Naturally occurring hydrocarbons, typically fluid or gas, often of economic use. Includes oil, natural gas, and asphaltic compounds found in tar sands and oil shales.
Computer simulation of reservoir depletion and oil flow from the Macondo well following the Deepwater Horizon blowout [ More info] This model estimates, by simulation, the reservoir pressure, flow rate, and volume of oil discharged, and the report discusses the uncertainty in the estimates.
Effects of Building a Sand Barrier Berm to Mitigate the Effects of the Deepwater Horizon Oil Spill on Louisiana Marshes [ More info] An assessment of the potential protective effects on coastal marshes in Louisiana of building barrier berms seaward of the existing barrier islands and inlets to help block or reduce the onshore spread of oil from the Deepwater Horizon oil spill.
In-place oil shale resources examined by grade in the major basins of the Green River Formation, Colorado, Utah, and Wyoming [ More info] We estimated a total of 4.285 trillion barrels of oil in-place in the oil shale of this area using a geology-based assessment methodology.
In-place oil shale resources in the saline-mineral and saline-leached intervals, Parachute Creek Member of the Green River Formation, Piceance Basin, Colorado [ More info] We estimated 920 and 352 billion barrels of oil are potentially recoverable from oil shale resources using oil-yield cutoffs of 15 and 25 gallons per ton, respectively.
In-place oil shale resources of the Mahogany zone sorted by grade, overburden thickness and stripping ratio, Green River Formation, Piceance Basin, Colorado and Uinta Basin, Utah [ More info] Refinement of previous resource estimate taking into account the characteristics and quality of oil shale as well as the amount of overburden throughout this area.
Map of assessed tight-gas resources in the United States [ More info] Shows where there are potential commercial sources of natural gas trapped in formations with very low permeability to gas (not necessarily shale units). Hydraulic fracturing might be needed in order to exploit these resources.
Northern Gulf of Mexico ecosystem change and hazard susceptibility [ More info] Map interfaces and data in the area offshore Louisiana, Mississippi, and Alabama which was affected most by hurricane Katrina and, more recently, the oil spill.
Oil Pollution Impacts on Birds [ More info] A compilation of information, including reports, bibliographies, and data, on all aspects oil toxicity relevant to birds and other wildlife.
Potential for technically recoverable unconventional gas and oil resources in the Polish-Ukrainian Foredeep, Poland [ More info] Using a performance-based geological assessment methodology, we estimated mean volumes of 1,345 billion cubic feet of potentially technically recoverable gas and 168 million barrels of technically recoverable oil and natural gas liquids here.
Remaining recoverable petroleum in giant oil fields of the Los Angeles Basin, southern California [ More info] We estimated between 3.2 and 5.6 billion barrels of additional oil may be recovered with existing technology in this area using a probabilistic geology-based assessment methodology.
