Gas Drives Increase in USGS Global Resource Estimate

摘要

A meaningful shift has taken place in the world's undiscovered conventional oil and gas resources since 2000, with the US Geological Survey (USGS) estimating a sharp uptick in non-US gas resources which has helped to offset a decline in oil resources. According to the USGS, some 171 geologic provinces outside the US hold a mean 565 billion barrels of undiscovered, technically recoverable conventional oil, 5,606 trillion cubic feet (934 billion boe) of natural gas and 167 billion barrels of natural gas liquids (NGLs).
