摘要： A method of processing magnetic field measurements to obtain magnetic dipole density image data is provided. The process involves making measurements of total magnetic field at a plurality of locations over an area of interest, dividing the area of interest into a plurality of narrow parallel strips, performing a strip integral and forming and solving a system of linear equations to obtain a generalised projection. The process is then repeated to produce a plurality of generalised projections from the original measured data by performing strip integrals for a plurality of different orientations of the strips. The process is then completed by performing an inverse Radon transformation on the generalised projections to obtain the magnetic dipole moment density image data.

摘要： A digital induction resistivity logging tool is disclosed for digitally measuring both the in-phase (R) and quadrature (X) phase components in a receiver signal generated in response to transmitter induced currents flowing in the earth's subsurface formations. The digital induction tool includes a digital sinewave generator for generating a highly phase stable, low distortion transmitter signal, the frequency of which is selectable from among a plurality of transmitter frequencies. One phase sensitive detector is used alternately to detect both the R and the X phase component signals. Automatic phase compensation is included to periodically compensate for both static and dynamic temperature dependent phase shift errors due to circuits of the tool involved in the component measurements. A floating point analog-to-digital converter capable of handling the wide dynamic range in the detected phase component signals is provided to convert the phase detector output into digital signals. Selection of the transmitter frequency may be based on optimizing the measurement of the characteristic of the formations being encountered by the tool. A linearization correction function is obtained periodically for the tool transfer function as the tool is being used in normal logging operations. The function is then applied to measurements taken subsequently.

摘要： Each of the N surface images, used to restore the borehole or the core sample surface image, is segmented into related components (C (12), C (11),...) which are grouped into related regions (C (8)), each touching both the right and left edges of the image. After smoothing out their contours, the related regions are represented in the form of an image, called bed image, representative of the stratification beds. The contours appearing on the N bed images are matched to construct the bed boundary sinusoïdal curves. The invention is particularly useful in determining stratification of a geological site.

摘要： An improved system and method for performing inversion and for correcting for shoulder bed effect. The method enhances the resolution of wave propagation resistivity logs and corrects the logs for adjacent bed effects, whereby the resulting logs have a vertical response as good as wireline high-resolution induction logs. The method first performs logging while drilling on a formation to obtain LWD resistivity log data. The method then selects one or more control depths at one or more locations of each of a plurality of detected beds in the formation. The present invention includes a novel method for selecting bed boundaries from the log data, and the control depths are then determined based on the determined bed boundaries. The method then estimates the resistivity of each bed only at the selected control depths to produce an estimated resistivity of the beds. The method then computes a simulated log value at each control depth using a current estimate of the resistivity of the beds. The computed simulated log is then compared to the actual log data at each control depth, and the resistivity of each bed is adjusted using the difference between the actual and simulated values at the control depths. The above method iteratively repeats a plurality of times until the simulated log substantially matches the actual log at the control depths. The method for determining the bed boundaries in the formation preferably comprises fitting a cubic polynomial in depth to the conductivity, or log of the conductivity, using a weighted linear least-squares method. The curve fit of the log data is performed a plurality of times on portions of the log data using a windowing method. This windowing method comprises moving a window across the log data at periodic increments, and performing the curve fit on the window of log data at the periodic increments as the window is moved across the log data. The method then determines inflection points of the log data after the curve fit for each of the windows. The method then selects bed boundaries from the inflection points of the curve-fit of the log data.

摘要： A method of determining a parameter of a physical model representing the electrical behaviour of a composition is provided. The method comprises defining said model by a relationship between at least one electrical property of the composition, a plurality of physical variables of the composition and said parameter, and measuring a first electrical property of the composition. A sample which is representative for said composition is selected, and a second electrical property of the sample is measured for various magnitudes of at least one of said physical variables. An incoherence function is selected, defining a difference between the measured electrical properties and the electrical properties as calculated from said relationship, said incoherence function being such that independent measurements are weighted in dependence of their accuracy. Said parameter is determined by minimisation of the incoherence function. The first and second property can be the same property.
