Reflex2DQuick

The program Reflex 2D-Quick allows an easy import, display, processing and interpretation of 2-dimensional GroundPenetratingRadar zero offset and seismic single shot data (click on the datatype for a video guide) . The program is free for Reflexw 2D-dataanalysis users but it can also be ordered as a lowcost standalone processing tool. The program offers the following possibilities:

direct import from different formats like SEGY, SEG2, DZT, RD3, DZT, DT1,HDR, DT, JPRB, Reflexw
easy change of distance scaling and geometry
standard processing with the following possibilities

subtract DC-shift and subtract mean (dewow)
static correction and correct topography
time cut and compress
gain function
bandpass butterworth
background removal
running and subtracting average
fk migration
XFlipProfile
extract datapart

different display possibilit8es like point or wiggle mode, scaling and zooming functions
The data may be exported to the clipboard or saved as ASCII- or bitmap-data and to other formats like SEGY, SEG2
Printing is possible with freely choosable scale either in cm or scale like 1:1000 with a print preview menu which allows to preview the size and shape of the print output and to define an individiual print header.
interactive velocity adaptation for zero-offset, single shot (reflection and refraction) or VSP data

It is possible to adapt diffractions, reflections and straight lines. You may change the velocity, the radius of the target, the angle between the line and the target and the width of the calculated diffraction or reflection hyperbola. There is also the possibility of fitting linear features either by changing interactively a line or by setting two points. The option core allows to vary interactively the velocities of the single layers of the individual cores stored within an ASCII-file. In addition an interactive use of the intercept time method for seismic refraction data is included (see picture on the right). The option enables to get a first 1D-model very quickly.

picking the onsets and combine the picked phases to layer model

You have the choice between manual picking, continuous picking and a semi-automatic picking using a phase follower (manual editing is always possible). It is possible to export the picks into an ASCII-format together with the 3 space coordinates for a subsequent interpretation.
The so called layer-show offers the possibility to combine individual pick files, to plot them together with the wiggle-files and to output them in report form on printer or file containing the depths, velocities and amplitudes of the individual layers. The time-depth conversion of the picks is either based on mean or layer velocities

Crosshole Seismic Testing add on module

In this method, also known as Crosshole Sonic Logging (CSL), the source (p- or s-wave source) and the receiver are located at the same depth within two separate boreholes. The traveltimes of the first arrivals are transformed into p- and or s-velocities which represent average values between the boreholes. A multi-directional receiver array is supported. The deviation of the boreholes (true xyz-coordinates) can be taken into account. The picking of the first arrivals can be done by different automatic methods or manually or by a combination of both. If a shear wave source with 2 different orientations has been used the raw data can be overlaid for a more accurate picking. The result of the interpretation is a 1-dimensional velocity distribution.
