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： The present invention provides a new method to determine corrected characteristics of materials using the measured quantities obtained by a measurement and an extensive set of database points representing laboratory and modeled results in well defined environments. In particular the invention relates to the measurement of the characteristics of the formation around a wellbore as well as of the borehole with a well logging tool. Using a dynamic parametrization technique, the environmental corrections and the transformations from the measured to the physical characteristics can be achieved in a more accurate, robust and flexible way. The dynamic local parametrization is based on a weighted multiple linear regression over the entire database to obtain the local coefficients for the transformation which can be expressed as a simple equation.

摘要： A method for tool path identification in formation evaluation includes obtaining measurements of formation properties in azimuthal sectors for each of a plurality of depth levels; calculating quality factors from the measurements; identifying a centroid or maximum of the quality factors among the measurements in each of the azimuthal sectors for each depth level; and associating the centroid or maximum of the quality factors at each depth level along a borehole to form the tool path. Calculating the quality factors may include parameterizing the measurements according to at least one factor selected from a spine factor, a rib factor, and a volumetric photoelectric factor. A method for determining corrected measurements for formation properties includes identifying a tool path from measurements taken in azimuthal sectors at each depth level along a borehole; and calculating a corrected measurement at the each depth level by averaging measurements in the azimuthal sectors adjacent the tool path.

摘要： A method for determining at least one formation property calculated from neutron measurements acquired with a downhole tool includes emitting neutrons from a source in the tool into the formation, detecting neutrons with at least one detector in the downhole tool, calculating a first slowing-down length (L1) based on the detected neutrons, and deriving a second slowing-down length (L2) based on the first slowing-down length (L1). Further steps include deriving a correlation function for relating slowing-down lengths from a first tool to slowing-down lengths associated with a different source, wherein the correlation function depends on formation properties such as bulk density; and applying the correlation function to the slowing-down length of the first tool to derive the slowing-down length of the second tool. A method for determining a thermal neutron formation porosity based on a slowing-down length from epithermal neutron measurements from an electronic neutron source includes converting the slowing-down length into a computed neutron slowing-down length from thermal neutron measurements from a chemical neutron source, wherein the converting uses a correlation function that depends on formation bulk density; deriving a thermal neutron countrate ratio based on the computed neutron slowing-down length, wherein the deriving uses a function that depends on the formation bulk density and formation sigma; and computing the thermal neutron formation porosity from the thermal neutron countrate ratio.
