SUMMARY:

The modeling of oil released from underwater sources is an important tool as it informs about the behavior of spilled oil, areas that can be affected, and provides a technical basis for the selection, development, and implementation of response actions. The Deepwater Horizon platform accident in 2010 in the Gulf of Mexico drew attention to the relevance of monitoring and prediction models, acting as a catalyst for the development of studies and strategies for optimization. The accuracy of such models depends directly on near-field modeling, observing the processes that occur immediately at the leak site, determining the dynamics of the plume and the resulting distribution of oil droplet sizes in the water. The study of these factors is of great importance for estimating outcomes in measures, for example the underwater application of dispersants around the release point. Several elements make the modeling of underwater leaks more complex than surface releases, such as constraints on accurately measuring prevailing oceanographic conditions and the limited availability of data in the initial hours of potential incidents, e.g., released volumes, exact location, leakage flow, composition, and thermodynamic conditions of the contaminating fluid, among others. In blowout scenarios, considered one of the main contributors to offshore activity risks, factors such as the influence of ocean currents, high pressures and low temperatures, and interaction with rocky layers and underwater sediments pose challenges in modeling the occurrences. In this context, this project proposes the application of recent knowledge in near-field modeling to analyze the behavior of an underwater oil and gas plume by simulating a blowout scenario in the Potiguar Basin (Rio Grande do Norte). The Texas A&M Oil Spill Calculator (TAMOC) model (2015), which uses a Lagrangian approach for the integral modeling of oil and gas particles in underwater plumes, will be used. Factors to be analyzed include the estimated time for the oil to reach the surface, the approximate location where the plume will reach the surface, the composition of the oil that will emerge on the surface, and the distribution of particle sizes along the plume. Through the analysis of obtained data, the research aims to enhance the understanding of the processes involved in underwater leaks and contribute to effective incident management of this nature in the studied region.
