摘要： A method for controlling the electrical power delivered to a downhole system. The downhole system may include a power supply, a downhole tool, and a wire or cable connecting the downhole tool to the power supply. A resistive load, such as a motor, is included with the downhole tool. The power supplied to the downhole tool is dynamically adjustable to match the resistive load voltage and power rating. Dynamically adjusting power is accomplished by varying voltage from the power supply, varying the resistive load requirements, or a combination of both.

摘要： This disclosure describes a dielectric logging tool for evaluating the earth formation using at least one transmitter antenna disposed in a cavity on a pad engaged with a borehole wall. The logging tool may comprise at least one power driver in electrical communication with the at least one transmitter antenna and configured to modulate a phase of output current of the at least one power driver. The logging tool may enforce symmetric current on both feeds of the at least one transmitter antenna causing a point of symmetry of the current to align with an axis of geometric symmetry of the at least one transmitter antenna. A parameter of interest of the formation may be estimated by using the attenuation and phase difference between the received and transmitted signals or between received signals from spaced receivers.

摘要： An apparatus for use in a borehole may include a rotor having at least one set of magnetic elements and a cylindrical stator having a winding flowing current in a direction transverse to a long axis of the stator. The polarity of each magnetic element of the rotor may be arranged to alternate along a long axis of the rotor. The stator may be in sliding engagement with the rotor and have a core formed at least partially of laminations aligned along a plane co-planar with the long axis of the stator. Energizing the winding principally causes relative sliding between the rotor and the stator. A method for performing an operation in a borehole includes forming a well tool having at least one linear motor as described above, conveying the linear motor into the borehole, and operating a well tool by activating the linear motor.

摘要： Time lapse seismic measurements of a laminated reservoir (401) including sands and shale are processed to determine changes in the laminated reservoir (403). An initial petrophysical model is obtained at a well bore from measurements made with a multi-component resistivity-logging tool (405). Changes in the amplitude versus offset behavior of the reflections from the top of the reservoir are indicative of changes in fluid saturation and/or formation pressure.

摘要： Measurements made by a cross-dipole acoustic logging tool in a borehole are processed to determine the principal directions of azimuthal anisotropy of a subsurface formation. Measurements such as in data tracks (601, 603) are also made for correlation and comparison purposes of a Gamma Ray Log (621), a Caliper Log (623), a Density Log (631) and a Neutron Porosity Log (633). Measurements indicative of azimuthal resistivity logging variations and conductivity logging variations (605, 607, 609, 611) are also made with a multicomponent induction logging tool that is capable of performing electrical measurements at a number of different frequencies that also covers a range of different downhole depths. These electrical measurements are processed using the principal direction determined from acoustic measurements to give an estimate of azimuthal resistivity variations. Based on modeling results, azimuthal resistivity variations are interpreted to estimate a fracture depth in the rock for known fluids therein.
