Late Cretaceous-Cenozoic exhumation of the western Brooks Range, Alaska, revealed from apatite and zircon fission track data
We report data for 112 apatite and 31 zircon fission track (AFT and ZFT) outcrop sandstone samples along a transect that spans the western Brooks Range. Sampling targeted structures that modify the Middle Jurassic‐Early Cretaceous early Brookian orogen. The AFT samples record latest Cretaceous to Eocene in situ exhumational cooling and resolve two kinematic phases. The first phase was focused at 6

Understanding the captivity effect on invertebrate communities transplanted into an experimental stream laboratory
Little is known about how design and testing methodologies affect the macroinvertebrate communities that are held captive in mesocosms. To address this knowledge gap, we conducted a 32‐d test to determine how seeded invertebrate communities changed once removed from the natural stream and introduced to the laboratory. We evaluated larvae survival and adult emergence in controls from 4 subsequent s

Geology and assessment of undiscovered oil and gas resources of the Northern West Siberian Mesozoic Composite Total Petroleum System of the West Siberian Basin Province, Russia, 2008
The West Siberian Basin Province is one of the largest sedimentary basins in the world, with an area of 2.6 million square kilometers, and the basin ranks first in the world with more than 400 billion barrels of oil-equivalent discovered petroleum. For the 2008 Circum-Arctic Resource Appraisal, the U.S. Geological Survey defined a Northern West Siberian Mesozoic Composite Total Petroleum System (T

Methodology for correcting bottomhole temperatures acquired from wireline logging measurements in the onshore U.S. Gulf of Mexico Basin to characterize the thermal regime of total petroleum systems
Characterization of the subsurface thermal regime is critical for understanding many facets of the petroleum system, from thermal maturation of organic-rich source rocks to thermal preservation and non-degradation of hydrocarbon accumulations. On a broad scale, paleo-heatflow has been mapped for the North American continent (Blackwell and Richards, 2004) as well as the contiguous United States (Bl

Statistical detection of flow regime changes in horizontal hydraulically fractured Bakken oil wells
The application of horizontal and hydraulically fractured wells for producing oil from low permeability formations has changed the face of the North American oil industry. One feature of the production profile of many such wells is a transition from transient linear oil flow to boundary-dominated flow. The identification of the time of this transition is important for the calibration of models tha

Distinguishing brackish lacustrine from brackish marine deposits in the stratigraphic record: A case study from the late Miocene and early Pliocene Bouse Formation, Arizona and California, USA
Brackish marine and brackish continental environments are fundamentally different from a compositional perspective. Brackish water is often defined as having salinity lower than that of standard seawater but higher than that of freshwater, but less regard is given to the origin of the salts involved. The simple dilution of standard seawater by freshwater in a coastal or estuarine setting constitut

Paleoseismic results from the Alpine site, Wasatch fault zone: Timing and displacement data for six holocene earthquakes at the Salt Lake City–Provo segment boundary
To improve the characterization of Holocene earthquakes on the Wasatch fault zone (WFZ), we conducted light detection and ranging (lidar)‐based neotectonic mapping and excavated a paleoseismic trench across an 8‐m‐high fault scarp near Alpine, Utah, located <1 km<1 km south of the boundary between the Salt Lake City and Provo segments (SLCS and PS). We document evidence for six paleoearthquakes

Geology and assessment of undiscovered oil and gas resources of the Tunguska Basin Province, 2008
The U.S. Geological Survey has evaluated the potential for undiscovered oil and gas resources of the Tunguska Basin Province as part of the Circum-Arctic Resource Appraisal (CARA). The Tunguska Basin Province includes an area of approximately 904,000 km2; less than half the area of the province lies north of the Arctic Circle. The Tunguska Basin Province includes a large part of the Siberian crato

Estimating the pressure-limited CO2 injection and storage capacity of the United States saline formations: Effect of the presence of hydrocarbon reservoirs
The U.S. Geological Survey (USGS) national assessment of carbon dioxide (CO2) storage capacity evaluated 192 saline Storage Assessment Units (SAUs) in 33 U.S. onshore sedimentary basins that may be utilized for CO2 storage (see USGS Circular 1386). Similar to many other available models, volumetric analysis was utilized to estimate the initial CO2injection and storage capacity of these SAUs based

Geology and assessment of undiscovered oil and gas resources of the Lena-Anabar Basin Province, 2008
The U.S. Geological Survey (USGS) assessed the potential for undiscovered oil and gas resources of the Lena-Anabar Basin Province as part of its Circum-Arctic Resource Appraisal program. The province is in the Russian High Arctic and is located between the Laptev Sea and the Siberian craton. Three assessment units (AUs) were defined for this study—the Lena-Anabar Basin AU, the Lena-Anabar Basin Up

Geology and assessment of undiscovered oil and gas resources of the Mezen’ Basin Province, 2008
The Mezen’ Basin Province is situated along the White and Barents Seas in the northeastern part of the Russian Federation. Only a small area of the province, part of one graben, extends slightly north of the Arctic Circle onto the Kanin-Kola monocline, where it converges with the Timan-Varanger deformed belt and the Fennoscandian shield.The main petroleum potential in the Mezen’ Basin Province is

Material balance approach for determining oil saturation at the start of carbon dioxide enhanced oil recovery
Oil producers have been using enhanced oil recovery methods, including (1) thermal recovery for heavy oil and (2) carbon dioxide enhanced oil recovery (CO2-EOR) for medium or light oil, to maximize oil recovery from existing reservoirs. The CO2-EOR method is widely used for recovering additional oil after waterflood, which leaves behind a large volume of oil in the reservoir. Completing a CO2-EOR
