Valid fault seal analysis honoring all data.

Interpretation Validation

Accurate interpretation leads to more accurate models.

The result of an interpretation, whether automatic or manual, is a sparse representation of a series of horizon and faults. These representations are then transformed into a structural model where faults form a consistent fault network and horizons are correctly faulted. By using all of your data, avoiding simplifications, and working within the revolutionary 3D Common Earth Model, the Paradigm® Subsurface Modeling solution, powered by SKUA®, ensures accurate interpretations and therefore more accurate geological or reservoir models.

The Paradigm Subsurface Modeling solution is based on the SKUA modeling platform, which itself is based on the fundamental UVT Transform® algorithm. SKUA revolutionizes the world of subsurface modeling by greatly streamlining the creation of a consistent structural and stratigraphic model without simplifications or the use of pillars.


Modeling while interpreting

Validate the fault network with respect to seismic
 
In the past, modeling limitations made maintaining synchronization between the model and the current interpretation difficult. Users lacked the time and expertise needed to efficiently perform these workflows. The Paradigm Interpretation Validation solution has succeeded in streamlining this process while preserving the complexity and fidelity of the subsurface interpretation. This breakthrough provides geoscientists with the full range of benefits to be gained by modeling while interpreting::

  • SKUA is able to honor all interpretation data and build a geologically coherent structural model in "one click".
  • The one-click button between SeisEarth® and SKUA enables users to send their interpretation to SKUA, and to retrieve the fault network, the stratigraphically consistent horizons extended to the fault planes, and the associated fault polygons.
  • The SKUA 3D seismic flatten view, where all horizons are flat and unfaulted, provides a way to quickly check if the horizon interpretation matches the seismic events.

Illumination analysis

The Paradigm full-azimuth illumination application is an advanced seismic data mining tool that provides a previously unattainable breadth of knowledge about ray propagation in complex areas. It uses an advanced, interactive ray tracing technology that quantifies the relationship between the surface acquisition geometry and subsurface angles in targeted areas.


Structural analysis

SKUA models can be used directly to perform a number of structural analyses:

  • Fault displacement map
  • Fault displacement vs. length/area analysis
  • Reservoir juxtaposition or fault trap information can be extracted from the SKUA stratigraphic faulted model. The UVT Transform contains all the information needed to compute information such as Smear Gouge Ratio or weighted Smear Gouge Ratio, which takes into account the smearing potential.
  • 3D structural restoration can be done directly on a SKUA structural model without the need to create a tesselated mesh.
  • Strain/stress information from the SKUA UVT Transform
  • Fracture probability volumes can be computed from the SKUA UVT Transform and rock parameters.
