Maximum a Posteriori Prediction (MAP)

Produce more accurate inverted elastic properties by sampling from posterior Litho-Fluid Class (LFC) probabilities, ensuring more geologically consistent results.

Reservoir/Rock Property Prediction

Easily estimate constrained properties (e.g. porosity, shale volume) and their associated uncertainty, with the same confidence and as mainstay LFC probability and inverted elastic outputs. This feature, developed by Norsk Regnesentral (Norwegian Computing Center), strengthens the predictive power of inversion through a direct, extended, statistical link between elastic and reservoir/rock properties (via a robust logit transform). Whether identifying subtle variations in porosity, capturing heterogeneity, or differentiating clean sands from shaly intervals, this upgrade enhances your reservoir analysis with greater precision and confidence.

Well Zone Overlays: Connect the Dots Like Never Before

Integrate well zones created from well logs, geological markers, completion data, etc. with existing well data overlays and seismic volumes.

Whether you’re validating seismic processing results, correlating subtle reservoir changes, or optimizing reservoir evaluations and geosteering, these intuitive overlays make interpreting and integrating diverse datasets faster and easier than ever.

Scientific Color Palettes: Align with Visual Perception, Minimize Misleading Artifacts

Experience 12 new scientifically optimized perceptual color palettes that align with your perception and minimize misleading artifacts.

Processing geophysicists and quantitative interpreters will find it invaluable when analyzing subtle seismic attributes.

Reservoir geophysicists will gain clarity into fluid contacts, 4D effects, and reservoir structures.

Figure 3 – (Left) Viridis Perceptual Color Palette shows 4D differences that are more consistent and visually constrained to the reservoir when compared with (Right) a non-perceptual color palette (e.g. standard rainbow), which contains visual artifacts inside (warmer colors) and outside (cooler colors) the reservoir.

Expanded Interoperability & Performance:

• Enhanced export options support complex 4D/5D seismic differences and horizon/map data, facilitating smoother collaboration across platforms.
• Updated plugins for Petrel and DSG ensure smoother data transfers.
• The first of several planned performance improvements in the Multi-SEGY Import Helper boost productivity when handling extensive seismic stack datasets.

Usability & Reliability Improvements:

• Augmented crossplot session save/restore functionality now includes rock physics overlays, regression lines, and isolines, supporting consistent interpretation and analysis by allowing you to pick up exactly where you left off during a previous work session.
• Improved well data displays and log filtering now provide more comprehensive context, bridging the gap between seismic and log data.

Stay sharp with SRS 2024.2 –  Geophysicists and QI specialists will appreciate the smoother workflows, reduced uncertainty and enhanced confidence in reservoir characterization. Reservoir interpreters can leverage precise predictions to refine their interpretations and inputs to reservoir models, ultimately driving more informed operational decisions.
