is the interactive tool, GeoWZ allows to load and to interpret upholes ,to trace first breaks on weathering shots, to interpolate surfaces after interpretation, to build layered models using built and loaded elevation and velocity surfaces, to calculate static corrections and to export models for further update in GeoStaR and other tools.

Data are loaded from the files, tables or traces headers, filled by geometry of sources/receivers, first breaks; Excel tables, LAS- and text files with upholes.

Data loading is a three stages process which consists of data reading, its control and final loading.

Interpretation is performed using display of the "CP Interpretation" diagram. All upholes which fall inside defined search radius are displayed here along with layer border markers and interval velocities. The interpretation can be performed either graphically, by moving horizon markers along uphole curve (tabulated values are updated automatically) either by editing of layers' depths and velocities in the table(the display is ). The results of the interpretation can be saved into control points file to re-used for model building in GeoStaR.

The interpreted layers' depths and velocities are used to interpolate surfaces.Each surface represent one mono-valued function (thickness, elevation or velocity of defined layer). The set of interpreted curves and interpolation parameters can be adjusted for each surface independently of each other. But the many curves can be built and updated at the same time.

In the case of any uphole re-interpretation, all surfaces (and models built using such surfaces) are updated automatically.

There are some surface operations implemented : smoothing, filling with defined value, re-interpolation inside or outside of a defined polygon, or of whole surface. It is possible to perform mathematical operations on or apply simple mathematical functions to surfaces.

Each model is the set of pairs of velocity and either elevation or thickness surfaces for each layer. Some "weight" can be defined for layer in order to resolve intersection conflicts.

It is possible to use different information displays: maps, sections, graphs, tables, gathers for data and models QC at any stage of work

There are three possible methods of calculation of statics: on the base geological model, on pseudo-datum or on the floating pseudo-datum.
