Microbes consumed oil rapidly http://www.sciencedaily.com/releases/2011/08/ 110801111752.htm In the Deepwater Horizon oil spill in the Gulf of Mexico, the oil disappeared more rapidly than predicted. This article discusses some of the studies investigating the underlying causes of this rapid biodegradation. Oil spill is boon to bacteria http://classic.the-scientist.com/blog/display/57448/ This ...

The unprecedented engagement of scientists from government, academia, and industry enabled multiple unanticipated and unique problems to be addressed during the Deepwater Horizon oil spill. During the months between the initial blowout on April 20, 2010, and the final well kill on September 19, 2010, researchers prepared options, analyses of tradeoffs, assessments, and calculations of uncertain...

There is more diversity among microorganisms such as bacteria than there is in the range of life from artichokes to zebras. Bacteria have successfully colonized virtually e very environment on earth because they can rapidly adapt to changing conditions, and use a large and varied number of nutrients to generate energy. How e ve r, until relat ively recently, the environments of many petroleum r...

Tazhong Oil Field located in the center of Tarim Basin is one of the greatest discoveries during the petroleum exploration in Tarim Basin. The course of many years for hydrocarbon exploration and development has proved that there existed a much larger ancient reservoir than present-day reservoir and residual oil section below present WOC is of obvious characteristics of water displacement. Stud...

The process of storing natural gas in geological formations involves applying pressure to force the into and out porous permeable reservoir. In response extraction/withdrawal storage/injection, reservoir compresses expands as a major consequences fluid pore variations. challenge associated with this type energy systems is learning variations within grid being injected and/or withdrawn. As such,...

The effects of groundwater flow and biodegradation on the long-distance migration of petroleum-derived benzene in oil-bearing sedimentary basins are evaluated. Using an idealized basin representation, a coupled groundwater flow and heat transfer model computes the hydraulic head, stream function, and temperature in the basin. A coupled mass transport model simulates water washing of benzene fro...

Accurate prediction of petroleum reservoir performance requires reliable models of the often complex reservoir heterogeneity. Geostatistical simulation techniques generate multiple realizations of the reservoir model, all equally likely to be drawn. Traditional to geostatistics, geological continuity is represented through the variogram. The variogram is limited in describing complex geological...

 Production data analysis techniques have been widely used for estimating reservoir properties such as gas in place and average pressure. Knowledge of this information is crucial for proper reservoir management. The present study discusses the roadmap, challenges and uncertainties for analyzing production data in an Iranian gas-condensate offshore field. This work is an integrated study in...

Oil reservoir production systems are usually associated with a temperature gradient and oil production facilities frequently suffer from pipeline corrosion failures. Both bacteria and archaea potentially contribute to biocorrosion of the oil production equipment. Here the response of microbial populations from the petroleum reservoir to temperature gradient and corrosion of carbon steel coupons...
