Abstract

The Multifocusing Technology (MT) – modern seismic data processing method – has a lot of outstanding properties in comparison with the conventional seismic processing. This method allows to collecting and enhancing useful waves; no knowledge about the velocity structure of the overburden is required for correlation and stacking; and stacking the data degrades neither the resolution of nor the information about the target objects. Implementation of the MT,
developed on the basis of Homeomorphic Imaging theory, utilizes a phase correlation of the signal on the observed seismic traces. The data are moveout corrected along different travel time curves to find the curve closest to the travel time curve of the signal. Analyses of MT time sections permits to revealing some stratigraphic peculiarities not reflected in time sections obtained using conventional seismic packages. Integration of MT with potential field analysis increases reliability and precision of physical-geological models. For advanced analysis of potential fields has been developed a set of procedures including algorithms for revealing of useful signals against the noise background, qualitative and quantitative interpretation of potential field anomalies observed in complex environments as well as 3-D combined modeling of gravity and magnetic fields. MT – potential field integration was applied for re-interpreting of geological-geophysical sections in Heletz Oil field (central Israel). On the basis of mutual analysis were revealed unknown characteristics of medium used for subsequent drilling substantiation.
