The article presents the results of the study of the effect of the non-simultaneous measurement of electrical and electromagnetic logging signals on the determination of the parameters of the geoelectric model by joint numerical inversion. The radial profile of the electrical resistivity is calculated for different times after drilling in the program for modeling the process of mud invasion into a porous permeable formation with parameters characteristic of the BS cretaceous reservoir. For this continuous resistivity profile electric log signals are calculated for the reservoir of unlimited thickness.
