Energy plays a global strategic role, with the oil industry being a crucial source. However, initiatives aimed at reducing dependence on oil are emerging, mainly driven by environmental concerns such as climate change. Energy transition gains prominence in national agendas, reflecting the interconnectedness between energy and the environment. Despite the reduction in the demand growth forecast, the global oil and gas industry, the oil industry remains vital, sustaining energy sources, generating revenue, and jobs. However, the industry faces increasing environmental pressures, highlighting the need for continuous investment in safety in well drilling operations. Blowouts, although events with low probability of occurrence, represent a serious threat not only to the company s image but also to the environment and people s lives. The example of the Macondo blowout in the Gulf of Mexico, during British Petroleum (BP) operation, illustrates significant impacts. Combatting blowouts involves impact mitigation and source control. Essential strategies for impact mitigation and source control include well capping and the construction of a relief well. The former is a rapid action to close the well and stop hydrocarbon leakage into the environment, while the latter aims to build an additional well to intercept, killing, and permanently abandon the blowout well. This work focuses on presenting solutions for blowout well killing via relief well in situations requiring high flow rates and volumes. Simulations reveal technical challenges, such as demands for large volumes and high pump rates. Therefore, the research seeks to offer differentiated solutions to meet these specific demands and contribute to the safety and effectiveness of operations.
