Wilcox Tight Gas Sandstone: Multiscale Model Predictions of Transport Properties

A process-based multiscale network modeling approach predicts drainage capillary pressure and relative permeability curves for Wilcox tight gas sandstone. The modeling is informed from thin sections and covers early cementation, final cementation, and feldspar dissolution stages. Predictions are also made from a two-scale analysis of an X-ray tomographic image, though computational limitations are noted.

Use Cases

• Predicting drainage capillary pressure curves based on process-based multiscale network modeling.
• Modeling relative permeability-wetting phase saturation curves for different paragenetic stages like early cementation.
• Comparing model predictions informed from thin sections against those derived from X-ray tomographic image analysis.

Strengths

• Modeling approach is informed from physical thin sections, providing a process-based foundation.
• Predictions cover multiple geological stages (early cementation, final cementation, feldspar dissolution).
• Includes analysis based on an X-ray tomographic image for a two-scale perspective.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Computational limitations are noted for the X-ray tomographic image analysis, making conclusions uncertain.
