    Abstract: 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can be used in conjunction with or as part of a downhole fluid sampling tool to perform NMR measurements on fluids withdrawn from petroleum reservoirs, or can also be used for laboratory measurements on live reservoir fluids.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 (Ti) 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.

    Abstract: Featured are a device with localized sensitivity to magnetic resonance signals, an imaging system using such a device and MRI methods for performing internal MRI or MRI Endoscopy. Such an MRI method includes introducing an MRI antenna or probe into the specimen to be imaged, the antenna being configured in accordance with the devices described herein, so that the spatial coordinate frame of imaging is inherently locked or defined with respect to the introduced antenna thereby providing imaging of the specimen from the point of view of the antenna. Further such imaging is conducted so that the MRI signal is confined substantially to a volume with respect to a particular region of the antenna or probe.

    Abstract: A method and apparatus for Magnetic Resonance Imaging with specialized imaging coils possessing high Signal-to-Noise-Ratio (SNR). Imaging and/or Radio Frequency receiving coils include a ballistic electrical conductor such as carbon nanotubes, the ballistic electrical conductor having a resistance that does not increase significantly with length. Due to their enhanced SNR properties, system designs with smaller static magnetic field strength can be constructed for the same quality of imaging, leading to substantial reductions in system size and cost, as well as to enhanced imaging with existing MRI systems.

    Abstract: A magnetic resonance imaging system (10) includes a primary magnet and a secondary magnet operable to produce magnetic fields within a sample being imaged. The MRI system further includes at least one RF coil (50) that is operable to receive electromagnetic frequencies from the sample. The RF coil is formed from tubing (221) that serves as a cooling conduit through which flows a cooling fluid provided by a cooling source. The cooling fluid cools the RF coils to improve imaging of the sample.

    Abstract: The invention uses one inductor, which is comprised of one, two or few twisted or parallel conductors and exposes the sample in a pulsed and damped alternating magnetic field B without necessarily the employment of a second constant intensity magnetic field. In this way, the nuclei and the electrons of the sample-object are activated, in the presence of a non-constant magnetic field B that gets infinite negative and positive values between successive damped positive and negative values, crossing through the zero value during a magnetic pulse. Thus, a wide nuclear NMR and Electronic EPR Multiple - Resonance of sample, is achieved.
