Saudi Arabia Natural Gas Reserves

Saudi Arabia holds proven natural gas reserves of approximately 333.8 trillion cubic feet (TCF), ranking sixth globally behind Russia, Iran, Qatar, the United States, and Turkmenistan. Despite this substantial resource base, the Kingdom has historically been a net gas importer due to surging domestic demand and the technical challenges of developing its unconventional gas resources. The Jafurah gas field development represents the centrepiece of Saudi Arabia’s strategy to become a major gas producer and potentially a net gas exporter.

Reserve Composition

Saudi Arabia’s gas reserves are classified into two categories. Associated gas, produced alongside crude oil, has been the primary source of domestic gas supply for decades. Non-associated gas, found in standalone reservoirs, represents the growth opportunity. Approximately 60 percent of the Kingdom’s gas reserves are associated with oil production, meaning gas output has historically been linked to, and constrained by, oil production decisions.

The challenge of relying on associated gas is that production levels are dictated by OPEC+ oil production targets rather than domestic gas demand. When Saudi Arabia cuts oil production, associated gas output also declines, creating potential domestic gas shortages even amid abundant reserves.

The Jafurah Basin

The Jafurah unconventional gas field, located in the Eastern Province south of Ghawar, is the most significant gas development in Saudi Arabia’s history. Covering an area of approximately 17,000 square kilometers, Jafurah contains an estimated 200 TCF of gas resources, making it one of the largest unconventional gas accumulations globally.

Saudi Aramco initiated the Jafurah development programme with plans to reach production of 2 billion standard cubic feet per day by 2027, scaling to 3.5 billion cubic feet per day by 2030. At full development, Jafurah alone could supply approximately one-third of the Kingdom’s total gas requirements.

The field produces both raw gas and significant quantities of natural gas liquids (NGLs) and condensate, which add economic value beyond the gas itself. The NGL output will feed into the Kingdom’s petrochemical industry, creating an integrated value chain from wellhead to manufactured products.

Domestic Gas Demand

Saudi Arabia’s domestic gas demand has grown steadily, driven by power generation, petrochemical feedstock, desalination, and industrial consumption. Total domestic gas consumption exceeds 10 billion standard cubic feet per day, making the Kingdom one of the largest gas consumers in the Middle East.

A key driver of gas demand growth has been the government’s policy to displace liquid fuels (crude oil and fuel oil) from power generation in favour of gas, freeing up more crude for export and reducing the carbon intensity of the power sector. The expansion of the petrochemical industry through SABIC, Saudi Aramco, and joint ventures has also increased gas feedstock demand.

Gas Pricing and Market Structure

Saudi Arabia does not export natural gas and maintains a regulated domestic gas price that has historically been below international market levels. The domestic price of methane gas is approximately USD 1.25 per million British thermal units (MMBtu), well below the global average. This subsidized pricing supports the competitiveness of the petrochemical industry and keeps electricity costs low.

Ethane, used as petrochemical feedstock, is priced at USD 1.75 per MMBtu. These regulated prices, while supporting industrial competitiveness, have also limited the economic incentive for new gas development, contributing to the slow pace of non-associated gas projects prior to the Jafurah initiative.

LNG Export Potential

Saudi Arabia has signaled interest in becoming an LNG exporter, a significant strategic shift from its historical position as a gas-deficit economy. If Jafurah production and other gas developments proceed as planned, the Kingdom could have surplus gas available for export by the late 2020s or early 2030s.

The potential entry of Saudi Arabia into the LNG export market would add a major new supplier to global gas trade and provide the Kingdom with a diversified hydrocarbon revenue stream beyond crude oil. However, the timing depends on the pace of domestic gas development, the trajectory of domestic demand, and commercial decisions about LNG infrastructure investment.

Other Gas Developments

Beyond Jafurah, Aramco is developing several other gas resources. The South Ghawar gas programme targets tight gas reservoirs beneath the southern section of the Ghawar oil field. The Haradh and Hawiyah gas compression projects maintain and enhance production from existing gas fields. Red Sea basin exploration has identified potential gas resources, though these remain at an early exploration stage.

Strategic Importance

Gas development serves multiple strategic objectives under Vision 2030. It reduces the domestic consumption of crude oil for power generation, freeing up approximately 1 million barrels per day for export or strategic reserve. It provides feedstock for the expanding petrochemical industry, supporting industrial diversification. It reduces the carbon intensity of the energy mix, supporting the Kingdom’s net-zero by 2060 commitment. And it potentially creates a new export revenue stream through LNG sales, further diversifying government income beyond crude oil.
