Production of seismic (artificial) signals on land (surface or water) or in water, receiving signals after traveling through the earth`s interior and recording (digital) of these signals for further analysis. There are a number of data collection techniques used to produce seismic profiles, all of which include measuring acoustic waves using a source and receiver. These techniques can continue to be categorized according to the configuration and type of sources and recipients used. For example, zero-offset vertical seismic profiling (ZVSP), passable VSP, etc. Reflection Leesismik is similar to the “Echo-in-the-Well” experiment, calculating the depth of the geological boundary from the two-way travel time (TWT) of the seismic signal and its velocity. The `-p` transformation is a particular case of radon transformation and is easier to apply than Fourier`s transformation. It allows to study different wave modes according to their slowness values, p-Displaystyle p.  The application of this transformation consists of adding (stacking) all traces in a data set along an inclination (oblique), which leads to a single track sequence (the so-called p value, slowness or ray parameters). It transforms the entry data from the space-time domain to intercept the field of slow time. Multichannel filters can be applied to each data set or the final seismic profile.
This can be done to separate different types of waves and improve the signal-to-noise ratio. There are two well-known methods for designing speed filters for seismic processing applications.  The `-p conversion converts seismic records into an area where all these events are separated. In simple terms, each point in the `-p domain is the sum of all the points in the x-t level that lie above a straight line with a p tilt and intercept.  It also means that a dot in the x-t domain turns into an online in the “-p” domain, turns hyperbolae into ellipses, and so on. As with Fourier`s transformation, a signal in the “-p” domain can be converted to the x-t domain.
