Summary This paper discusses a new nuclear magnetic resonance (NMR) method that can provide wettability, saturation, and oil viscosity values in rocks partially saturated with oil and brine. The method takes advantage of two new technological advance

The distribution function between diffusion and spin relaxation time is shown to be a powerful tool to characterize fluid mixtures in porous media. We discuss the nuclear magnetic resonance measurements using diffusion-editing sequences that were dev

Summary Very thin, laminated sand-shale sequences pose a challenge to petrophysical evaluation. The poor vertical resolution of the log measurements results in pessimistic estimates of hydrocarbon volumes and producibility. An earlier proposal by Fla

Measurements of time-dependent diffusion are performed on a rock sample saturated first with water, then methane and finally ethane. The gases were selected because their increased diffusivities and relaxation times allow probing greater length scale

Summary A theoretical and experimental effort to understand the effects of borehole rugosity on individual detector responses yielded an improved method of processing compensated density logs. Historically, the spine/ribs technique for obtaining bore

We present diffusion-relaxation distribution functions measured on four rock cores that were prepared in a succession of different saturation states of brine and crude oil. The measurements were performed in a static gradient field at a Larmor freque

[1] Proton nuclear magnetic resonance (NMR) of liquid water can be used to indirectly detect and assay methane hydrate in opaque earth materials. It is also potentially useful for quantifying pore size control of hydrate formation, and for estimating

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 decr
