摘要： A method and a resistivity image logging tool connected or connectable to one or more processing devices process geological log data to construct missing information from destroyed or occluded parts using cues from observed data. The geological log data signals can be generated through use of the logging tool having one or more electrodes interacting with a formation intersected by a borehole. The processing involves the steps of: in respect of one or more data dimensions associated with missing values in a log data set, decomposing the signal into a plurality of morphological components; and morphologically reconstructing the signal such that missing values are estimated.

摘要： A method for determining geological subsurface resistivity. The method includes obtaining a set of lightning parameters associated with a lighting strike received by a geological volume of material, the set of lightning parameters including an indicium of the current of the lightning strike at a first initial time and an indicium of the current of the lightning strike at a first decay time subsequent to the first initial time, and inferring the resistance of the volume of geological material, at least in part, from the set of lightning parameters.

摘要： In a method for operating a magnetic resonance imaging system to generate a magnetic resonance data file, raw magnetic resonance data are acquired, and k-space is established in a computerized storage medium, with k-space being divided into a contiguous central region and a contiguous region surrounding the central region. In a computerized procedure, the raw data are entered into k-space at a constant sampling rate for both of the central and peripheral regions, while sampling the central region with a first density of sampling points, and sampling the peripheral region at a second density of sampling points that is less than the first sampling density. The set of data points thereby representing sampled k-space is made available in a data file as an output from the computerized procedure, in a form allowing an image to be reconstructed from the contents of the data file.

摘要： The use of Electrical Impedance Tomography (EIT) to map subsurface hydraulic conductivity. EIT can be used to map hydraulic conductivity in the subsurface where measurements of both amplitude and phase are made. Hydraulic conductivity depends on at least two parameters: porosity and a length scale parameter. Electrical Resistance Tomography (ERT) measures and maps electrical conductivity (which can be related to porosity) in three dimensions. By introducing phase measurements along with amplitude, the desired additional measurement of a pertinent length scale can be achieved. Hydraulic conductivity controls the ability to flush unwanted fluid contaminants from the surface. Thus inexpensive maps of hydraulic conductivity would improve planning strategies for subsequent remediation efforts. Fluid permeability is also of importance for oil field exploitation and thus detailed knowledge of fluid permeability distribution in three-dimension (3-D) would be a great boon to petroleum reservoir analysts.
摘要翻译： 使用电阻抗层析成像（EIT）来绘制地下水力传导性。 EIT可用于绘制在地下测量幅度和相位的水力传导率。 液压传导性取决于至少两个参数：孔隙度和长度尺度参数。 电阻层析成像（ERT）测量并映射三维导电性（可与孔隙度相关）。 通过引入相位测量以及幅度，可以实现相关长度尺度的期望的附加测量。 液压导电性控制从表面冲洗不需要的流体污染物的能力。 因此，廉价的水力传导图可以改进后续修复工作的规划策略。 流体渗透性对于油田开采也是非常重要的，因此三维（3-D）流体渗透率分布的详细知识将对石油储层分析师是一个很大的好处。

摘要： A spectrogram of secondary magnetic field strength as a function of frequency and spatial relationship is used to identify hidden objects. A time-varying multi-frequency primary electromagnetic field is generated, preferably over the range 100 Hz to 300 kHz, which induces a time-varying multi-frequency secondary electromagnetic field about the hidden object. The strength of the secondary field, typically inphase and quadrature, is plotted as a spectrogram over a low frequency broadband spectrum as a function of frequency and spatial relationship between the hidden object and the secondary field strength detector. From this spectrogram, indications may be had of the hidden object's characteristics such as location, size and shape, and material composition. Preferably, the measured spectrogram is compared against a library of reference spectrograms by a computer to identify the hidden object.

摘要： A magnetic susceptibility log is run through an earth formation to identify the presence of any select non-magnetic minerals in association with magnetic minerals. The select non-magnetic mineral is identified as being present when the magnetic susceptibility measurement exceeds a level at which a measurable concentration of the select non-magnetic mineral is expected to be present.

摘要： A computer-implemented method includes: receipt and accession of magnetic field data from a constellation of satellites providing global coverage over the Earth in a time span less than one day; inter-calibrating the magnetic field data from all satellites to a common standard; quantifying the global magnetic disturbance and selecting quiescent intervals at least as short as one day for evaluation of Earth's internally-generated field; calculating global maps of the mean vector magnetic field for each quiet interval from the average of all satellite measurements in angular bins; converting the time sequence of global maps of the mean fields to time series of angular harmonic coefficients via direct convolution; applying spectral and regression analysis to the harmonic coefficient time series to identify and remove artifacts in the signals; reconstructing a continuous time and spatial representation of the magnetic field continuous in time and angular position globally.
