    Subsurface Studies

    Rock Physics & Seismic Inversion

    Link rock properties to seismic signals to characterize reservoirs and reduce exploration risk.

    Rock Physics & Seismic Inversion - illustration

    Rock Physics Modeling

    Relate elastic properties to lithology, porosity, and fluids.

    Post-stack Inversion

    Derive acoustic impedance and reservoir trends.

    Pre-stack Inversion

    Estimate elastic properties (Vp, Vs, density) and AVO attributes.

    Decision Support

    Characterize reservoirs and reduce drilling risk.

    Core Features

    • Data Integration

      Integration of seismic (2D/3D), well logs, petrophysical data, checkshots, and core measurements into a unified framework.

    • Rock Physics Modeling

      Development of rock physics templates linking lithology, porosity, fluids, and elastic properties.

    • Well Log Conditioning

      Log editing, upscaling, fluid substitution, and depth–time alignment for inversion readiness.

    • Post-stack Seismic Inversion

      Acoustic impedance inversion to identify reservoir quality and lateral continuity.

    • Pre-stack Seismic Inversion

      Elastic inversion (AI, SI, Vp/Vs, density) for lithology and fluid discrimination.

    • AVO & Elastic Analysis

      AVO classification, angle gathers QC, and elastic attribute interpretation.

    Foundation Package

    • Data Inventory & QC

      Review, organize, and quality-check all seismic and well data.

    • Well Tie & Wavelet Extraction

      Seismic-to-well ties and wavelet estimation for reliable inversion results.

    • Rock Physics Feasibility Study

      Sensitivity analysis and feasibility assessment for post-stack and pre-stack inversion.

    FAQ

    Frequently asked questions

    Clear and concise answers to the most common questions about our rock physics analysis and seismic inversion services, supporting reliable reservoir characterization and decision-making.

    Ask our team

    We deliver rock physics modeling, well–seismic calibration, elastic and acoustic seismic inversion, and integrated interpretation workflows to predict reservoir properties.

    Typical inputs include well logs, core data (if available), seismic data, wavelets, velocity models, and existing interpretations. Data QC and conditioning are part of our workflow.

     These workflows link seismic response to rock and fluid properties, enabling quantitative prediction of lithology, porosity, and fluid distribution away from wells.

    We perform acoustic, elastic, pre-stack, post-stack, deterministic, and stochastic inversions, selected according to data quality and project objectives. 

    Deliverables include inverted property volumes, rock physics templates, well-to-seismic ties, interpretation maps, uncertainty analysis, and a comprehensive technical report.
