New EIA report about shale hydrocarbons published

The new report about estimated hydrocarbons in shale rocks has just been published by U.S. Energy Information Administration. It assesses 137 shale formations in 41 countries outside the US. In comparison to the previous report from 2011,  the number of analised formations has almost doubled, from 69!

There were two reasons for updating estimations of shale resources. Firstly, there are much more geologic research and well drilling results now (especially from Argentina, Mexico, China and Poland), than in 2011, so the assessments are more reliable. New report also includes shale formations which weren’t included in the previous report. Secondly, since 2011, recent developments in the United States have highlighted the role of shale formations and other tight plays as sources not only of natural gas, but also of crude oil or lease condensates.

New analysis couses an increase in World’s total resources of oil and gas for 11% and 47% respectively!

    TOP 5 countires with technically recoverable shale oil resources are: 1st Russia – 75 billion barrels, 2nd USA – 58 billion bbl, 3rd China – 32 billion bbl, 4th Argentina – 27 billion bbl and 5th Libya – 26 billion bbl.
    TOP 5 with technically recoverable shale gas resources: 1st China – 1 115 trillion cubic feet, 2nd Argentina – 802 trillion CF, 3rd Algeria – 707 trillion CF, 4th USA – 665 trillion CF, 5th Canada – 573 trillion CF.

There are a few notable changes in the reports from 2011 and 2013:

Poland’s shale gas resources estimation has decreased from 187 trillion CF to 148 trillion CF, according to data from drilled wells and geologic research. Similarly has happened to Norwegian, Chinese, South African and Mexican resources.
