WinSism run under Windows 32 and 64

WinSism is your Windows solutions to process Seismic refraction. The software is user friendly and can be used very intuitively.


 With WinSism you can display SEG-2, SEG-Y, ABEM, OYO, PASI and Geometrics records. first break picking is very easy and precise on the screen. On screen corrections are possible for FBP.


After your enter field geometry, travel time assembly takes few seconds and data can be corrected on a build-in spreadsheet. Shots and receivers can have any geometry and elevations. All data are recorded in an ASCII file  (maximum 200 receivers and 50 shots).









The main features of WinSism are:



For processing

·       Trace phantoming

·       True velocity

·       Velocity computation (regression fit)

·       Velocity computation (linear)

·       Interactive FBP

·       Easy geometry input



For computation


·       Intercept time method

·       Critical distance method

·       ABC/Delay method

·       GRM Method




For display and printing

·           Travel time with precise scale

·           Preview with zooming

·           WMF export of all plots

·           Color Seismic profile with depth

·           Computation results

·           Export to RAYFRACT, PLOTREFRA, SEISOPT

·           Field record and Travel Time display




WinSism allows all usual operations for refraction processing, graphically on the screen. A manual and many tags are available. WinSism checks all data inputs against errors. Default values are proposed. A manual with demo data, processing explanations and used formulas is provided with WinSism. W-GeoSoft USB key. It contains videos and PowerPoint explaining all processing steps





WinSism17 comes with an inversion module TomoTEA. The initial inversion velocity grid is the velocity grid provided by WinSism traditional processing and not arbitrary values. The inversion use up-to-date Eikonal / Frechet algorithm


The processing has 4 steps:


1- WinSism will prepare and record all necessary files: topographical data, first beaks, shots location.


2-The velocity grid must be smoothed



3- Last step, launch inversion process, change default values if required.


4-Display and arrange final section (axes, level, color scale)




No need of external software, easy to use, quick processing



Many utilities are provided:


Ray tracing



Travel time comparison



Residual times
