EIA has added four countries to its global assessment of technically recoverable shale oil and shale natural gas resources.
Chad, Kazakhstan, Oman, and the United Arab Emirates (UAE) have been added to a previous assessment covering 42 countries.
The move has boosted the assessed total resource estimate for shale oil by 13% and shale gas by 4%.
A total of 26 formations within 11 basins were analysed in four countries. The EIA said although the “formations contain significant volumes of technically recoverable resources”, there is currently no shale exploration underway in the four countries.
The economic recovery of the basins will depend on depend on crude oil and natural gas market prices, as well as the capital and operating costs and productivity within the countries, according to the EIA.
An EIA spokesperson said: “The resource estimates of these four countries, in addition to the other countries previously assessed in the 2013 EIA/ARI report on shale resources around the world, indicate proved and unproved technically recoverable resources of 419 billion barrels of shale oil resources and 7,576 trillion cubic feet of shale gas resources within 46 countries, including the United States. However, only four countries (the United States, Canada, China, and Argentina) are currently producing oil and natural gas from these resources at commercial scale, with the United States alone providing 4.4 million b/d, or more than 90%, of global tight oil production and 42 Bcf/d, or more than 89%, of global shale natural gas production.”
Chad’s oil production was 78,000 barrels per day (b/d) in 2014, down 55% since 2005. ad’s gross domestic product and provides the majority (63%) of government revenues.
Kazakhstan’s oil production increased by 24% to 1.7 million b/d from 2005 to 2014, while natural gas production increased 37% to 1.9 billion cubic feet per day (Bcf/d) over the same period.
Oman increased oil production by 18% to 943,000 b/d and natural gas production by 32% to 2.8 Bcf/d from 2005 to 2014.
The United Arab Emirates increased oil production by 21% to 3.7 million b/d and its natural gas production by 18% to 5.6 Bcf/d from 2005 to 2014. T
