Paradox Basin

The Paradox Basin is an asymmetric foreland basin, developed along the southwestern flank of the Uncompahgre basement uplift in SE Utah and SW Colorado, USA. This large petroliferous basin (265km by 190km) formed during the Middle Pennsylvanian-Permian Ancestral Rocky Mountain orogenic event. Uplift and the generation of significant topography along the Uncompahgre thrust front provided the source and slope for deposition of thick alluvial fan sequences in the immediate footwall of the Uncompahgre thrust. These thick, prograding sequences provided the differential load on the underlying salt that triggered salt flow across the northern Paradox Basin.

Black Warrior Basin

Using a geology-based assessment, the U.S. Geological Survey estimated a mean of 8.5 trillion cubic feet of undiscovered natural gas, a mean of 5.9 million barrels of undiscovered oil, and a mean of 7.6 million barrels of undiscovered natural gas liquids.

Northeast Nevada Basin

Late Paleozoic tectonic events produced a wide variety of stratigraphic successions across the southern Great Basin. These strata accumulated in diverse sedimentary environments from a collisional foredeep on the west to the relatively unaffected platform on the east. The initial tectonic phase was the Antler orogeny, which emplaced siliceous marine sedimentary rocks and oceanic volcanic rocks of the Roberts Mountains allochthon eastward over passive margin strata (e.g., Nilsen and Stewart, 1980; Poole, 1981

Santa Maria Basin

Offshore oil and gas seeps have been reported to occur in the southern Santa Maria basin, but none has been documented with precise locations and geochemical analyses. In contrast, oil and gas seeps are extensive in the offshore Santa Barbara-Ventura basin, with major seepage occurring south of Coal Oil Point (Hornafius et al., 1999; Quigley et al., 1999).

The offshore Santa Maria basin is the most southern of seven basins in the Central California Province of the Pacific Outer Continental Shelf (OCS) Region. The basin trends northwest, is fault-bounded to the east and west, and is limited on the north by a structural discontinuity and to the south by the Amberjack structural high. Adjacent to and east of this structural high is the Santa Barbara-Ventura basin province. The offshore Santa Maria basin measures about 100 miles long and 25 miles wide, thus covering an area of about 2,500 square miles. This cruise focused on the southern most Santa Maria basin and area to the south and east adjacent to offshore Point Conception where oil and gas seeps have been previously described (Vernon and Slater, 1962, Wilkinson, 1971, Fischer, 1977).

Regional subsidence of the Santa Maria Basin resulted from regional extension during the early Miocene. Uplift and structural inversion of the basin began in the early Pliocene, reactivating normal faults and folding Miocene and Pliocene strata into anticlines, which are the structural traps for much of the petroleum found in this basin. More than 50 exploratory wells have been drilled in the southern and central parts of the offshore section of the basin, and, as of 1995, thirteen oil fields have been discovered (Mayerson, 1997). The explored stratigraphic section ranges from Jurassic to Holocene age and includes as much as 10,000 feet of Neogene strata. The principal hydrocarbon source and reservoir rock in the basin is the middle to late Miocene Monterey Formation.
