Gardner's relation¶
Gardner, is an empirically derived equation that relates seismic P-wave velocity to the bulk density of the lithology in which the wave travels.
Core Idea¶
Gardner's relation is treated here as the recurring naturalsciencesengineeringhealth identity summarized by this source-grounded definition: Gardner, is an empirically derived equation that relates seismic P-wave velocity to the bulk density of the lithology in which the wave travels. Gardner's relation, or Gardner's equation, named after Gerald H. Gardner, is an empirically derived equation that relates seismic P-wave velocity to the bulk density of the lithology in which the wave travels. where \rho is bulk density given in g/cm 3 , Vp is P-wave velocity given in ft/s, and \alpha and \beta are empirically derived.
Scope of Application¶
-
Documented setting. Gardner, is an empirically derived equation that relates seismic P-wave velocity to the bulk density of the lithology in which the wave travels.
-
Documented setting. where \rho is bulk density given in g/cm 3 , Vp is P-wave velocity given in ft/s, and \alpha and \beta are empirically derived constants that depend on the geology.
-
Documented setting. Gardner et al. proposed that one can obtain a good fit by taking \alpha = 0.23 and \beta = 0.25 .
-
Documented setting. If Vp is measured in m/s, \alpha = 0.31 and the equation is.
-
Documented setting. This equation is very popular in petroleum exploration because it can provide information about the lithology from interval velocities obtained from seismic data.
Clarity¶
A clear use of Gardner's relation names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is Gardner, is an empirically derived equation that relates seismic P-wave velocity to the bulk density of the lithology in which the wave travels.
Manages Complexity¶
Gardner's relation compresses multiple naturalsciencesengineeringhealth details into a stable diagnostic relation. The source shows both the central mechanism—gardner, is an empirically derived equation that relates seismic P-wave velocity to the bulk density of the lithology in which the wave travels.—and the practical consequence—the constants \alpha and \beta are usually calibrated from sonic and density well log information but in the absence of these, Gardner's constants are a.
Abstract Reasoning¶
- Type the carrier. Identify the naturalsciencesengineeringhealth entities to which the claim applies.
- State the relation. Use the source-grounded identity: Gardner, is an empirically derived equation that relates seismic P-wave velocity to the bulk density of the lithology in which the wave travels.
- Check operation and conditions. where \rho is bulk density given in g/cm 3 , Vp is P-wave velocity given in ft/s, and \alpha and \beta are empirically derived constants that depend on the geology.
- Demand recognition evidence.
Knowledge Transfer¶
Within the home domain. Knowledge about Gardner's relation transfers literally when a new case preserves the same carrier type, relation, and recognition test. Gardner, is an empirically derived equation that relates seismic P-wave velocity to the bulk density of the lithology in which the wave travels. where \rho is bulk density given in g/cm 3 , Vp is P-wave velocity given in ft/s, and \alpha and \beta are empirically derived constants that depend on the geology. Beyond the home domain. No canonical parent is asserted for Gardner's relation.
Neighborhood in Abstraction Space¶
Gardner's relation sits in a moderately populated region (58th percentile for distinctiveness): it has near-neighbors but no dense thicket of look-alikes.
