A knowledge-based heterogeneity characterization framework for 3D steam-assisted gravity drainage reservoirs
作者:
Highlights:
• A hybrid deep learning-based workflow is developed to infer 3D shale heterogeneities.
• Novel inputs and outputs parameterization schemes are explored via wavelet transform.
• Deep learning is applied as a proxy of flow simulation to evaluate objective functions.
• Fast and satisfactory heterogeneities characterization in 3D reservoirs are obtained.
• Multiple characterized models exhibit similar shale distribution as the true model.
