2D Modeling
It uses background pictures and Txt file with prescribed form or create 2D model. The time and depth model can be directly established, the time model can be converted to depth model, the depth model generates grid model. The model description algorithm is advanced in support of the rolling surface.
Main functions: model building, model editing, time-depth conversion, grid model.

Geometry Definition
According to the actual situation in the field acquisition, the shot and geophone layout in 2D model surface or underground is convenient for model analysis. You can define various complex geometry systems, SPS data input and output. Main functions are: conventional acquisition, VSP, reverse VSP, borehole seismic.

Parameter Argument

It analyzes the migration border, resolution analysis, NMO stretching, attenuation, DMO analysis, comprehensive parameter analysis, which provides a scientific basis for geophysicists to design the seismic acquisition geometry system. Main functions are: resolution, bin size, array length, attenuation, DMO, seisline offset.

Ray Tracing

It has advanced tracing algorithm to support multi-path tracking with rich and comprehensive analysis contents. Main functions are: reflection wave, refraction wave, direct wave, converted wave, diffraction wave, self-excited and self-closing and the ray applications including vertical ray, image-ray function, wavefront analysis, time-distance curve, CRP fold, etc.

Lighting Analysis
Seismic waves by artificial stimulation propagate to interface and reflect to the receiver, the reflected light energy by the receiver is equivalent to the interface lighting value. By lighting analysis, we found the model energy distribution rule, which laid geometry system in a targeted manner to avoid the exploration risk. This software provides one-way lighting and two-way lighting methods. Main functions are: single-shot lighting, plane wave lighting, application geometry lighting and the analysis comparison for different lighting results.
