Name of Client: Saudi Aramco

Estimated Budget: $1,700,000,000

Contract Value: $1,850,000,000

Main Contractor: Samsung Engineering Company

Facility Type: Storage Tanks

Sector: Gas

Location: Hawiyah, Saudi Arabia

Award Date: 2020-Q1

Background

The purpose of the proposed Hawiyah Unayzah Gas Reservoir Storage Project is to provide the necessary facilities to store off-peak surplus sales gas via injection into the Hawiyah Unayzah reservoir during the low-demand season for reproduction back into the Master Gas System (MGS) during high demand; thereby maximizing the gas plants utilization. First of its kind gas storage project for Saudi Aramco, it includes a design compression facility for injecting 1500 million standard cubic feet per day (MMSCFD) and a design reproduction facility for reproducing 2000 MMSCFD of gas during peak consumption to produce sales quality gas. The project will enable Aramco to inject 1.5 bscfd of surplus natural gas from the MGS into the Hawiyah Unayzah Reservoir by 2022. In addition, the processing facilities will be able to reproduce up to 2.0 bscfd of gas stored for re-introduction into the MGS by 2024.

Project Status

As of August 2022, Samsung Engineering's work on the project is progressing accordingly to the schedule. The project is expected to be completed in 2024.

Project Scope

The project scope involves the construction of a gas injection facility which includes:

A design compression facility with an injection capacity of 1500 million standard cubic feet per day (MMSCFD)

A design reprocessing facility for reproducing 2000 MMSCFD of gas during peak consumption

Major equipment

Booster compressors

Injection compressors

Reproduction compressors

American Petroleum Institute (API) pumps and their drivers

A 380-kilovolt (kV) and 230-kV Bulk Supply Point (BSP) substation 752.5-Mega Volt Amp (MVA) power transformers and other equipment

Ten compression trains will be built for the injection portion of the plant, and another ten compression trains will be used for the reproduction portion of the plant.
