Abstract: Methods and related systems are described for analyzing electromagnetic survey data. Electromagnetic survey data of a subterranean formation is obtained using at least a downhole transceiver deployed in a borehole and a transceiver positioned on the surface, or in the same or another borehole. Limits are defined for casing correction coefficients that account for effects of the borehole casing. A constrained inversion process is performed solving for the casing correction coefficients within the defined limits, and for one or more parameters of a model representing attributes, such as resistivity, of the subterranean formation.

Abstract: A signal processing circuit for a rotation detector includes a normal-rotation pulse request holding portion, a reverse-rotation pulse request holding portion, a resetting portion, and a waiting time switching portion. When an output of one of a normal-rotation pulse and a reverse-rotation pulse is finished and a waiting time elapses, the resetting portion resets an output request signal of the one of the normal-rotation pulse and the reverse-rotation pulse held by one of the pulse request holding portions. The waiting time switching portion sets the waiting time to a first waiting time when one of the pulse request holding portions holds the output request signal, and the waiting time switching portion sets the waiting time to a second waiting time longer than the first waiting time when both the pulse request holding portions hold the output request signals.

Abstract: A waveform design method is presented for controlled source electromagnetic surveying. A desired source spectrum (82) is specified based on a desired resistivity depth image resolution (81) with spectral amplitudes determined by expected noise levels (83). Techniques are disclosed for designing a source waveform to match the desired source spectrum. When better resolution is desired at a target zone, this leads to a required clustering of frequency components. A modulated waveform can be used to provide this clustering of frequency components.

Abstract: A method for determining a failure of a membrane in a fuel cell in a fuel cell stack. The method includes measuring the voltage of each fuel cell in the fuel cell stack, calculating an average cell voltage from all of the cell voltages of the fuel cells in the fuel cell stack, and identifying a minimum cell voltage from all of the cell voltages of the fuel cells in the fuel cell stack.

Abstract: The disclosure relates to a method for measuring a flow rate, in particular in an inductive flowmeter, in which an electrical signal is applied to a measuring medium flowing in a measuring tube at electrodes, and the response function at measuring electrodes is determined as a measure of the flow rate, and to a corresponding flowmeter device. So that the flow effects of gas bubbles and/or particles in the measuring medium can be distinguished from other faults and the determination of the flow rate is thus more reliable, the disclosure proposes that, in order to detect gas bubbles and/or particles in the measuring medium, a magnetic and/or electric field is applied to the latter and the potential and/or current is/are read out at one or more electrodes, the signal profile A(t), together with its signal-to-noise component, is measured electronically as a function of the time, and a statistical evaluation is used to infer the existence of gas bubbles and/or particles.
