Comprehensive Seismic Interpretation Workflow
With subsurfaceAI for Geophysicists, you can execute a complete 2-D and 3-D integrated seismic interpretation and attribute analysis project through the following workflow:
- Import Seismic Data: Easily import multiple 2-D and 3-D seismic datasets into your project, with support for worldwide geographic projections.
- Import Well Data: Seamlessly integrate well data, including well headers, directional surveys, well logs, and existing well top interpretations in various formats.
- Incorporate Existing Interpretations: Utilize available 2-D and 3-D horizon picks, fault sticks, and other seismic interpretation results.
- Integrate Culture Data: Import cultural data in geographic data formats for comprehensive analysis.
- Seismic Survey Alignment: Correct for differences in time, amplitude, and frequency across different seismic data vintages.
- Identify New Reservoir Targets: Detect new reservoir targets through well top or well log facies interpretation on well sections.
- Well and Seismic Data Correlation: Tie well data to seismic data using synthetic seismograms and match well tops with seismic horizons.
- Seismic Data Conditioning: Enhance signal-to-noise ratio through edge-preserving noise filtering, PCA analysis, and image enhancement before attribute calculation.
- Attribute Calculation: Compute various seismic attributes, including fault likelihood, semblance, volume curvatures, instantaneous attributes and spectral decompositions.
- Fault Picking: Identify faults on seismic sections, base maps, or 3-D windows.
