Speaker: Konrad Wojnar – Resoptima
Topic: Assimilation of 4D seismic data for probabilistic modelling using ensemble-based methods
A standardized approach to application of 4D seismic data to reservoir characterization and history matching is yet to be adopted by the industry. In this talk I will present an ensemble-based workflow to systematically screen, analyze and history match production and 4D seismic data. I will focus on why ensemble-based methods are better suited for data with high dimensionality and why they are less prone to overfitting than traditional machine-learning data conditioning algorithms. Moreover, I will discuss how the workflow can be used to explore different modelling scenarios and thus improve reservoir management.
