Siemens Energy (Siemens) will provide centrifugal compressor systems for Saudi Aramco’s Hawiyah Unayzah Gas Reservoir Storage (HUGRS) project. The plant includes a gas injection facility with a capacity of 1,500 MMSCFD (42.4 x 106 m3/d) and a withdrawal facility capable of processing up to 2,000 MMSCFD (566 x 106 m3/d) of gas.
Siemens Energy received the order from Samsung Engineering (Samsung), which was awarded the engineering, procurement, and construction contract earlier this year. Samsung’s scope of work includes gas injection facility with booster compressors and injection compressors, gas reproduction facility with reproduction compressors, and slug catchers as well as utilities and offsite facilities.
The project, located 162 miles (260 km) east of Saudi Arabia’s capital, Riyadh, includes a plant that will take surplus pipelines gas in the winter months and inject it into an existing depleted field. From there, it can be withdrawn when needed to meet high summer demand.
Siemens will supply the required 20 compression trains. Ten trains will be built for the injection portion of the plant, and another 10 trains will be used for the withdrawal portion of the plant.
