Abstract: The method of first arrival picking of seismic refraction data is embodied in software that uses the ?-p transform on energy-ratio seismic records. First, the seismic shots are gathered. Next, the energy ratio (ER) is computed, and then the ?-p transform of the energy ratio is computed. Using a binary mask, a corresponding first arrival energy is selected. The transform is combined with the binary mask and presented as input to an inverse ?-p transform. The inverse transform data is then thresholded, and indices of ER first arrivals are detected based on the thresholds. The software then creates a vector of indices or time samples of picks. This method can be used to better guide the subsequent careful picking of first arrivals. Moreover, the method automatically interpolates missing picks.

Abstract: The ultrasound imaging tool for rock cores includes an ultrasound generator that can be inserted at selected depths into a drilled bore in a geological core sample. An array of ultrasound receivers are placed completely around the outer surface of the core sample. The ultrasound generator produces the ultrasound waves at various depths inside the bore, and the data obtained by the ultrasound receivers generates a complete 3-D ultrasound image of the core sample.

Abstract: Contamination monitoring of high voltage insulators provides a system and method producing an early predictor for high voltage insulator failure, allowing repairmen to either already be on site when a high voltage insulator fails in order to expedite repair time, or allowing repair and/or replacement of a faulty insulator before the failure actually occurs. The system and method provide transmission of an alarm signal when contaminant levels (such as equivalent salt deposit density (ESDD) levels) formed on a high voltage insulator exceed pre-selected threshold values, indicating the likelihood of high voltage insulator failure.

Abstract: Apparatus and methods are described for attenuating noise associated with atmospheric pressure fluctuations in a seismic signal during seismic data acquisition using at least a pair of sensors comprising a seismic sensor and a pressure sensor for concurrently receiving a seismic signal and a pressure signal respectively, the sensors being adapted individually to transmit the respective seismic and pressure signals to a remote recording station which is adapted to record a plurality of seismic and pressure signals; and a filter for removing, at least partly, noise associated with atmospheric pressure fluctuations in the seismic signal, the filter employing an input signal from the pressure sensor; and a model of the coupling between the atmosphere and the ground to generate a reference signal which is combined with the seismic signal to produce an output signal.
