Abstract
Methods and systems for estimating properties of earth formations including conveying a carrier through a borehole having a transmitter, a first receiver, and a second receiver, the first receiver positioned a first distance from the transmitter and the second receiver positioned a second distance therefrom, generating with the transmitter a transient electromagnetic field, receiving a first measured signal at the first receiver, receiving a second measured signal at the second receiver, obtaining a total signal from the first measured signal and the second measured signal, determining a bucking coefficient, performing a bucking calculation employing the bucking coefficient, the first measured signal, and the second measured signal to extract a pipe signal, suppressing the pipe signal from the total signal to obtain a formation signal, estimating a formation property from the formation signal, and adjusting a drilling operation based on the estimated property of the formation.
