Saudi Aramco, the world’s largest oil exporter, is set to join the shale revolution with plans to start producing unconventional natural gas this month and exploit a deposit that could rival the Eagle Ford formation in Texas.
Saudi Arabia’s gas resources from shale and other alternative supplies are “huge,” Khalid Al Abdulqader, general manager of unconventional resources at Aramco, said Wednesday in Manama, Bahrain. Production at the kingdom’s North Arabia basin will start by the end of March and reach its target by the end of this year, he said, without giving details.
Aramco is also drilling for unconventional gas in the South Ghawar and Jafurah basins, he said. Jafurah in eastern Saudi Arabia is similar in size to Eagle Ford, the second-biggest US shale play for gas, Al Abdulqader said, without giving an estimate of the gas contained at Jafurah.
“It’s completely believable,” Robin Mills, chief executive of Dubai-based consultant Qamar Energy, said of the comparison. “Can they make a commercial proposition of it? That’s the question.”
State-run Aramco, formally known as Saudi Arabian Oil Company, plans to spend $300 billion on projects over the next 10 years to maintain its spare production capacity for oil and boost exploration for and output of conventional and unconventional gas, chief executive Amin Nasser said in July. Any increase in supplies of gas drilled from shale and other hard-to-access rocks would free up crude that Saudi Arabia uses in its power plants, enabling the country to export the oil for a bigger profit.

Eagle Ford in Texas had 22.7 trillion cubic feet of natural gas reserves from shale in 2016, according to a US Energy Information Administration report in February. Aramco plans to double its production of gas resources to 23 billion cubic feet a day over the coming decade, Nasser said.
Jafurah is located between Ghawar, the world’s largest oilfield, and the Arabian Gulf, near the hub of the Saudi energy industry. Pipeline networks and other facilities needed for Aramco to produce unconventional gas at Jafurah are nearby, and this existing infrastructure should help expedite the basin’s development, Mills said.
Aramco plans to develop the entire basin, using improved technology to reduce fracking costs, Al Abdulqader said. The company will focus on cutting costs at Jafurah before proceeding with plans to produce gas there, he said.
Saudi Arabia traditionally pumped gas only as a by-product of crude. The nation began its hunt for gas in the early 2000s after oil sank below $10 a barrel and unemployment worsened. It invited Exxon Mobil, Chevron and others in the hope of attracting $100bn of investment. Many pulled out following years of talks, and dry holes forced Total, Eni and Repsol to exit ventures with Aramco.
Lukoil, one of Aramco’s last remaining partners in a gas exploration venture, planned to leave the project in the kingdom’s Empty Quarter desert after finding no commercially viable deposits of the fuel, Gati Al Jebouri, Lukoil’s head of upstream for the Middle East, said in January 2017 in Dubai.
