SKUA Modeling Platform

A Step-Change in Modeling


Sub-surface modeling is an essential prerequisite for accurate volumetrics, whether static or dynamic; however, the task of transforming interpretation to a 3D model has been always tedious. SKUA introduces a revolutionary approach that preserves interpretation data while greatly simplifying modeling as well as all the processes that use a model, such as 3D restoration, 3D fault seal analysis, velocity modeling, flow simulation and mapping.
 

 

Removing pillars dramatically improves geologic modeling

The UVT Transform® algorithm is a mathematically derived 3D methodology that generates a volume description of the subsurface, including the structure, stratigraphy, geological grid, and flow simulation grid.  It uses ALL of your data, without simplification.

UVT Transform removes the constraints of traditional (pillar-based) technology. Without pillars, SKUA users are able to create more accurate models of the subsurface. The algorithm delivers a consistent representation without “dumbing down” the data, which means your team will no longer need to simplify their interpretations. In addition, UVT Transform brings a wealth of new opportunities to all of your E&P workflows.
 

Workflow optimization

A SKUA UVT model can be used to construct (typically in one step):

  • Velocity models for imaging
  • Geological grids for geostatistical simulation of rock properties, computed directly from the UVT model without any additional user interaction
  • Reservoir grids for reservoir simulation extracted directly from the UVT model. The only optional user interaction is the definition of potential alignment to faults.
  • Consistent structural maps with UVT implicit stratigraphic rules.
  • Geomechanical grids for geomechanical simulation (with a link to Abaqus) or coupled flow-geomechanical simulations
  • 4D basin modeling grids (combining SKUA model and 3D restoration in Kine3D®-3)
  • Paleo-flattening of seismic volumes to perform interpretation QC and UVT model QC

Geologically constrained volume modeling

The SKUA UVT model is geologically constrained by a series of rules. These include:

  • Sequential stratigraphic rule and erosion rules. Example: Ensure that the horizon was not deposited in a particular area or that two horizons in the same stratigraphic sequence cannot cross.
  • Dip/azimuth information anywhere in the volume. Example: Well dip meter data or surface dip measurements provide internal layer geometry information used by the UVT Transform.
  • Well path information. Example: The layer geometry is constrained by the fact that a particular section of the well path did not intersect the top or base of the layer.
  • Fault type (normal, inverse) information. Example: Ensure that horizon contacts do not cross on the fault plane.
  • Intra-formation chrono-stratigraphy. Similar to dip meter data, intra-layer picks can be used to better control the UVT Transform, which in turn provides better alignment between the UVT space and the seismic signal.  This is a sine qua non condition for correctly merging well and seismic information away from the wells.
