Alaska's Cook Inlet Holds Significant Natural Gas Resources
A new assessment by the U.S. Geological Survey shows that the Cook Inlet Region of Alaska contains an estimated mean of 19 trillion cubic feet of natural gas, about 600 million barrels of oil, and 46 million barrels of natural gas liquids.
This estimate is of undiscovered, technically recoverable oil and gas resources, and includes both unconventional and conventional resources.
These gas estimates are significantly more than the last USGS assessment of southern Alaska in 1995, in which a mean of 2.14 trillion cubic feet of gas was estimated. This increase in the undiscovered resource is attributed to new geologic information and data.
"For the first time, USGS has evaluated unconventional (or continuous) as well as conventional petroleum resources in the Cook Inlet region of Alaska," said Brenda Pierce, USGS Energy Resources Program Coordinator.
Since oil and gas production began in the Cook Inlet region in 1958, more than 1.3 billion barrels of oil and 7.8 trillion cubic feet of gas have been produced, yet the new USGS assessment shows that significant undiscovered gas remains.
This USGS assessment includes estimates of conventional and unconventional, or continuous, accumulations, including coalbed gas and tight gas formations.
The USGS assessment of undiscovered gas resources ranges from 4.976 to 39.737 trillion cubic feet (95 percent and 5 percent probability, respectively. Of this total, about 72 percent is estimated to be found in conventional accumulations, 25 percent in coalbed gas accumulations, and 3 percent in tight gas accumulations.
