The antenna set includes first, second and third antenna elements. The second and third elements, being structurally identical but differentially coupled, are positioned in electromagnetic symmetry about the first antenna element. Either the first antenna element or the differentially coupled second and third antenna elements may be energized by suitable circuits, while the other is coupled to circuits for receiving signals indicative of a set characteristic. In another wall-engaging apparatus for microinductively investigating a characteristic of earth formations traversed by a borehole, a transmitter antenna is mounted in a conductive wall-engaging body, within a volume bounded in part by an integral conductive backplane and conductive side wall and opening to the wall-engaging face of the body, for coupling focused electromagnetic energy into a formation. The volume preferably is conformal with the transmitter antenna. Circuits are provided for energizing the transmitter antenna and for detecting a magnetic field from the engaged formation arising from the coupled electromagnetic energy.

摘要： A method for drilling a well includes applying a current across a drill collar that surrounds an internal magnetometer. The current travels across the drill collar and along one or more other current paths to return to the drill collar. The method also includes using the magnetometer to measure magnetic fields due to the current being applied across the drill collar and the current across one or more other current paths while the drill collar is disposed at a first angle of rotation and rotating the drill collar to a second angle of rotation. The method further includes measuring the magnetic fields using the internal magnetometer while the drill collar is disposed at the second angle of rotation and determining a relationship between the current across the drill collar and a portion of the magnetic fields due to the current across the drill collar measurable by the internal magnetometer.

摘要： A three dimensional ornament is provided that is configured to be suspended from a tether and rotate to provide the appearance of different shapes as the ornament rotates. The ornament comprises a frame construction with an open interior and a frame member perimeter. An upper apex affixes to a swivel joint and is aligned with the lower apex of the ornament along the ornament centerline. The centerline of the ornament separates the left side from the right side of the ornament, whereby the frame members and corresponding connecting apexes of the frame member periphery are mirror images of one another across the centerline of the ornament. As the ornament spins, it projects a changing image from an onlooker's perspective, which changes throughout the ornament rotation and based on the rotation speed thereof.
