He explained that the additional confirmed quantities "reached 15 trillion standard cubic feet of gas... and this achievement was achieved as a result of applying the highest international standards in estimating and developing hydrocarbon resources to ensure their proper exploitation."

Prince Abdulaziz bin Salman said in a statement published by the Saudi Press Agency that reserves in the Jafurah field are now estimated at approximately 229 trillion standard cubic feet of gas and 75 billion barrels of condensates.

Last August, China's Sinopec expressed its interest in participating in the Saudi-Jafurah shale gas project.

This comes in line with a previous report by Reuters, which stated that Sinopec and Total Energies were holding separate discussions with Saudi Aramco Oil Company to invest in the Jafurah project, which is the largest shale gas development project outside the United States, with reserves estimated at about 200 trillion cubic feet of raw gas.
