... component shifted to later times. We propose that the fixed T2 component is characteristic of the clay-bound water, while the slower T2 mode represents discrete water phase in the inter-aggregate clay pores whose volume increases as the water content increases. This paper establishes the T2 characteristics...

Simultaneous measurements of the swelling of the sample were used to calculate water content changes at the same three positions. The mineralogical composition of the shales...

... be observed at zero gap, and g is the gap. The parameters Ko and K1 are dependent on both water (ie. hydrogen) content and bulk density. In many situations failure to correct the count rate for this gap effect can result in a significant degradation in the accuracy of the water content calculated from...

... ABSTRACT We have studied four sources of error (uncertainty)in water content obtained from neutron logs calibrated in partially saturated media for holes up to 3 m. For this calibration we built a special facility and developed an algorithm for a commercial epithermal neutron log that obtains...

... ABSTRACT An epithermal neutron logging sonde has been calibrated in a facility containing nine samples. Each sample represents a different combination of bulk density and water content. The facility simulates very large (approx. 2-m-diameter)dry holes and 30-cm-diameterdry and water-filled...
