Abstract
A method for nuclear magnetic resonance (NMR) logging is disclosed that pulses, using a quadrature antenna of an NMR logging tool in a borehole, a circularly polarized (CP) signal into a formation surrounding the borehole. The method also pulses, using the quadrature antenna, a reverse circularly polarized (RCP) signal into the formation. A sensor of the NMR logging tool detects a first NMR signal from the formation in response to the RCP pulses and a second NMR signal from the formation in response to the CP pulses. A correct transverse magnetization value is then recovered based, at least in part, on the first NMR signal and the second NMR signal.
