摘要： Nuclear magnetic resonance (NMR) gas isotherm techniques to evaluate wettability of porous media, such as hydrocarbon reservoir rock, can include constructing a NMR gas isotherm curve for a porous media sample gas adsorption under various pressures. A hydrophobic or hydrophilic nature of the porous media sample can be determined using the NMR gas isotherm curves. A wettability of the porous media sample can be determined based on the NMR gas isotherm curve. The wettability can be determined for porous media samples with different pore sizes. In the case of reservoir rock samples, the determined wettability can be used, among other things, to model the hydrocarbon reservoir that includes such rock samples, to simulate fluid flow through such reservoirs, or to model enhanced hydrocarbon recovery from such reservoirs.

摘要： Re-usable ceramic magic angle spinning (MAS) NMR rotors constructed of high-mechanic strength ceramics are detailed that include a sample compartment that maintains high pressures up to at least about 200 atmospheres (atm) and high temperatures up to about least about 300° C. during operation. The rotor designs minimize pressure losses stemming from penetration over an extended period of time. The present invention makes possible a variety of in-situ high pressure, high temperature MAS NMR experiments not previously achieved in the prior art.

摘要： The present invention relates to a sample holder that can withstand high pressures and temperatures. In one embodiment, the sample holder of the present invention can be used to subject a geological sample to the same temperature and pressure that the sample would experience in its native underground environment. The present invention provides a mechanism for hydrostatically confining the rock core sample to simulate the below ground pressure, while simultaneously allowing fluid to be directed through the core, as needed. In various embodiments, the material used for the housing of the sample holder, specifically ceramic zirconia, and the mechanism by which the end fixtures are mounted in the housing, e.g., a square thread or modified square thread, allow for operation at higher pressures and temperatures than is offered by currently available systems. In one embodiment, the device of the present invention can be used to analyze rock core samples via NMR spectroscopy or MRI.

摘要： The present invention pertains to an apparatus and method for conducting magnetic resonance measurements on fluids at high pressures and/or high temperatures. The apparatus can be used in conjunction with or as part of a downhole fluid sampling tool to perform NMR measurements on fluids withdrawn from petroleum reservoirs, or can also be used for laboratory measurements on live reservoir fluids. The apparatus can perform all of the measurements made by modern NMR logging tools, including multi-dimensional distribution functions of spin-spin (T2) and spin-lattice relaxation (T1) times and molecular diffusion coefficients. The spin densities of hydrogen and other NMR sensitive species can be computed from the distribution functions. The apparatus can also be used to predict the apparent conductivity of the fluids in the flowline from measurements of the quality factor (“Q”) of the NMR circuit. The apparent conductivity can be used to predict water cut or water salinity.

摘要： Preparations of a highly coherent diamond nitrogen vacancy (NV−) and a diamond anvil are provided. A graphite is used as a carbon source, a diamond is used as a crystal seed, aluminum/titanium is used as a nitrogen remover, and a single crystal diamond is synthesized under a high temperature and a high pressure, and high-pressure-high-temperature (HPHT) annealing is performed on the synthesized diamond; after the annealing, multiple NV−s are generated in and crystal orientation growth regions from scratch, while native NV−s in a crystal orientation growth region are disappeared; and the and crystal orientation growth regions do not contain defects related to ferromagnetic elements. The high-density and highly coherent NV−s are produced under nondestructive conditions, and the diamond anvil with controlled NV− depths are prepared to achieve a precise detection of the NV− at a pressure above 60 GPa.

摘要： A device for the analysis of fluid distribution in an absorbent article is disclosed. The device provides for a frame, a pressure chamber disposed in contacting and mating engagement with the frame, and a NMR sensor in cooperative engagement with the frame and the pressure chamber. The pressure chamber further comprises a top plate and a conformable surface. The absorbent article is disposable between the top plate and the conformable surface. The NMR sensor is disposable proximate to the pressure chamber and is capable of measuring a fluid distribution in the absorbent article when the absorbent article is disposed between the top plate and the conformable surface of the pressure chamber and the NMR sensor is disposed proximate to a surface of the absorbent article.
