Abstract: An earthing card emits energy tuned to the natural frequency of the Earth. The card may include a material, carbon fiber or other substrate, programmed using scalar waves. Information is embedded into the carbon fiber via a system that uses a wave function generator to produce resonant frequencies for the application and drive wave information from a transmitting electrode to a receiving electrode. The scalar waves between the electrodes may be subjected to a wave or field source modulating the resultant wave information received at the receiving electrode. A material placed on a receiving coil at the receiving electrode receives the resultant wave information programming the material to emit energy tuned to the natural frequencies of the Earth. By placing the card on the body or running water over the card and spraying the body, the body will receive the energetic information emitted by the programmed material.

Abstract: In multi-echo imaging, in imaging in which pulses other than a 180° pulse are included in refocus RF pulses, a high-quality image in which the intended contrast is emphasized is obtained by reducing unnecessary contrast. Therefore, imaging parameters are adjusted so as to reduce the unnecessary contrast. The adjustment is performed so that, for echo signals from tissues having the same relaxation time to cause intended contrast among echo signals from a plurality of tissues having different relaxation times, the difference between the signal strengths of echo signals to determine the contrast, such as echo signals at the k-space center, is reduced. Imaging parameters to be adjusted include a repetition time, the FA of a DE pulse, the FA of a saturation pulse, the application timing of the saturation pulse, the application strength of a gradient magnetic field in a recovery period, application timing, and the like.

Abstract: Downhole fluid volumes of a geological formation may be estimated using nuclear magnetic resonance (NMR) measurements, even in organic shale reservoirs. Multi-dimensional NMR measurements, such as two-dimensional NMR measurements and/or, in some cases, one or more well-logging measurements relating to total organic carbon may be used to estimate downhole fluid volumes of hydrocarbons such as bitumen, light hydrocarbon, kerogen, and/or water. Having identified the fluid volumes in this manner or any other suitable manner from the NMR measurements, a reservoir producibility index (RPI) may be generated. The downhole fluid volumes and/or the RPI may be output on a well log to enable an operator to make operational and strategic decisions for well production.
