Abstract:
An apparatus for estimating a nuclear magnetic resonance (NMR) property of an earth formation penetrated by a borehole, the apparatus including: a logging tool having a source of a static magnetic field configured to polarize a region of investigation in the earth formation; a transmitter antenna disposed at the logging tool and configured to transmit electromagnetic energy into the region of investigation; at least one receiver sensor disposed at the logging tool and configured to receive NMR signals from the region of investigation in response to an interaction between the static magnetic field and the transmitted electromagnetic energy; and a processor configured to: receive the NMR signals from the at least one receiver sensor; associate the NMR signals received from the at least one receiver sensor with an azimuthal direction at which the NMR signals were received; and estimate the property from the NMR signals and the associated azimuthal directions.
