Abstract: 

To assist with risk-assessment with deepwater and ultra-deepwater prospects for offshore energy extraction as well as provide a useful tool for oil spill response, a spatial model was developed for comprehensive simulations of a blowout event from the wellhead to final fate and degradation. Already a complex modeling problem, blowouts on the ocean floor require modeling for high pressures, buoyant jet/plume physics, the importance of droplet sizes, and the presence of gas and gas-hydrates into simulations that already required a multifaceted approach. BLOSOM (Blowout and Spill Occurrence Model) is comprised of several components working in tandem to simulate the various states and phases experienced by a blowout event in great water depths, including a Lagrangian control-volume model for buoyant jets and plumes; a particle tracking model for the long-term fate and transport; a pseudo-components approach for handling crude oils and weathering processes; and equations of state adapted for hydrocarbons at high pressures.
