SKUA Structural Analysis
Yes, you can create the most reliable 3D models of the earth’s subsurface.
SKUA™ - Subsurface Knowledge Unified Approach - is a huge leap forward in geologic characterization. Based on our proprietary UVT Transform™ algorithm, the SKUA software suite reduces modeling times from months to days. The SKUA platform’s built-in data sharing, multiple scenario processing, and audit trail improve E&P workflows, reduce study time, and create the industry’s most accurate models for planning and forecasting.
Dramatic improvements in reservoir modeling
The UVT Transform algorithm removes the constraints of traditional pillar-based technology. It delivers a consistent representation without “dumbing down” the data, which means that users no longer need to simplify their interpretations.
SKUA models can be directly applied to a number of structural analysis puzzles, including:
- Fault displacement maps
- Fault displacement versus length/area analysis
Reservoir juxtaposition or fault trap information can be extracted from the SKUA stratigraphic faulted model. The UVT Transform algorithm that powers SKUA contains the information needed for computations, such as strain/stress information, smear gouge ratio or weighted smear gouge ratio. UVT Transform also computes fracture probability volumes, given the rock parameters.
3D structural restoration can be done directly on a SKUA structural model without the need to create a tessellated mesh.
The SKUA model can be used directly. No "re-tooling" is needed, nor are there fault geometry simplifications. Geoscientists can use SKUA UVT information to correctly compute the displacement of particles against fault surfaces, as well as the stress/strain/fracture probability directly from the UVT transform. Validation of UVT transformation is provided by interpretation in the 3D UVT flattened space with seismic.
Other features include:
- Juxtaposition maps in any structural setting, honoring all interpreted faults.
- Weighted shale gouge ratio, computed using an additional parameter - the maximum smearing distance of the shale from its "origin" inside the fault plane. A typical shale-gouge ratio assumes that the shale layer is smeared equally along the fault plane. The clay smear potential is sometimes used as well, but the weighted shale gouge ratio combines both types of information.
- Ability to compute the probability of fracturing and the direction of fractures at any location in a reservoir, from the deformation and mechanical attributes of the rock type inside the layer.
- 3D flattening of seismic volumes to perform interpretation QC and UVT model QC.
