Hasbah

Hasbah Gas Field Profile

Location and Geology

The Hasbah gas field is located offshore in the Arabian Gulf, approximately 150km north-east of Jubail, Saudi Arabia. It is part of the Hasbah/Arabiyah complex in the Eastern Province of Saudi Arabia.

Operator and Ownership

The field is operated and owned by Saudi Aramco.

Discovery and Production

The Hasbah gas field was discovered in 2008. The first gas production from the field began in March 2016.

Field Development

• The initial development of the Hasbah field included seven production wells designed to resist 10,000 pounds per square inch (psi) of pressure. These wells are part of seven gas wellhead platforms with a production capacity of 350 million standard cubic feet per day (Mscfd).
• The gas produced is transported to tie-in platforms and then exported to the Wasit gas plant through a 36-inch diameter pipeline.

Expansion Project

The Hasbah gas field is undergoing an expansion known as the Hasbah offshore gas facilities increment II. Key aspects of this expansion include:

• Drilling of four new production wells.
• Installation of six wellhead platforms, along with six topsides and two jackets, each weighing 1,900 tons.
• Installation of two tie-in float-over platforms, each weighing 6,700 tons.
• Laying of offshore pipelines, including two 36-inch diameter pipelines (one 120km long with a 1.9km CRA section, and another 126km long with a 2.8km CRA section) to export gas to the Fadhili gas plant for processing.
• Installation of three 110km-long subsea cables for power and communication.
• Subsea umbilicals, risers and flowlines (SURF) including various pipelines and integrated service umbilicals.

Contractors Involved

• The engineering, procurement, installation, and commissioning (EPCI) contract for the expansion project was awarded to a consortium of Larsen & Toubro Hydrocarbon Engineering (LTHE) and Subsea 7, under a long-term agreement worth more than $1.6 billion.
• McDermott won an EPCI contract for a wellhead production deck module, a flowline, and a subsea umbilical cable.
• Other contractors include Functional Safety Engineering Services (FSES) for safety studies, ZTT Group for subsea cables, BEL Valves, Glacier Energy Services, and TECNOVA Group.

Production and Reserves

• The current production capacity of the Hasbah field is 350 Mscfd from the initial seven wells.
• The expansion project aims to add up to 2.5 billion standard cubic feet per day (scfd) of non-associated gas to the production.
• As of 2021, the remaining gas reserves at the Hasbah field are estimated to be approximately 577 million cubic meters.

Infrastructure and Facilities

• The gas produced from the field is processed at the Wasit Gas Plant.
• The field includes wellhead platforms, tie-in platforms, and offshore pipelines. The expansion adds new platforms, pipelines, and subsea infrastructure to support increased production.

Economic and Social Impact

• The project provides significant job opportunities for Saudis and helps in elevating the skills of a new generation of employees.
• The development of the Hasbah field is part of Saudi Aramco’s strategy to increase domestic gas supplies, aiming to nearly double gas production to over 20 Bscfd in the next decade. This will help in using gas for domestic power generation, reducing environmental pollution, and supporting the local economy.

Environmental Considerations

• While the project does not specifically highlight environmental measures, Saudi Aramco's overall strategy includes reducing environmental impact by increasing the use of cleaner-burning gas for power generation.

In summary, the Hasbah gas field is a critical component of Saudi Aramco's efforts to meet the rising domestic energy demands of Saudi Arabia, with significant investments in infrastructure, technology, and workforce development.
