The difference between Seismic Reflection and Refraction explained.

Image
Seismic Reflection and Seismic Refraction are the two geophysical techniques of active seismology. These seismic techniques measure the travel time of the acoustic seismic waves after they either reflect or refract from different material mediums. Also the fact that they utilize the same data acquisition instruments and tools ranging from seismic sources like sledge hammer, dynamite, to seismograph receivers like geophone and hydrophones still continue to pose questions regarding their differences. Despite this, similarity these two seismic techniques operate differently and objected to produce different results. And the fact that if you are not an expert in this field of geophysics it would be very challenging to make a clear distinction between these two seismic techniques. If you want to know these comparisons in clear and simplified way check and visit to Comparative Geophysics eBook . This post is intended to make  clear to  you the differences between seismic reflectio...

SEG-Y versus SEG-D seismic data Format explained

Image
In geophysical field surveying, data is collected and stored in various formats to simplify data processing and exchanging (data transfer). However in Seismic geophysics, It is recommended to collect seismic data in industry standard format so as to reduce ambiguity as most seismic data involves complex processing. There are two (2) industry standard formats for handling seismic data, SEG-D and SEG-Y. This post will give you an idea on these two format handle seismic data,  The great format is Industry - standard which was first developed in 1973, and published in 1975 by Society of Exploration Geophysicists (SEG). i/ SEG-D Format It stores acquired seismic field data either in multiplexed or demultiplexed form. We can say that it is raw data that was collected from geophysical sensors with no source applied. The seismic data is in unprocessed format and implies the original seismic data that was collected from the seismic recording system. This means a different traces will have ...

Concept of Hilbert transform explained

Image
It is obvious that in the field of mathematics the term Hilbert transform can be defined as a transform that takes a function of a real variable and produces another function of a real variable.  Concept of Hilbert transform The fast and easily way to grasp the concept regarding this transform is that, let's say we have the signal constructed by a cosine function, then we can extract the waveform of the sine function from our cosine function, simply create a sine wave out of cosine wave through the Hilbert transform. The Hilbert transform is important in signal processing , at which the analytic representation of a real-valued signal, say x(t) , is produced.  The Hilbert transform was first introduced by David Hilbert in 1905 for the purpose that a special case of the Riemann–Hilbert problem for analytic functions can be solved. The analytic signal produced by the Hilbert transform is useful in many signal analysis applications, while implementing the Hilbert transform enabl...
