摘要： A typical nuclear well logging tool forms a count rate data stream including statistical noise. A robust single pass partially deconvolved smoothing filter matched to the tool response is applied to the count rate data to enhance vertical resolution while minimizing the statistical noise increase. The smoothing filter is partially deconvolved by the application of a three point deconvolution characteristic of the cusp portion of a related cusp function and a box function representative of the tool response.

摘要： A method for calculating the position and quantity of scale downhole, while avoiding the need to run a before log is provided. The method includes assessing the gamma ray spectra of both scale and tracers in a single logging pass. A matrix of multipliers for both borehole and formation radium is included in the data used to evaluate the gamma ray log. The radium in the formation is distinguished from radium near the borehole (scale) using the deflection of the relative distance curve and the resulting calculations of gamma ray energy attributable to scale are used to correct the measured gamma ray emissions attributed to the tracers. The method allows several tracers to be monitored with a single logging pass, even in a hole that has been previously produced and has been contaminated with radioactive scale.

摘要： A system for use in cased well boreholes for measuring gamma ray spectra induced by bombardment of earth formations in the vicinity of the borehole with fast neutrons. Monoenergetic fast neutrons emitted in repetitive pulses penetrate the borehole structure and enter earth formations in the vicinity of the borehole and are moderated by elastic and inelastic scattering to thermal energy and captured by the nuclei of elements in and about the borehole. A scintillation detector optically coupled to a photomultiplier detects gamma radiation induced by the neutrons and produces electrical pulses with amplitudes representative of the energy of gamma rays. A pulse height analyzer connected to the output of the detector and photomultiplier separates the electrical pulses into a spectrum representative of the gamma ray energy spectrum. A timing circuit generates time gate signals to separate the electrical pulses into those of fast neutron induced gamma rays, thermal neutron capture gamma rays, and background gamma rays prior to sending the pulses to the pulse height analyzer. The timing cycle has a fast subcycle in which pulses representative substantially only of fast neutron induced gamma rays and thermal neutron capture gamma rays are sent to the pulse height analyzer and a slow subcycle portion in which pulses substantially representative only of thermal neutron capture gamma rays and background gamma rays are sent to the pulse height analyzer.

摘要： A method for evaluating the penetration of downhole materials such as proppant, casing annulus fill, or packed gravel by radioactively tagging the material, conducting well logging with gamma ray spectroscopy equipment to generate data signals, and applying an improved low-noise processing routine to the data signals to determine the material's penetration diameter. After hydraulic fracturing, gravel packing, or cementing operations are performed on a cased well, the well is logged using gamma ray spectroscopy techniques. In an exemplary embodiment, the resultant data signals are divided into channels, sent uphole, consolidated into depth intervals, and summed into specified energy windows. The spectra are processed by a weighted least squares technique to represent the spectra as borehole and formation component signals. The relationship between the borehole and formation component signals, which may be expressed as a borehole-formation angle, is then applied to an empirically determined relationship between the borehole-formation angle and mean penetration diameter to provide a penetration diameter signal to assist in evaluating the distribution of the materials pumped downhole.
