Wave-field visualization and interpretation visualization

Enables you to change and view synthetic gathers and wave field snapshots (calculated by the computation engine), as well as customize displays and to convert results into other formats.

The interpreter has the following options:

•Easy to adjust the range of amplitude values, amplify weak signals and to apply smoothing procedures.

•View snapshots individually or in animated fashion, making it easy to identify the flow of seismic events.

•Analyze different components of a wave field, such as pressureand instantaneous velocities of the particles' motion.

•Various display methods may be used (black-and-white or color palette, variable area, wiggle and variable density, reversed polarity, etc)

Additional transformations of the data is possible through the visual analyzer, some example are: Balancing of zero, Linear gain, various forms of Normalization, AGC, random noise addition, Casual shift, Smoothing, etc.

Visual analyzer and interpretation

In conditions of complex-geological media, the recognition of the wave's type on the modeled gathers is of great value. In the Tesseral software package this problem is addressed by analyzing wave field slices made in several fixed moments of time (time slices). Such slices can be visualized in either wave field X and Z components of the velocity vector of the particles' motion in the medium. This allows to easily distinguish transmitted and reflected waves of various types.

Salt core model example: Both the Reflected wave from the wall of the salt core and the complex duplex wave (double reflection from the wall and from the adjacent boundaries of the salt core) can be easily identified. Time sections were obtained by shooting from the same shot point. The Primary wave is shown by a red arrow, the reflected from the wall of the salt core converted wave is shown in blue, and shown in yellow the double reflected wave can be tracked from the moment of origin until its arrival to the surface. Underlying model boundaries are shown in the time section's snapshots.
