Patent ID: 8324895

Claim:
An apparatus for estimating a property of an earth formation penetrated by a borehole, the apparatus comprising: a logging tool; a source of a static magnetic field, the source being disposed at the logging tool and configured to polarize a region of investigation; a transmitter antenna disposed at the logging tool and configured to transmit a train of pulses of electromagnetic energy into the region of investigation; a plurality of receiver antennas disposed at the logging tool and configured to receive nuclear magnetic resonance (NMR) signals from a plurality of angular segments in the region of investigation in response to an interaction between the static magnetic field and the pulses of electromagnetic energy; and a processor configured to: receive the NMR signals from each receiver antenna, the NMR signals comprising first NMR signals received from an angular segment by one receiver antenna and second NMR signals received from the angular segment by at least two receiver antennas; associate the first NMR signals and the second NMR signals with the angular segment from which the first NMR signals and the second NMR signals were obtained; deconvolve the second NMR signals to produce deconvolved NMR signals; and estimate the property from the first NMR signals, the deconvolved NMR signals, and the associated angular segments.
