Benefits of Analyzing Prestack Seismic Data Combined with Advanced Interpretation and Visualization Tools to Improve Seismic Reservoir Characterization of Highly Faulted Reservoirs
Summary Recent advances in software development have enabled seamless use of prestack seismic data combined with advanced attributes and high end interpretation and visualization workflows. We describe a new workflow that gives geophysicists and geologists more flexibility in checking the quality of prestack seismic data and helps them select the best angle stacks for amplitude and structural interpretation. This can be crucial to achieving a better understanding of the prospect geometry and better structural definition. The novelty of this approach is a new workflow to combine the two chosen angle stacks; the one with the most suitable amplitudes, and the one with the best fault detection, using a hybrid cube. This resulting hybrid cube becomes the seed for the second stage of the workflow, which involves the use of advanced interpretation and visualization tools that lead to better seismic reservoir characterization. This approach, coupled with advanced attributes, 3D interpretation, and visualization functionalities, significantly improves prospect delineation, especially in creating a better image of the prospect geometry and better structural definition. This workflow can also help remove the subjectivity around faults interpreted manually and could help in the early stages of modeling, well design and planning.
