摘要： An advanced method for determining formation density in an array-detector density tool uses three or more detectors to yield an improved accuracy and precision of the formation density measurement even in the presence of a large standoff between the tool and the formation. A more accurate photoelectric factor is determined through a new single detector algorithm. Use of the information on the photoelectric effect and the density from the three detectors allows the measurement of a photoelectric effect compensated for stand off and the photoelectric factor of the mudcake. The use of the multi-detector density answers allows for a consistency check and therefore a much improved quality control of the density measurement.

摘要： A method and an apparatus for decomposing a gamma spectrum representative of an unknown material for determining the contribution of each constituent postulated to constitute the material, wherein an energy spectrum of the gamma rays issued from the material is formed, as well as a composite spectrum made up of individual standard spectra of the postulated constituents and comprising elemental yields being representative of the proportion of the corresponding constituents; the best fit between the measured spectrum and the composite spectrum is determined by modifying simultaneously at least one elemental yield and at least one parameter representative of the conditions under which the measured spectrum and the composite spectrum have been obtained. The best fit may be based on any non linear least squares search for a global minimum of X.sup.2 =(S Y-U).sup.T W(S Y-U), where "U" is a matrix representing the measured spectrum, "S" is a matrix representing the composite spectrum, "Y" is a matrix representative of the elemental yields and "W" is a weight matrix. The non linear fitting method used may be e.g. a gradient search or the Marquardt method.

摘要： A apparatus and an apparatus for determining the respective contributions in spectroscopy measurements of the borehole and the earth formations surrounding the borehole, derived from the detection of gamma rays resulting from the collisions of neutrons with atoms of the formation or the borehole. From gamma rays from a near and far detector, and established, at each depth, responses (e.g. elemental yields) representative of the values of an unknown in the borehole and in the formation. The far detector response is plotted against the near detector response. From the plot and from known conditions of the detection, is derived a closed curve characteristic of the relative contributions of the borehole and the formation in the responses. For each depth, the respective values of the unknown are derived from the position on the plot of the couple of responses for that depth, with respect to the closed curve. For instance, on a plot of C/(C+O) yields, the curve is a parallelogram two concurrent sides of which form a coordinate system; the coordinates of each response corresponds to the values of the unknown respectively for the formation and the borehole.

摘要： Systems, methods, and devices for inelastic gamma-ray logging are provided. In one embodiment, such a method includes emitting neutrons into a subterranean formation from a downhole tool to produce inelastic gamma-rays, detecting a portion of the inelastic gamma-rays that scatter back to the downhole tool to obtain an inelastic gamma-ray signal, and determining a property of the subterranean formation based at least in part on the inelastic gamma-ray signal. The inelastic gamma-ray signal may be substantially free of epithermal and thermal neutron capture background.

摘要： A method is provided to detect neutrons using a boron-shielded gamma-ray detector, which will detect the 0.48-MeV prompt gamma ray due to the 10B (n,α)7Li reaction. The gamma ray detector can be a proportional gas counter, a scintillation based detector, or a semiconductor detector. Monoenergetic prompt gammas will produce a sharp peak in the pulse height spectrum of a gamma-ray spectroscopy detector. By surrounding a gamma detector with a layer containing 10B, we can measure the gamma signal and neutron signal at the same time and at the same physical location in an instrument. The approach can be used to measure neutron porosity simultaneous with gamma-ray counting or spectroscopy at the same location as long as the 0.48-keV gamma-ray from the neutron reaction does not interfere with the gamma-ray measurement.
