    摘要: Disclosed are a method and system for developing customized bound water transformations to obtain accurate determinations of non-producible water from nuclear magnetic resonance (NMR) logs. The approaches of this invention can be applied for in situ calibration where laboratory NMR measurements may not be possible or practical. In particular, a transformation model directly linking BVI and capillary pressure is developed by calibrating NMR derived BVI with the core data, the novel transformation model utilizes SBVI and/or CBVI models to directly relate NMR derived BVI and capillary pressure responses through the height of the measurement in a borehole. The derived height-based BVI transformation model is applied to the NMR log of the borehole to quantify non-producible water in the NMR log.

    摘要: A resonating electroplating anode electrode for electroplating the inside surfaces of steam generator tubing. The resonating electroplating anode electrode is formed from a plurality of tubular ceramic resonating material pieces glued to the inside and/or to one end of an anode tube to create a single resonating volume. In operation, an electrolyte solution is fed to the outside of the electrode in an annulus formed between the steam generator tube and the anode and returns through a hollow center in the anode. During use, the resonating materials resonate within the electrolyte solution during the electroplating process, thus creating an ultrasound enhanced-electroplating process. As a result, the resonating electroplating anode electrode and the resulting process reduce the amount of time required for electroplating, increase the production rate, reduce the residual internal stress resulting from electroplating, improves ductility and reduce brittleness of electrode-deposited nickel, produce a less porous deposited plating layer which improves corrosion resistance, and improve the uniformity of the electroplating coating grains. The resulting plated generator tubing is of superior quality and extended durability relative to currently known techniques.

    摘要: A method and apparatus for determining the presence of at least one naturally radioactive element in an earth formation surrounding a borehole, wherein, for each depth in the borehole, a spectrum is made of the gamma rays detected in several energy channels, and expressed as U=S Y, where "Y" is the elemental yields and "S" is a composite spectra matrix made of individual standard spectra characteristic of a given borehole environment; yields Y are then calculated. One thus determines a borehole correction factor from the general relationship between the borehole parameters, the standard spectra and the measured spectra. Finally, the yields are corrected for borehole effects by applying the correction factor.The correction factor is energy independent, at least for energies above a given threshold, and is also independent from the radioactive elements.
