摘要： An apparatus includes a sub with recesses along an exterior wall to receive inserts, an antennae case including a coil surrounded by a sacrificial wear portion of a material through which signals between the coil and a formation of interest may pass. An eroded outer wall of the sacrificial wear portion is restorable by application of an uncured restorative material to the antennae case. A method includes securing an antennae case having a coil there within onto a sub, surrounding the coil with a metal sleeve shield, and radially receiving and securing a multi-piece sacrificial wear member intermediate the antennae case and a retainer ring having a threaded bore. The multi-piece sacrificial wear member is replaceable after use by unthreading the retainer ring to release the sacrificial wear member for radial removal from the sub.

摘要： A method, including generating a magnetic field in a region from a first magnetic field radiator located at a first position and a second magnetic field radiator located at a second position. A volume having a multiplicity of vertices is delineated within the region, and respective values of the magnetic field at the multiplicity of vertices are measured. In response to the respective values, respective first dipole moments to the first magnetic field radiator and respective second dipole moments to the second magnetic field radiator are assigned. A value of the magnetic field within the volume is calculated in terms of the first dipole moments and the second dipole moments.

摘要： A fixture for receiving a tool that facilitates communication between a tool and other equipment. The fixture includes a shroud sized to at least partially cover a circumference of a housing of the tool, and one or more current transformers or sensors which are coupled to the shroud. Each current transformer can inductively receive or inject, through the housing, a current from or into electronics contained within the housing of the tool. The induced current can be part of the communication between the tool and the equipment. The communication can be a data communication between the tool and the equipment, a transfer of electrical power from the equipment to the tool, or both. The tool can be a closed cavity without electrical or magnetic interfaces.

摘要： A system method and computer-readable medium for correcting measurements obtained by a down hole tool for residual measurement errors is disclosed. A down hole tool having at least two directional field sensors is disposed in a borehole. The at least two directional sensors are substantially orthogonal to each other and to a longitudinal axis of the down hole tool. Measurements are obtained from the at least two directional sensors during rotation of the tool by at least 360 degrees around the longitudinal axis of the tool. Residual measurement errors are determined for the obtained measurements, and a quality level of the determined residual measurement errors selected. The determined residual measurement errors are applied to the obtained measurements when the determined residual measurement errors are consistent with the selected quality level. In various embodiments, the residual measurement errors are reduced from a first value that does not match the selected quality level to a second value that are consistent with the selected quality level.

摘要： The invention relates to a device for monitoring the reliability of the detection unit of an apparatus for detecting metal pollutants (I) in materials passing through same, including a metal gauge (1) and a means (2) for transporting said gauge in the detection device. The transport means of the device is arranged to prevent any contact between said gauge and materials passing through the detection device. Accordingly, there is no contamination between the gauge, the materials and the environment, and there is no risk of losing the gauge among the materials.

摘要： Techniques are disclosed relating to marine geophysical prospecting. According to some embodiments, a survey vessel may tow (152) a streamer through a body of water. If the streamer needs to be maintained (e.g., cleaned, repaired, or serviced), a second vessel may lift the streamer out of the water for this purpose (154). Techniques are disclosed that are relevant to the handling of protruding members (such as streamer steering devices) on the streamer.
