Volume-based modeling that uses all available data and honors geologic rules.

Subsurface Modeling

Unique volume-based modeling.

3D SKUA structural model
 
In oil and gas exploration and production, state-of-the-art 3D modeling and construction of 3D grids is similar among competing applications: The conventional technique for constructing a model is pillar-based. Unfortunately, in environments containing Y faults or oblique faults, pillar-based construction requires modifications of the fault geometry and/or removal from the model, causing a mismatch between the structural and reservoir model and the interpretation.

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


Interpretation validation

Constructing a SKUA model from an interpretation is a first step in validating the interpretation. The model can be used to study the 3D structural integrity of the interpretation, as well as fault displacement, fault surface quality, and horizon interpretation quality (well marker mismatch, fault horizon intersections, etc.). With a SKUA model, it is also possible to look at the resulting 3D flattened seismic in SKUA UVT space. Any non-flat horizon in that space is incorrectly interpreted.

Prospect analysis

Using an interpretation and the resulting SKUA model, geoscientists can easily perform many different analyses to validate a prospect:

  • Faults
    • Displacement maps
    • Fault juxtaposition maps
    • Fault shale-gouge ratio and weighted shale-gouge ratio on faults
  • Volumetrics:
    • 3D consistent structural maps
    • Spill points
    • Volumetric uncertainty
    • Layer deformation
  • Deformation of the layers, strain and stress
  • Probability of fracturing and directions of fractures

Basin modeling

SKUA modeling can be applied at reservoir or basin scale:

  • The SKUA 3D gridding module enables the construction of special grids for basin modeling. Basin modeling grids differ from reservoir flow simulation grids in that cell faces should match the fault plane.
  • SKUA with Kine3D®-3 enables the sequential restoration of the basin grids from the present date to the depositional time.
