Taking seismic-to-well calibration to the next level.

Seismic-to-well calibration is performed in order to integrate seismic and well data to build a consistent picture of the subsurface. While seismic data alone provides a good overall picture of a large subsurface area, well data delivers a high-resolution, detailed and quantitative picture of the subsurface at a single location. Integrating these datasets is the only way to obtain a detailed quantitative picture of an areal subsurface. This makes seismic-to-well calibration a central component in any seismic interpretation or reservoir characterization workflow. Seismic-to-well calibration is often referred to as a “synthetics utility” because its basic action is calculating a “synthetic seismogram”.

Unlike traditional offerings, in SeisEarth calibration is performed within the main visualization window, as a natural extension of the interpretation workflow. Multi-attribute seismic and multi-attribute synthetics are automatically matched with one mouse click. A unique multi-well functionality enables the simultaneous processing of many wells within a shared visualization framework, enabling easy QC and management of the calibration workflow. In the multi-well approach, all wells can be processed together in a well-defined and logical workflow, generating a single wavelet that characterizes the seismic data.

Synthetics benefits

  • Well-to-seismic calibration performed directly in the main windows enhances efficiency.
  • A valuable tool for casual users and experts, as it is easy to use, yet sophisticated and comprehensive.
  • Unique multi-well and multi-attribute design significantly reduces workflow complexity.
  • Automatic and interactive processes help compress time to decision.

Synthetics features

  • Well-to-seismic calibration integration performed entirely within the Paradigm multi-attribute interpretation environment (Section Window) with multi-attribute seismic and synthetics are automatically matched at a click of a button.
  • Modeling and calibration: Zero and non-zero offset elastic modeling generates both synthetic seismograms and synthetic gathers.
  • Modeling of multiples
  • Multi-well capabilities: Many wells may be simultaneously processed within a multi-well visualization framework, enabling users to easily QC and manage the calibration workflow.
  • Multi-attribute functionality: Various synthetic seismograms corresponding to AVO and other attributes are automatically displayed in relevant seismic/attribute datasets. Multi-attribute wavelet extraction produces a separate wavelet for each attribute.
  • Integrated crossplotting: Crossplots logs, synthetic seismograms and seismic data, and calibrates in crossplot space.
  • Comprehensive display: All relevant logs, seismic data and synthetic seismograms are displayed in a dedicated window.
  • Checkshot calibration analysis
  • Dynamic stretch and squeeze: Performed together with drift analysis in a multi-attribute environment, with logs and synthetic visualization.
  • Correlation maps: Enables users to optimize time-phase shift analysis and find the best lateral position for calibration.
  • Deviated wells: Calibration on deviated wells can be performed in true 3D, and visualized dynamically within the interpretation framework.
  • Well-to-seismic calibration in depth:  Calibrate once only and automatically obtain synthetics calibrated in any domain. Enables a consistent wavelet extraction procedure for inversion of depth data.
  • Rock physics modeling: Synergy between well-to-seismic calibration and rock physics modeling enables, for instance, interactive analysis of the effect of fluid/porosity changes on synthetic seismograms.
  • Full volume modeling: Easy production of full volume, synthetic datasets of various attributes, as well as full 3D pre-stack datasets.
