Abstract

The CMR* Combinable Magnetic Resonance logging tool has been upgraded to provide a robust measurement of clay bound water and microporosity. The upgraded measurement is now possible because of a 50% increase in the signal-to-noise (SIN) ratio, a decrease in the minimum echo spacing from 0.32 ms to 0.2 ms and improved signal processing software that has maximum sensitivity to fast decays. The new CMR hardware and signal processing software reduce the transverse relaxation time (T2) sensmvity limit (minimum detectable T2) of the measurement for depth logging from 3 ms to 0.3 ms.
