Hi, TDRs work for wireline ( time domain reflectometers ), but the magic # is the propogation velocity, wireline has not been characterized.. Insulation...
Todd, you're still kicking! Logging line is indeed complex to characterize. For lab work, we have constructed "dummy lines" using networks of resistors and...
Time Domaim Reflectometry (TDR) WILL provide a solution to this problem. Assuming you have access to both ends of the cable, you bounce a pulse from each end....
