Abstract: An oscillatory apparatus and methods of utilizing the same. In one embodiment, the apparatus comprises a force sensor having a proof mass, with one or more sensing electron tunneling electrodes disposed thereon, and a frame comprising one or more reference electron tunneling electrodes. Conductive plates disposed on the sensor base and capping wafers induce oscillations of the proof mass. The sensing and the reference electrode pairs are disposed in a face-to-face configuration, thus forming a digital switch characterized by one or more closed states. In the closed state, the switch generates triggering events, thereby enabling the sensing apparatus to generate a digital output indicative of the mass position. The time period between consecutive trigger events is used to obtain mass deflection due to external forcing. Time separation between the triggering events is based on the physical dimensions established during fabrication, thus not requiring ongoing sensor calibration.

The transmitter also senses pressure and temperature conditions at its borehole location to provide indications of detected potential problems in the well from the survey or other sources, and to reduce risks and enhance safety and quality of the operations.

Abstract: Systems, methods, and software for detecting boundary locations of multiple subsurface layers are described. In some aspects, the boundaries of multiple subsurface layers in a subterranean region are identified based on measurements associated with multiple different transmitter-receiver spacings. The measurements are generated based on operating multiple transmitters and multiple receivers of a resistivity logging tool at a tool depth in a wellbore in the subterranean region. A first pair of the subsurface boundary locations are determined based on a first measurement associated with a first transmitter-receiver spacing. A second, different pair of the subsurface boundary locations are determined based on a second measurement associated with a second, longer transmitter-receiver spacing. The first pair of subsurface boundary locations reside between the second pair of subsurface boundary locations in the subterranean region.

Abstract: A first off resonance radio frequency (RF) pulse and a second off resonance RF pulse having a phase difference of 180 degrees from the first off resonance RF pulse are applied, one or more auxiliary gradient magnetic fields for offsetting inhomogeneity of a main magnetic field generated by applying the first and second off resonance RF pulses are applied, and magnitudes and signs of the auxiliary gradient magnetic fields are appropriately adjusted. Therefore, artifacts generated due to inhomogeneity of a main magnetic field in an imaging method using an off resonance RF pulse may be removed. When this method is applied to an imaging method using a spatial pre-saturation RF pulse, the phenomenon in which spins excited by the pre-saturation RF pulse are excited again by the off resonance RF pulse to return signals, such that undesired signals overlap and appear in an ultimately-obtained signal, may be removed.
