3D SEISMOTOMOGRAPHY INTERPRETATION (REFRACTED WAVES). The ZondST3d program is designed for 3D processing and interpretation of refracted wave seismic tomography and CMSL data in surface (area), interwell and offshore versions. The term seismic tomography entered geophysical terminology a long time ago. This is due to the fact that one of the main tasks of seismics is inverse kinematics. It consists in determining the speed characteristics of the medium under examination starting from the known travel times of the refracted waves from the point of excitation of the signal to the point of its recording. That is, kinematic seismic tomography uses the travel times of seismic waves to reconstruct structures within the earth, which appear as variations in seismic velocities. Cross-well seismic tomography has received the greatest popularity in engineering geophysics. This direction is used for a detailed study of the structure of the rock mass in the space between the wells. The 3D seismic tomography technique involves a special measurement technique that uses a large number of source and receiver locations, with the number of seismic traces reaching tens of thousands. But in many cases, for a three-dimensional interpretation, it is sufficient to use the two-dimensional seismic tomography results obtained on several parallel profiles. ZondST3d provides a turnkey seismic tomography solution and solves a wide range of tasks, from mathematical modeling and sensitivity analysis, to field data processing and interpretation. A user-friendly interface and a wide range of data presentation options allow you to solve the set geological problem as efficiently as possible.
