Steady State Permeability

As received or extracted intact sample analysis for gas permeability (ability to flow a fluid at a  given rate over time). Ambient or stressed conditions up to 10k psi overpressure.

Can be performed on intact or crushed rock volume. Ideally a minimum of 50-60 grams per sample. If seeking to execute entire workflow design ~120 grams of starting intact material is required. Exception is SS permeameter. Only intact analysis applies.

Bulk density

Bulk sample density vis Archimedes method from flourinert immersion measurement.

Can be performed on intact or crushed rock volume. Ideally a minimum of 50-60 grams per sample. If seeking to execute entire workflow design ~120 grams of starting intact material is required. Exception is SS permeameter. Only intact analysis applies.

Grain density

As received and/or thermal and/or chemical extracted state analysis. Resulting grain density provided.

Can be performed on intact or crushed rock volume. Ideally a minimum of 50-60 grams per sample. If seeking to execute entire workflow design ~120 grams of starting intact material is required. Exception is SS permeameter. Only intact analysis applies.

Porosity

Total storage volume quantification by Helium porsimetry measurement.

Can be performed on intact or crushed rock volume. Ideally a minimum of 50-60 grams per sample. If seeking to execute entire workflow design ~120 grams of starting intact material is required. Exception is SS permeameter. Only intact analysis applies.

Fluid saturation

Water and hydrocarbon quantified fluid saturations based on retort analysis (closed and/or open designs).

Can be performed on intact or crushed rock volume. Ideally a minimum of 50-60 grams per sample. If seeking to execute entire workflow design ~120 grams of starting intact material is required. Exception is SS permeameter. Only intact analysis applies.

Nuclear Magnetic Resonance

The NMR itself only measures the total fluid volume per mass of the sample. (1) If the sample is in irregular shape, bulk volume (or bulk density) measurement is required before generating volumetric data (i.e., NMR fluid porosity), (2) If the sample is cylindrical, we can use caliper to measure the bulk volume, which is usually less accurate than bulk volume from Archimedes method. Hence, the combination of NMR and bulk density is recommended, unless laboratory data (cc/g) is acceptable. Nuclear magnetic resonance measurement at low-frequency with defined inter-echo spacing for T1T2 or only T2 acquisition. Fluid-filled storage volume quantified. Can be used for fluid typing as well as extraction efficiency understanding.

Can be performed on intact or crushed rock volume. Ideally a minimum of 50-60 grams per sample. If seeking to execute entire workflow design ~120 grams of starting intact material is required. Exception is SS permeameter. Only intact analysis applies.
