstream field and the refinery process units.
The Iranian Central Oil Fields Company (ICOFC) has awarded Tehran Raymand Consulting Engineers the contract for Conceptual Design, Basic Engineering, and Front-End Engineering Design (FEED) of the upstream facilities, gas processing plant, and associated off-plot areas. The project’s main objective is to process and transport natural gas to the Iran Gas Trunk Line – 7 (IGAT-7) and to export stabilized condensate and commercial-grade sulfur.
Main Units and Facilities
The South Gashu Gas Field Development project is divided into upstream and downstream facilities, each with specific roles:
-
