Instantaneous attributes
Nettet6. mai 2024 · In the original sense, an instantaneous attribute is a quantity derived from what is called complex-signal analysis or complex-trace analysis. A conventional … Nettet28. jul. 2015 · All instantaneous seismic attributes (amplitude, phase, frequency) can be used in interpretation. In practice, most interpreters use instantaneous amplitude, or some variation of an amplitude attribute, as their primary diagnostic tool. Amplitude is related to reflectivity, which in turn is related to subsurface impedance contrasts.

NettetInstantaneous Attribute can be used quickly and accurately to pick seismic events (or sequence boundaries) regardless of amplitude changes. Delineating Karst features using Advanced Interpretation 4 Fig4: Boonsville (Trace … NettetInitially, 18 instantaneous attributes, 14 coherency/similarity attributes, 10 curvature attributes, and 40 frequency subband volumes of spectral decomposition were generated. In the evaluation of these seismic attributes, it was determined in the Eagle Ford interval that the highest energy resided in the 22- to 26-Hz range.
Nettet1. mar. 1993 · Instantaneous bandwidth is observed to be nearly always less than instantaneous frequency; the points where it is larger may mark the onset of distinct wavelets. These attributes, together with instantaneous frequency, are perhaps of greater use in revealing the time-varying spectral properties of seismic data. Nettet1. apr. 2010 · 4.1.3.1 General Structure. Phase signals (PSs) are the basic elements of phase or frequency modulation and this shows their importance. They are real signals with constant instantaneous amplitude. They are characterized by a canonical pair [1, ϕ (t )] or by a unique function ϕ ( t) such that exp [ j ϕ ( t )] is an AS.
NettetInitially, 20 instantaneous seismic attributes were run through a PCA analysis in a zone 20ms above and 150 ms below the top of the mapped producing reservoir. Based on these PCA results, various combinations of attributes were employed in different SOM analyses with neuron counts from 3X3, 5X5, 8X8, 10X10, and 12X12 employed for each set of … Nettet27. sep. 2024 · Several intriguing methods purportedly achieve subseismic resolution through instantaneous attributes. Chief amongst these is the thin bed indicator …
NettetInstantaneous Amplitude: Also known as the Envelope. It is the magnitude of each pair of polar values produced by applying a Hilbert transformation to the original seismic trace …
