CA 2594055

A method for determining a property of a substance in a downhole measurement region includes the following steps: providing a static magnetic field having a static magnetic field gradient in the measurement region; applying, in the measurement region, a pulse sequence that includes a tipping pulse, a re--focusing pulse, and a pulsed field gradient pulse train; wherein the pulsed field gradient pulse train includes a first portion and a second portion; the first portion comprising a first pulse or set of pulses having a first polarity and a second pulse or set of pulses having a second polarity, the second polarity being opposite to the first polarity, and wherein the first portion occurs before the re- focusing pulse; the second portion comprising a third pulse or set of pulses having the first polarity and a fourth pulse or set of pulses having the second polarity, and wherein the second portion occurs after the re-focusing pulse; and receiving one or more spin echoes from the measurement region.
