The program uses soВ called WET or Wave Eikonal Traveltime tomographyВ processing (formula for the back projection of traveltime residualsВ in traveltime tomography). The tomographyВ inversion is performed with the softwareВ RAYFRACT. Quality control of geological models is performed byВ direct graphical comparison of the measured travel time data to thoseВ calculated from the model solution. ItВ handles several real life geological situations, such as discontinuities velocityВ distributions and sharp vertical or horizontal velocity gradients caused byВ e.g. Wave propagation is modeled in a physically meaningful way with rayВ paths, using the output from the Delta-TV inversion as starting model. WET or Wave Eikonal Traveltime Tomography Processing It is especially a veryВ strong tool for structural interpretation of the geologic situation.Дў. The method handlesВ real life geological situations such as velocity gradients / linear increasingВ of velocity with depth / velocity inversions / pinching out layers and outcropsВ / faults and local velocity anomalies gracefully.

The Delta TV method is a pseudo 2D Inversion method that delivers a continuousВ 1D velocity versus depth model for all geophone stations. The program basically offers twoВ different ways of processing the data:ДЎ.DELTA-TVВ method, GebrandeВ and Miller (1985)

The softwareВ RAYFRACTВ is a windows based 32-bits software packageВ for processing of refraction seismic data. The program uses soВ called WET or Wave Eikonal Traveltime TomographyВ processing. Deformation zones may have a narrow core of heavilyВ crushed rocks, but they are often surrounded by a wider zone (influence area)В constituting altered, fractured rocks with deteriorated mechanical propertiesВ as compared to the fresh rock.В In order to extractВ more information from the seismic data as compared to the traditionalВ processing technique, to overcome the limitations of the standard refractionВ seismic technique and to be able to create more advanced geological modelsВ (more diverse bedrock velocity models) that come closer to the complex reality,В the data are processed by use of modern computerized tools for analyzingВ refraction seismic data with tomography inversion techniques. The real case is mostВ likely much more complex. The traditionalВ technique for processing and interpretation of refraction seismic data (see StandardВ Refraction Seismics) often results in geological models which show disturbedВ subsoil areas (deformations, weak zones, discontinuities, faults, etc.) as aВ thin sharp low velocity zone surrounded by fresh rock.
