TEHRAN — The gas storage capacity at the Sarajeh field will increase to 1.5 billion cubic meters (bcm) per year, with daily extraction rising to 15 million cubic meters, upon completion of its second development phase. This expansion will strengthen Iran’s gas network resilience during peak winter demand.
The Sarajeh gas field, Iran’s first underground natural gas storage facility, began operations in 2015 to support the national gas grid during high-consumption periods. Located in Iran’s central desert with unique geological features, it currently stores 1 billion cubic meters of gas annually and extracts 10 million cubic meters per day, using optimized infrastructure and domestic technology.
The second-phase development project, launched in 2022 and 2023 in upstream and downstream sections, aims to enhance gas network stability and winter peak-shaving. Once completed by year-end 2024, storage capacity will reach 1.5 billion cubic meters, with daily extraction peaking at 15 million cubic meters. Due to its proximity to other storage projects like Nasrabad and Shourab, Sarajeh is poised to become a regional gas storage hub. Economically, it remains one of the most cost-effective storage methods globally.
Saeid Rajabzadeh, head of gas storage projects at the Iran Gas Engineering and Development Company (IGEDC), noted that the Sarajeh field was discovered in 1959, located 130 kilometers south of Tehran. Sixteen wells have been drilled so far, with the first development phase converting it into a storage facility starting in 2005. Full operation began in 2015, allowing 1 billion cubic meters of gas injection during warm months and up to 10 million cubic meters of daily extraction in winter, depending on climate conditions.
He explained the injection-extraction cycle: Gas is injected from the national grid into Sarajeh during eight warm months, then extracted and redistributed during four cold months.
