Adrok’s technology can infer bulk density, but indirectly—not through direct measurement like a density log or core analysis. The inference is made through correlations between bulk density and other electromagnetic (EM) properties, especially:
- Dielectric permittivity
- Atomic dielectric resonance (ADR) frequency responses
- Energy absorption and reflection characteristics
How Bulk Density Is Inferred by Adrok
1. Dielectric Constant vs Density Relationship
- In general, dielectric permittivity increases with bulk density, especially in dry, non-porous rocks.
- Denser rocks (like granite or basalt) typically have higher dielectric constants than porous or less compacted rocks (like sandstone or clay).
2. Resonance Pattern Matching
- ADR scans identify resonant frequencies that correlate with specific mineral compositions and packing densities.
- By comparing signal responses to known lithological libraries (from well logs, lab measurements, etc.), Adrok can estimate density ranges.
3. Machine Learning/Statistical Modelling
- In practice, Adrok uses training datasets where the EM response (including dielectric, resonance, and reflection data) is matched with known physical properties from well logs.
- These models can predict bulk density in new areas by analogy.
📊 Precision & Accuracy
- Relative estimates: ADR provides relative bulk density trends, identifying denser vs. less dense zones.
- Quantitative precision: Not as precise as direct methods (e.g., gamma-gamma density logs), but useful for geological modeling and lithology discrimination.
- Best use: Early-stage exploration or where drilling is limited.
