Environmentally Friendly Drilling (EFD) Systems

Uncertainty-Based Selection of EFD Systems


Our objective is to develop a Risk-based decision system capable of generating probabilistic dynamic maps, which can be accessed online, for the simulation of community-based scenarios that can facilitate the decision-making related to EFD systems at present and future time, with the aim of lowering drilling environmental impact, while making it a still cost effective activity, with favorable public opinion.
