Abstract: The response characteristics of a combination of hole-centered electric logging tools in a variety of borehole conditions can be obtained by means of impedance values as entries of a matrix resulting from measurements over a series of depth increments, utilizing an array of 2M-1 electrode assemblies of equal incremental spacing positioned on a rigid mandrel. While the array moves continuously along the borehole, current is continuously emitted from the centrally located current electrode allowing the impedance matrix to be formed by the principle of linear superposition in terms of voltage and voltage difference measurements between adjacent electrodes. The impedance matrix is inverted and used to generate a set of tool responses, which when properly compared to a set of tool responses previously generated by computer simulation and addressable by sets of borehole parameters and calibration factors, allows the corresponding borehole conditions to be deduced from the measured data.

Abstract: The present invention relates to an electric valve device used in remotely operable applications. It comprises a valve body with a centrally placed slidable valve core. The core has an aperture for fluid passage and may be held in position by an electromagnet in the valve body. Windings are placed in one end of the valve body so that they encircle the slidable core and a spring is placed in the other end. To move the core, a DC current source is connected to the windings so that when they are energized a force is generated to move the core in a specific direction. The core is then held in this position by the contact between the electromagnet in the valve body and the valve core until the current in the magnetic windings is switched off, then the spring return to the core to its original, closed position.
