Core Analysis
What sedimentological analyses are performed by NiMBUC Geoscience?
For a sedimentological analysis, the rocks are described, listing their lithological inventory, sorting, classification, structures, boundaries, fossils, components, etc. The rock facies and depositional environment can be determined and is also used to tune the image facies in the same or in nearby wells.
What structural core analyses are performed by NiMBUC Geoscience?
Structural core analysis records all features related to brittle or ductile deformation, such as fractures, faults or small-scale folds intersecting the borehole. We pay special attention to the tectonic history and timing of deformation, which can have tremendous effects on the reservoir properties.
What are the results of the combination of Structural Core Analysis with Core Goniometry?
- True feature orientation (in combination with core goniometry)
- True fracture intensity (well orientation-corrected, only in combination with core goniometry)
What are the results of the Structural Core Analysis?
- Presentation of all tectonic features by genesis, orientation and aperture/fill
- Apparent fracture intensity and fracture spacing
- Calculation of strain axes to derive the principal shortening/stretching direction
- Interpretation of relative tectonic history based on cross-cutting relationships
How can structural core analysis be enhanced?
Structural core analysis is particularly powerful in combination with classical core goniometry or image-based goniometry. The true orientation of core structures facilitates the spatial analysis and allows reconstruction of the tectonic history of a reservoir.
