Notes |
|---|---|---|
|
AbsoluteDensity |
MassPerVolumeMeasure |
The density the material would have if no intra-granular porosity is present. (e.g. Boyle’s Law porosimetry). |
|
AcidSolubility |
MassPerMassMeasure |
The solubility of a proppant in 12:3 HCl:HF for 30 minutes at 150°F is an indication of the amount of soluble materials (i.e. carbonates, feldspars, iron oxides, clays, etc) present in the proppant. |
|
ApparentDensity |
MassPerVolumeMeasure |
Apparent density excludes extra-granular porosity by placing a known mass in a volume of fluid and determining how much of the fluid is displaced (Archimedes). |
|
BulkDensity |
MassPerVolumeMeasure |
Bulk density includes both the proppant and the porosity. This is measured by filling a known volume with dry proppant and measuring the weight. |
|
ClustersPercent |
DimensionlessMeasure |
Percentage of undesirable agglomerated discrete proppant particles which typically occurs more with inefficiently processed natural sand proppants as opposed to manufactured ceramic proppants. ISO 13503-2 and API RP19C limit the mass of clusters to less than 1%. |
|
KValue |
double |
Crush test classification indicating the highest stress level at which a proppant generated no more than 10% crushed material rounded down to the nearest 1,000 psi during a crush test. For example, a value of 14 means ‘14K’ which is 14000 psi. |
|
LossOnIgnition |
DimensionlessMeasure |
A mass loss (gravimetric) test method applied to coated proppants only, which determines the mass of resin coating applied to a natural sand or manufactured proppant by means of thorough combustion of the flammable resin from the nonflammable proppant. Reported as a % of original mass. |
|
MeanParticleDiameter |
LengthMeasure |
The mean diameter of particles in a sample of proppant. |
|
MedianParticleDiameter |
LengthMeasure |
The median diameter of particles in a sample of proppant. |
|
Roundness |
double |
Krumbein Roundness Shape Factor that is a measure of the relative sharpness of grain corners or of grain curvature. Krumbein and Sloss (1963) are the most widely used method of determining shape factors. |
|
SpecificGravity |
double |
Not formally part of ISO 13503.2 properties, the specific gravity is the apparent density of the proppant divided by the density of water. |
|
Sphericity |
double |
Krumbein Sphericity Shape Factor that is a measure of how closely a proppant particle approaches the shape of a sphere. Krumbein and Sloss (1963) are the most widely used method of determining shape factors. |
|
Turbidity |
double |
A measure of water clarity, how much the material suspended in water decreases the passage of light through the water. Unit of measure may be Nephelometric Turbidity Unit (NTU), but may vary based upon the detector geometry. |
