Abstract:

The Texas A&M Oil spill (Outfall) Calculator (TAMOC) is a numerical model for simulating the physical, chemical, and thermodynamic behavior of petroleum fluids released from an accidental oil well blowout. The fate of oil in the ocean water column depends on the release conditions, the initial oil droplet and gas bubble size distributions, and the chemical composition of the released oil. This dataset contains a set of sensitivity runs of the TAMOC suite in which one of the initial conditions is changed in order to understand the effect of that initial condition on the overall model simulation. Conditions that were varied in the sensitivity analysis include varying the chemical processes associated with dispersed phases in the plume and the oil and gas composition.
