Flashcards : Reservoir Heterogeneity and Anisotropy Fundamentals — 20 cartes

Fundamental rules describing spatial arrangement of rocks.

Indicates the reservoir's fluid storage capacity.

Affects fluid-rock interactions and capillary forces.

Volumetric change in response to pressure variations.

Rock's ability to transmit fluids.

Creates spatial variation in reservoir properties.

Uniform distribution of properties throughout the reservoir.

Affects vertical flow and recovery strategies.

Quantified by metrics like V and Lorenz coefficient.

Lateral variation of properties across the reservoir.

Estimate unknown values using spatial data and correlation.

Layering, mineral alignment, or microfractures.

Uniform properties in all directions.

Different properties depending on measurement direction.

Metric quantifying permeability heterogeneity.

Indicates degree of reservoir heterogeneity.

Layering and stratification affecting flow.

Often log-normal, skewed toward higher values.

Using uniformity coefficient and large-scale property consistency.

Both influence fluid storage and interactions.
