    Subsurface Studies

    Seismic Interpretation (2D, 3D & 4D)

    Turn seismic data into a clear picture of structures, horizons, and how the reservoir changes over time.

    Seismic Interpretation (2D, 3D & 4D) - illustration

    2D Seismic Interpretation

    Map regional structures and horizons along seismic lines.

    3D Seismic Interpretation

    Build detailed structural and stratigraphic frameworks from 3D volumes.

    4D Seismic Interpretation

    Track reservoir changes over time with repeated surveys.

    Decision Support

    Define prospects and guide well placement.

    Core Features

    • Data Integration

      Seismic, well, and geological data combined into a single coherent framework.

    • Well Seismic Calibration

      Well-to-seismic ties using logs, checkshots, VSP and markers to anchor horizons in time and depth.

    • Structural Interpretation

      Fault and horizon mapping that defines the structural framework of prospects and reservoirs.

    • Stratigraphic Interpretation

      Stratigraphic frameworks built from 3D volumes to delineate reservoir units and their extent.

    • Attributes Analysis

      Seismic attribute analysis and attribute volumes that support reservoir delineation and prospect definition.

    • Velocity Model & Time-Depth Conversion

      Velocity models calibrated to well data to convert interpreted horizons and faults from time to depth.

    Foundation Package

    • Data Inventory & QC

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

    • Seismic Interpretation (2D, 3D & 4D)

      Interpretation of seismic data to identify key horizons, faults, and structural features.

    • Maps & Sections

      Key structural, facies, and property maps and cross-sections.

    FAQ

    Frequently asked questions

    Clear and concise answers to the most common questions about our seismic interpretation services, including 2D, 3D, and 4D workflows.

    Ask our team

    We provide end-to-end seismic interpretation services including 2D, 3D, and 4D seismic interpretation. Our scope covers structural and stratigraphic interpretation, fault and horizon mapping, seismic attributes analysis, time-lapse (4D) interpretation, and integration with well and geological data.

    Typical inputs include seismic datasets (2D/3D/4D), well data (logs, checkshots, VSP, markers), velocity models, and any existing interpretations. We also perform data inventory, conditioning, and quality control (QC) as part of the project initiation.

    Our interpretations support prospect generation, reservoir delineation, well placement, and field development planning, reducing subsurface uncertainty and risk.

    Yes. We perform 4D seismic interpretation to monitor reservoir changes, fluid movement, and pressure evolution, supporting reservoir management and EOR strategies.

    Deliverables include interpreted seismic sections, fault and horizon maps, attribute volumes, prospect maps, and a comprehensive technical report compatible with industry-standard software.

    22+ seismic interpretation projects (2D, 3D, time-lapse)

    Fault & horizon interpretation on datasets up to 5,000+ km²

    Support for exploration screening, reservoir monitoring, and field redevelopment
