Levee Analysis and Design for Proposed Missouri Refining Co. Petroleum Refinery Site.
… levee around the proposed Missouri Refining Co. petroleum refinery, see Figure 1 for location. The location is near the confluence of the Yellowstone and Missouri Rivers in Williams County, North Dakota. The recent success in extracting unconventional petroleum reserves in the Williston Basin has …

Ruthenium complexes of nitrogen- and sulfur-containing heterocycles
In the United States conventional crude petroleum reserves were depleted by 21.3% between 1978 and 1991, and is reflected by the fact that the crude oil pool has gotten heavier. Heavier crudes are associated with higher boiling point hydrocarbon fractions as well as high levels of sulfur, nitrogen, …

Sumak kawsay as generative of a new indigenous identity in the Amazonian region of Ecuador
… monetizing natural resources, in particular the petroleum reserves beneath Amazonia. At the insistence of representatives of the indigenous peoples, it was inscribed in numerous places in the Ecuadorian Constitution of 2008, and even if not yet enforced by the national government, it expresses an …

Engineering lipases and solvents for trans/-esterification of used vegetable oils
<p>Diminishing petroleum reserves and increasing environmental awareness has led to an urgent need to develop alternative fuels, such as biodiesel. However, the conventional method to produce biodiesel uses environmentally harmful chemical catalysts. A relatively new development in the production …

Microbial engineering for aldehyde synthesis
… renewable carbon sources instead of from finite petroleum reserves. Aldehydes represent a class of chemicals that has been challenging to obtain using microbes given the rapid conversion of aldehydes into their corresponding alcohols that occurs naturally. Microbes are thought to have evolved …

Microbial transformation of lignin
Petroleum reserves are forecast to dwindle during the next century. The imminent shortage of chemicals derived from fossil fuels has given an impetus to research on utilization of renewable resources throuqh microbial treatment. This work looks at the concept of lignin bioprocessing from the …

The stratigraphy and economic potential of Permo-Pennsylvanian strata in southwestern North Dakota
… several areas with good potential for additional petroleum reserves because of trapping conditions and proximity to source rocks. Porous and permeable intervals in the Dickinson and Bismarck lithozones and in the Broom Creek Formation have potential where trapping mechanism and source beds …

Potential Petroleum Reservoir Rocks of North-Central Oregon
<p>Petroleum explorationists have commonly assumed, based on the presence of volcanic and/or volcaniclastic rock, that regions such as northcentral Oregon do not hold potential as petroleum basins. The typical argument has been that volcanic flows have no effective porosity or permeability and …

Investigating the effect of perforation diameter and carbon dioxide bubble size distribution on heavy oil recovery
… consumption coupled with depleting conventional petroleum reserves. To address this challenge, heavy oil has been considered as a strategic petroleum resource that can be produced intensively to supplement the global supply of conventional hydrocarbons. In recent years, thermal-based techniques, …

Diagenetic controls of reservoir quality in the Mississippian Wayne Beds in the Williston Basin, Bottineau County, North Dakota
… lithofacies; however, the ultimate recoverable reserves of oil per well is controlled neither by structure, nor by depositional environments. </p><p> The Wayne beds underwent cementation and micritization in the marine phreatic diagenetic environment. Hypersaline diagenesis caused minor …

"All the Crises Reached a Concerted Crescendo" - The Arab Oil Embargo and Why the United States Was Unprepared for It
During the 2008 spike in oil prices, oil companies and government officials were brought under close scrutiny as many Americans began to question why prices were able to rise so quickly. Americans had become accustomed to living in an economy where cheap oil was the norm, and demanded answers when …
