Abstract Before a wide range of enhanced oil recovery (EOR) techniques were implemented for an oilfield, the EOR potential and economic evaluation should be evaluated in advance each reservoir to determine which technique was proper. In oilfield developed with fluvial delta reservoirs, complicated distribution scattered small reservoirs vertical horizontal directions brought trouble work. A rap...

The potential of storing greenhouse gases in geological formations in the northeast portion of the Williston Basin is being investigated by researchers involved in the IEA Weyburn CO2 Monitoring and Storage Project. This project is linked to a CO2 miscible flood EOR program operated by EnCana Corporation in the Weyburn Midale Pool of southeastern Saskatchewan. A major component of the project i...

Floods early this year in Queensland, Australia, received a great deal of attention in the media because they affected a land area the size of Germany and France combined. However, on a world scale this is not exceptional as in some years the land area exposed to flooding is > 17 million km, equal to twice the size of the USA. These dramatic floods occur in all continents of our planet and resu...

In this study, the multiphase multicomponent Shan-Chen lattice Boltzmann method is employed to analyze impact of capillary force on oil-CO2-water fluid flow and enhanced oil recovery. Various sizes single throat are designed simulate interaction between displacing displaced phases as well their mechanical equilibrium. Several sensitivities taken into account, such wettability, miscibility, inte...

Climate change may affect the chemical composition of riparian leaf litter and, aquatic organisms and, consequently, leaf breakdown. We evaluated the effects of different scenarios combining increased temperature and carbon dioxide (CO2) on leaf detritus of Hevea spruceana (Benth) Müll. and decomposers (insect shredders and microorganisms). We hypothesized that simulated climate change (warming...

The effects of root zone temperature (RZT) and flooding on physiology and growth of Annona glabra L. (pond apple) and A. muricata L. (soursop) were investigated. Trees planted in containers were exposed to RZTs of 5, 10, 20, 25 or 35 degrees C in controlled root temperature chambers. Trees at each RZT were either non-flooded (control) or continuously flooded. There were four replications over t...

Temporary wetlands are short-term alternative ecosystems formed by flooding for irrigation of areas used for rice farming. The goal of this study is to describe the development cycle of rice fields as temporary wetlands in southern Brazil, evaluating how this process affect the gas production (CH4 and CO2) in soil with difference % carbon and organic matter content. Two areas adjacent to Lake M...
