of a thesis at the University of Miami. Any prediction based on numerical model contains uncertainty. The Deepwater Horizon oil spill forecast is a challenge due to the difficulty in measuring key parameters and the complexity in predicting the oil fate. Monte-Carlo (MC) sampling are applied to quantify the forecast uncertainties in an integral oil plume model simulating the Deepwater Horizon o...

within the framework of international political economy, this article discusses the situation of energy resources, including oil and gas, in central asia and argues that due to abundance of oil and gas resources in such countries as kazakhstan, turkmenistan and uzbekistan, and hefty revenues generated by those resources, statesmen in these countries are planning to turn central asia into a majo...

Silicone based oil is heated in the boiler of the diffusion pump and the vaporized oil rises in the central tower and streams out of directional flutes directed downward in the pump throat. This allows air molecules to dissolve in the gaseous oil (gas dissolved in gas). As the oil-air mixture cools (due to water cooling coils wrapped around the pump throat) the oil condenses and returns to liqu...

Organizations operating in the oil and gas sector face enormous challenges, including the pressing need to find and exploit new energy supplies, greater regulatory pressures, new workflow requirements, and the demands of a a changing professional labor force. At the same time, upstream companies face a serious and growing risk from cyber-attacks, malicious software, and other threats against th...

Strong foam can be generated in porous media containing oil, resulting in incremental oil recovery; however, oil recovery factor is restricted. A large fraction of oil recovered by foam flooding forms an oil-in-water emulsion, so that costly methods may need to be used to separate the oil. Moreover, strong foam could create a large pressure gradient, which may cause fractures in the reservoir. ...

Grieve oil field, discovered in 1954, is located in southeastern Wind River Basin, central Wyoming. This Lower Cretaceous, valley-fill and channelized, Muddy sandstone reservoir is a stratigraphic/structural trap with an average structural dip of 15 degrees. Multiple recovery mechanisms have contributed to produce more than 30 million barrels of premium light sweet crude, including gas expansio...

Understanding the sources and quantities of greenhouse gas (GHG) emissions is critical to developing an emissions inventory that accurately represents various oil and gas industry segment operations. To address this, the American Petroleum Institute (API) formed a Greenhouse Gas Emissions Methodology Working Group. The working group’s objectives were to review, summarize and recommend methodolo...

This study proposed a novel way for global greenhouse gas reduction through reusing China's waste oil to produce biofuels. Life cycle greenhouse gas mitigation potential of aviation bio-kerosene and biodiesel derived from China's waste oil in 2010 was equivalent to approximately 28.8% and 14.7% of mitigation achievements on fossil-based CO2 emissions by Annex B countries of the Kyoto Protocol i...

The drilling time data of gas logging are used to calculate drilling time ratio of the reservoir, and the total hydrocarbon data are used to calculate hydrocarbon contrast coefficient and to establish the drilling time ratio--hydrocarbon contrast coefficient crossplot. The standards of distinguishing the boundaries of hydrocarbon zones, hydrocarbonaceous water layers and dry layers are determin...
