Interpret seismic horizon environments

Seismic horizon slices from many depositional basins often reveal discernible seismic geomorphological features that can help narrow down possible depositional environments. These intervals may have limited well control and may require architectural interpretation based primarily on seismic element-based observations.

Improving the quality and confidence of depositional environment predictions based on seismic horizon data can significantly enhance decision-making and reduce subsurface exploration risks, leading to substantial economic benefits.

Use Sedbase Modern Analogues to Find Systems with Similar Geomorphological Features​

Identify geomorphological elements visible in your seismic horizon slices, such as channels or beach ridges, and assess their shapes and orientations. Use Sedbase's modern system datasets to find examples with similar geomorphological characteristics.

Learn from modern systems to make more informed interpretations of your subsurface seismic horizon intervals.

Use the View Analog and Dimensional Data application to find suitable modern analogues and make predictions about sub-seismic stratigraphic architecture in your interval.

Measure Dimensions of Seismic Channels and Find Matching Modern Analogues​

Measure the dimensions of seismic channels you have mapped in the subsurface, then use Sedbase to find modern channels and channel belts with comparable characteristics.

  • Improve geological predictions about the expected internal architecture of the identified seismic features (sand filled channel belt vs channel mud plug)
  • Assess the likely sizes of river systems that supplied the interval.
  • Determine possible adjacent depositional environments.

Use the View Analog and Dimensional Data application to locate channels and channel belts with similar dimensions, and leverage available geomorphological maps to predict local and regional depositional environments.
