CODING OF SIMULTANEOUS SOURCES AND SEPARATION OF SOURCES AS PRACTICAL SOLUTION FOR FULL WAVE FIELD INVERSION Russian patent published in 2016 - IPC G01V1/28 G06F17/10 

Abstract RU 2582480 C2

FIELD: geophysics.

SUBSTANCE: invention can be used in processing seismic data. Disclosed is a method for simultaneous inversion of seismogram full wave field encoded from sources (or receivers) of geophysical data to determine model (118) of physical properties for geological medium, in particular, suitable for observation, in which conditions of stationary receivers geometry during data detection are not satisfied. Separation (104) of simultaneous sources is performed in order to reduce the effect of non-conformity of measured geophysical data with assumption relative to stationary receivers. Data processing step (106) carried out after separation of simultaneous sources is configured to match data calculated according to model (105) with measured geophysical data (108) for combination of sources and receivers which are absent in measured geophysical data.

EFFECT: high accuracy and reliability of obtained data.
