In 2012, the U.S. Geological Survey completed an assessment of undiscovered, technically recoverable oil and gas resources in three source rocks of the Alaska North Slope, including the lower part of the Jurassic to Lower Cretaceous Kingak Shale. In order to identify organic shale potential in the absence...

Located approximately 80 kilometers northwest of Anchorage, Alaska, the Susitna Basin is a complex sedimentary basin whose tectonic history has been poorly understood. Recent interpretation of two-dimensional seismic reflection data integrated with well, aeromagnetic, and gravity data provides new insights into the structural and stratigraphic nature of the basin.

A geologic model was developed for the assessment of potential Mesozoic tight-gas resources in the deep, central part of upper Cook Inlet Basin, south-central Alaska. The basic premise of the geologic model is that organic-bearing marine shales of the Middle Jurassic Tuxedni Group achieved adequate thermal maturity for oil and gas generation in the central part of the basin largely due to several kilometers of Paleogene and Neogene burial.

Current estimates of discovered viscous and heavy oil in Alaska’s North Slope are 12 billion barrels of oil-in-place and 12–18 billion barrels of oil-in-place, respectively (see Appendix 1 for conversion to SI units). Since the early 1990s to the end of 2010, cumulative viscous oil production has amounted to 150 million barrels, and there has been no commercial production of heavy oil...

Chapter I - This report presents fourteen storage assessment units (SAUs) from the Alaska North Slope and two SAUs from the Kandik Basin of Alaska. The Alaska North Slope is a broad, north-dipping coastal plain that is underlain by a thick succession of sedimentary rocks that accumulated steadily throughout much of the Phanerozoic during three major tectonic sequences: the Mississippian through Triassic Ellesmerian sequence, the Jurassic through Lower Cretaceous Beaufortian sequence, and the Cretaceous and Tertiary Brookian sequence.

The U.S. Geological Survey, in partnership with the U.S. Bureau of Land Management, the North Slope Borough, and the Arctic Slope Regional Corporation conducted a four-year study designed to identify, define, and delineate a shallow coalbed natural gas (CBNG) resource with the potential to provide locally produced, affordable power to the community of Wainwright, Alaska.

USGS Publication: Digital Data Series DDS–69–CCScientists with the U.S. Geological Survey have completed the first assessment of the undiscovered, technically recoverable gas hydrate resources beneath the North Slope of Alaska. This assessment indicates the existence of technically recoverable gas hydrate resources—that is, resources that can be discovered, developed, and produced using current technology.

Press Release & Publication
Akutan Volcano hosts a geothermal system that includes a fumarole field at about 400 meters (1312 feet) elevation on the northeast flank of the volcano and a series of hot springs that discharge close to sea level on the northeast side of the island. Numerous industry-led geophysical studies and test drilling in the past few years have proven the existence of a geothermal resource. USGS field studies completed in 2012 suggest that the available geothermal resource may be even larger than previously recognized.

We used Rock-Eval pyrolysis and vitrinite reflectance to examine the petroleum source potential of rock samples from the Sheep Creek 1 well in the Susitna basin of south-central Alaska. The results show that Miocene nonmarine coal, carbonaceous shale, and mudstone are potential sources of hydrocarbons and are thermally immature with respect to the oil window.
There are several energy-related efforts currently under way in Alaska. Geographically, these range from the Alaska Peninsula to the North Slope. Several are collaborative efforts with Federal and State agencies and Alaska Native villages. These projects:
Alaska’s scenic wilderness, its Arctic ecosystems with their unique flora and fauna, and its significant potential for energy and mineral resources are unmatched by any other onshore region of the U.S. Thus, the accurate and unbiased scientific data provided by the U.S. Geological Survey are crucial to the Federal, State, and Native organizations that manage Alaska’s resources to meet the challenge of balancing America’s needs for nonrenewable resources and a clean and healthy environment.
Current work focused on assessment of the area west of NPRA and aggregation of all North Slope assessments with an update of the economics, including natural gas.
The 2010 assessment supersede those of a previous assessment completed by the USGS in 2002.

The “1002 area” is a 1.5-million-acre part of the coastal plain that holds potentially large oil and gas resources, and is an important wildlife habitat. In recognition of these facts, a decision regarding whether this area should be opened to petroleum exploration has been deferred since the establishment of the Arctic National Wildlife...
In 2005 the U.S. Geological Survey (USGS) completed an assessment of undiscovered oil and gas resources of the central Alaska North Slope and the adjacent offshore belonging to the State of Alaska. This area lies between the Arctic National Wildlife Refuge (ANWR) and extends from the Brooks Range northward to the State-Federal... [+]

In 2008 USGS completed the first assessment of the undiscovered technically recoverable gashydrate resources on the North Slope of Alaska. Using a geologybased assessment methodology, the USGS estimates that there are about 85 trillion cubic feet (TCF) of undiscovered, technically recoverable gas resources within gas hydrates in northern Alaska.

Compilation of existing geologic maps of the northern foothills of the Brooks Range, from the Chukchi Sea eastward to the Canadian border. This work is a collaboration between the USGS and the Alaska Department of Natural Resources, Division of Geological and Geophysical Surveys (DGGS) and the Division of Oil and Gas.
The National Petroleum Reserve, Alaska, (NPRA) Legacy Data Archive represents one of the largest geological and geophysical data sets held by the U.S. Geological Survey (USGS). From 1944 to 1953 the U.S. Navy operated a large-scale exploration of the then Naval Petroleum Reserve No. 4, drilling 36 test wells and 45 core tests. A second extensive exploration program was operated between 1974 and 1982...

Alaska related U.S. Geological Survey publications. The collection is not complete but includes historical and pertinent documents published prior to 2002. This collection of historical publications includes, USGS Professional Paper 20, the first systematic topographic and geologic survey across the Brooks Range and the North Slope published in 1901 by F.C. Schrader (USGS geologist) with notes by W.J. Peters (USGS topographer). "Schrader described thick marine sequences and noted broad anticlinal structures--both of prime importance in the search for oil.” (USGS Prof. Paper 1240-C).
