Abstract: Wireless communication and electromagnetic telemetry between various surface or downhole devices may be provided using two or more dipole antennas. The dipole antennas may be formed, for example, by electrically isolating, for each electric dipole antenna, two electrically conductive portions. The two electrically conductive portions are part of a downhole casing, a downhole liner, a completion, a production tube, or a downhole tool. The two or more electric dipole antennas are disposed in different sections of a completed well, in one or more lateral wells, in different completed wells, or in any combination of those. An electromagnetic signal is transmitting from at least one of the two or more dipole antennas and received at any other of the two or more dipole antennas, thereby providing telemetry or wireless communication between the dipole antennas of the petrophysical devices.

Abstract: Devices and methods for obtaining borehole images at a surface installation while a borehole-imaging downhole tool is logging a borehole are provided. One such method may involve, while the downhole tool is disposed in the borehole, obtaining a first borehole image at a first depth of investigation using the borehole-imaging downhole tool. Compression electronics may compress the first borehole image to obtain a first compressed borehole image. Compressing the first borehole image may involve exploiting a symmetry characteristic of the first borehole image to increase compression efficiency or exploiting a similarity of the first borehole image with a second borehole image to increase compression efficiency, or both. The compressed borehole image then may be efficiently transmitted to the surface installation via a telemetry system.

Abstract: Sensor array noise reduction is provided. Techniques involve systems and methods for reducing sensor array noise by estimating an instantaneous frequency of a coherent noise signal in a logging system. The instantaneous frequency may be estimated based on a rotation of an electric motor in the logging system, or may estimated by applying suitable signal processing algorithms on measurements in the logging system. A virtual measurement may be computed using the instantaneous frequency. The virtual measurement may be demodulated to obtain a baseband signal, and noise may be removed from the baseband signal to obtain a denoised signal.
