.... Conventional wisdom will attribute these fast relaxation components to the presence of bound water. However the comparison between the amount of free water quantified by thermogravimetric analysis and the NMR porosity detected at TE = 0.2 ms (Figure 4) shows that only a fraction of the total free water...

... as a linear combination of the individual T2 distributions of various poro-fluids (or factors) and a noise term as shown in Fig. 2. The identification of the fluid factors as clay bound water, capillary bound water, free water, oil, gas, and mud filtrate is still required. The premise is, if the NMR T2 log...

The results of extensive laboratory experiments, described in this paper, show that the use of two cementation exponents to characterize electrical behavior in shaly sand...

..., we generate a synthetic RD2D distribution containing free water, capillary bound water, light oil, and some heavy oil components. The intensity of each component in the RD2D map has a Gaussian shape. The contour of the final RD2D distribution is shown in Figure 2. The free water is at T2=10 3 ms...

.... PSXO= Swirr). However, in the water leg and the transition zone, the tool appears to be detecting both bound and some (undisplaced) free water (i. e. PSXO > Swirr). This difference is believed to be the result of variations in the invasion profile with changing water saturation. The PSX0 from...

It is called free water only to distin- guish it from bound water, and is not meant to imply producibility (the free water includes the formation irreducible water). ~ Mark of Schlumberger. -2...
