Flooding induced several physiological and morphological changes in Fraxinus pennsylvanica seedlings, with stomatal closure among the earliest responses. Subsequent changes included: reduction in dry weight increment of roots, stems, and leaves; formation of hypertrophied lenticels and production of adventitious roots on submerged portions of the stem above the soil line; leaf necrosis; and lea...

Decline curve analysis models are frequently used but still have many limitations. Approaches of decline curve analysis used for naturally-fractured reservoirs developed by water flooding have been few. To this end, a decline analysis model derived based on fluid flow mechanisms was proposed and used to analyze the oil production data from naturallyfractured reservoirs developed by water floodi...

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...

Core flooding experiments are used for testing enhanced oil recovery strategies (EOR) on a laboratory scale. In a typical core flooding experiment, the core plug contains oil, water and potential EOR agents. It is of importance to understand the multiphase flow of these liquid inside the porous rock formation. The combination of X‐ray CT scanning and image analysis has been used to study multip...

Several British-sponsored state-of-the-art assessments of the global impacts of climate change on various climate-sensitive threats (namely, malaria, hunger, water stress, coastal flooding, habitat loss, carbon sink capacity, and coastal wetlands) using the major scenarios developed by the IPCC indicate that through 2085 to 2100, i.e., the foreseeable future, the contribution of climate change ...

This study is an attempt to develop an integrated methodology to predict the impact of the Caspian Sea on flooding using Geographic Information Systems (GIS) and hydrodynamic modeling. A rise in the sea level might lead to major flooding events, and have a severe impact on the spatial development of cities and regions. The feasibility of simulating a flood event along a drain channel is evaluat...

Core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating CO2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. The core samples were provided from a low permeability mixed wet oil reservoir at 156 °F and 1900 psia. In addition, very few studies of surfactant adsorption on car...

Hydrological restoration of historically isolated wetlands may mitigate phosphorus (P) loss. The objectives of this study were to quantify P in soil, determine effect of (1) soil characteristics on P release, and (2) antecedent soil hydrological conditions on P dynamics. Humic/fulvic acid bound P and residual P accounted for majority of P (>78%) in surface soils. Soils with highest nutrient sta...

Students walking to their first classes of the new year had to get past more than just their snooze buttons. According to weather data on the university website, Rice's campus received 4.98 inches of rain Monday, flooding roads and parking lots in and around the university. The university sent a message over the emergency notification system at 10:01 a.m. to warn students, faculty and staff tha...
