Petrophysical interpretation of time-lapse electromagnetic sounding in wells

Terrigenous reservoirs are studied by a joint analysis of processes of various physical nature. This study is urgent because new methods for formation evaluation (first of all, permeability) from electric and electromagnetic logging data are required. We propose a method for the complex processing and interpretation of time-lapse well logging electromagnetic measurements, which show the dynamics of processes in the well influence zone. The constructed electrohydrodynamic model of the borehole environment is used to estimate the hydrophysical (petrophysical) parameters of the formation.
