During the Deepwater Horizon disaster, a substantial fraction of 600,000-900,000 tons released petroleum liquid and natural gas became entrapped below sea surface, but quantity sequestration mechanisms have remained unclear. We modeled buoyant jet droplets, bubbles, entrained seawater, using 279 simulated chemical components, for representative day (June 8, 2010) period after sunken platform's riser pipe was pared at wellhead 4-July 15). The model predicts that 27% mass fluids dissolved into...
Abstract The transport of oil droplets following a surface spill was investigated using uniform vertical eddy diffusivity model and the K‐profile parameterization model, which assumes maximum K value at 1/3 depth mixed layer. initial droplet size distribution obtained based on Delvigne Sweeney (1988, https://doi.org/10.1007/s13131‐013‐0364‐7 ) model. Using ave , an exact analytical solution used to produce transient steady state profile concentration all sizes. It found that is proportional...
Abstract Gas is often emanated from the sea bed during a subsea oil and gas blowout. The size of bubble changes due to dissolution in ambient water expansion as result decrease pressure rise. It important understand fate transport bubbles for purpose environmental safety concerns. In this paper, we used numerical model, VDROP‐J simulate formation jet/plume upon release, while rising relatively shallow model predictions were an excellent match experimental data. Then module was included...
The interaction of oil and sediment in the environment determines, to a large extent, trajectory fate oil. Using confocal microscope imaging techniques obtain detailed 3D structures oil–particle aggregates (OPAs) formed turbulent flows, we elucidated new mechanism particle attachment, whereby particles behave as projectiles penetrating droplets depths varying from ∼2 10 μm due hydrodynamic forces water. This results higher attachment on comparison with adsorption, commonly assumed....
While chemical dispersants are a powerful tool for treating spilled oil, their effectiveness can be limited by oil weathering processes such as evaporation and emulsification. It has been suggested that photo-oxidation could exacerbate these challenges. To address the role of in dispersant effectiveness, outdoor mesocosm experiments with crude on seawater were performed. Changes bulk properties molecular composition quantified to characterize over 11 days. test relative residues evaluated...
Abstract Numerical experiments of oil bioremediation tidally influenced beach were simulated using the model BIOMARUN. Nutrient and dissolved oxygen assumed present in a solution applied on exposed face, concentration these amendments was tracked throughout for up to 6 months. It found that, comparison natural attenuation, increased removal efficiency by 76% 65% alkanes aromatics, respectively. Increasing nutrient did not always enhance biodegradation as became limiting even when originally...
Abstract Improved understanding of the character an uncontrolled pipeline flow is critical for estimation oil discharge and droplet size distribution both essential evaluating spill impact. Measured gas properties at wellhead Macondo255 detailed numerical modeling suggested that within pipe could have been “churn,” whereby tumble violently different from bubbly commonly assumed release. The churn would produced 5 times energy loss in compared to flow, its plume entrained 35% more water than...
