Abstract (en)
[origin: WO2018164884A1] Data obtained with an electromagnetic energy transmitter in borehole to surface electromagnetic (BSEM) transmitter is processed to determine a detected electromagnetic field between the transmitter and a receiver array. The processed data provides measures of detected electromagnetic fields, induced polarization and electromagnetic well logging information of interest for surveying and mapping of subsurface formations.
