    摘要： A tool (10) for expanding a tubular member in a well, comprises: a locating device for locating the tool in the tubular member to be expanded; and an expanding device for expanding the tubular member beyond its starting diameter, the expanding device comprising a radial array of expanding elements (40), each element, in use, acting on the tubular member to deform it radially outwardly; wherein each element is moveable in an axial direction independently of the other elements in the array. A method of expanding a tubular member in a well, comprises: positioning an expansion tool in the tubular member in the well, the expansion tool comprising a radial array of expanding elements; and moving the elements in an axial direction to act on the tubular and deform it in a radial direction, each at least on element moving in an axial direction independently of others in the array. A system comprises a tool suspended on a wireline cable and connected to control equipment located at the surface so as to be operable in a well to expand tubular members located therein.

    摘要： Methods for downhole waveform tracking and sonic labeling employ "tracking algorithms" and Bayesian analysis to classify STC waveforms. More particularly, according to the tracking part of the invention, a probability model is built to distinguish true "arrivals" (e.g. compressional, shear, etc.) from "false alarms (e.g. noise) before the arrivals are classified. The probability model maps the "continuity" of tracks (slowness/time over depth) and is used to determine whether sequences of measurements are sufficiently "continuous" to be classified as tracks. The probability model is used to evaluate the likelihood of the data in various possible classifications (hypotheses). Prior and posterior probabalities are constructed for each track using the tracking algorithm. The posterior probabilities are computed sequentially and recursively, updating the probabilities after each measurement frame at depth k is acquired. The classification part of the invention determines the hypotheses with the maximum "posterior probability" according to Bayes' Theorem.

    摘要： A borehole tool, comprises: a tool body; a series of arms connected to the tool body and moveable radially relative thereto; and a series of pads mounted on the arms so as to be pivotable about a radial axis relative to the tool body. By allowing pivoting of the pads about a radial axis, elongate pads can be arranged to provide different circumferential coverage according to the orientation with respect to the longitudinal axis of the borehole.

    摘要： The invention concerns a method for calculating the relative volumetric flow-rates of at least one of the phases of a multiphase effluent flowing in a well, said method comprising a first step of acquiring local volumetric fractions and/or velocities of said phases across a section of the well at a certain depth. The method further comprises: - corrections of said local volumetric fraction and/or velocity measurements in order to make them consistent with each other and/or with the effluent flow conditions; - selection of a suitable flow model mathematically representing the effluent flow; - interpolation of said local volumetric fraction measurements and/or said local velocity measurements by the selected flow model in order to obtain a volumetric fraction profile and/or a velocity profile for at least one phase of the effluent across said section of the well at said depth.- calculation of the relative volumetric flow-rates of said at least one phase by integration of said volumetric fraction and/or velocity profiles over said section of the well at said depth.
