摘要： A method for estimating a permeability of a formation surrouning a borehole comprises applying transient well-test conditions to the borehole. A portion of the formation is excited with an acoustic signal. The acoustic response corresponding to the acoustic exciting is measured with an acoustic receiver located within the borehole. The permeability of the formation is estimated using the acoustic response.

摘要： A method for determining for a reservoir (1) containing fluids (W, O), the variation in the relative permeability (krO, krW) of at least one of the fluids, as a function of the saturation of at least one of the fluids (W, O),) is provided. According to this method a saturation distribution of one of the fluids of the reservoir is determined on the basis of a measurement of a physical property in the reservoir. A dynamic model (20) for the flow of fluids in the reservoir (1) is created. The dynamic model generates a saturation distribution. The saturation distribution (40) generated by the dynamic model is compared with saturation distribution obtained from measurement. The dynamic model (20) is updated with intermediate relative permeability values (krO)i and (krW)i and steps b and c are repeated if the saturation distribution generated by the dynamic model and that determined on the basis of measurement do not coincide.

摘要： A method for depth matching borehole images and/or core section images is disclosed wherein signals from sensors at different levels on a logging tool are converted into an averaged signal representing the average bed signal at the center of the borehole at each of the different levels. A depth matching technique is applied to the averaged signals from the sensors at different levels on the logging tool to determine the optimum depth offset necessary for matching two sets of signals from sensors at the different levels of the logging tool. In an alternative embodiment of the invention a Hough transform is utilized to process the well log images and generate three-dimensional images in Hough space. The three dimensional images are converted into two-dimensional extremum curves. Depth matching is performed on the two dimensional extremum curves to calculate an offset to match the two dimensional extremum curves. The calculated offset is then applied to the well log images to depth match them.

摘要： A method of characterizing texture heterogeneities in a geological formation traversed by a borehole. The method records an image of the borehole wall such as that provided by Schlumberger's Formation Microscanner (FMS) apparatus, representative of variations in a physical parameter of the formation in the longitudinal direction of the borehole and around the periphery of the wall. Geological objects are extracted from the image corresponding to a determined morphological type of heterogeneity. The variation in at least one attribute defined for this type of heterogeneity in the longitudinal direction of the borehole is determined. The invention is particularly applicable to vug detection.

摘要： Data representing a two-dimensional image of the resistivity of a sector of a borehole wall is processed to produce selected flow-line data delineating the boundaries of beds of subsurface earth formations along sectors of the borehole. The latter bed-delineating image data for several circumferentially-spaced sectors is further processed to derive and present data defining the orientations of dip planes, by matching the bed-delineating flow-lines for the several sectors. This is done by focusing the latter flow-lines on a root flow-line, correlating those flow-lines to the root flow-line, and linking the flow-lines to the root flow-line according to a path of minimum cumulative cost.

摘要： A morphological survey of geological formations traversed by a borehole includes constructing, from an initial image of the wall of the borehole representative of variations in a physical parameter of the formation in the longitudinal direction of the borehole (“depth”), and in the peripheral direction of the borehole wall (laterally), a “crossing-component image.” The cross-component image includes only those components of the parameter that extend all the way across the initial image from one side of the image to the other. The survey includes determining variations in one or more attributes relating to the parameter in the crossing-component image as a function of depth. The variations providing information relating to morphology to indicate solid zones, bedded zones, or different types of heterogeneous zones, for example.
