20210011184 | SEISMOMETER - The seismometer uses the interference between light emerging from two closely spaced slits to create an interference pattern. A light detector is used to detect the amplitude of the interference pattern at a specific spatial position. One slit is part of a support for the seismometer, and the other slit is on a pendulum suspended from the support. Vibrations from an earthquake are communicated much better to the slit which is part of the support as compared to the slit on the pendulum. Thus, the vibrations result in a relative movement between the slits and this change in separation between the slits results in the interference pattern from the slits to move. The change in the interference pattern changes the amplitude at the light detector, thereby providing a detectable measurement of vibrations. | 2021-01-14 |
20210011185 | FIBER OPTIC NOISE MITIGATION FOR DISTRIBUTED ACOUSTIC SENSING - To mitigate zigzag noise and increase the quality of data provided from DAS VSP in wells with significant vertical sections, zigzag noise characteristics are identified and quantified. The zigzag noise properties can be extracted from an analysis of an autocorrelation of DAS VSP traces. The zigzag noise has a characteristic time period or repeat time delay that is the time period for the noise to propagate along the wireline through a zone of the wellbore with poor acoustic coupling between the fiber optic cable and formation. This period can be identified from analysis of the autocorrelation referred to herein as a crosswise lag summation function. The crosswise lag summation function identifies groups of DAS data traces containing zigzag noise and outputs zigzag noise periodicity for each group of traces. Once it has been identified, the zigzag noise can be removed from the VSP data and improve formation evaluation. | 2021-01-14 |
20210011186 | ONSHORE SEPARATED WAVE-FIELD IMAGING - A method for applying separated wave-field imaging onshore (1) by artificially creating up-going and down-going fields and (2) by using these fields in a migration algorithm.

The signals emitted from each jaw are antiphase to one another, such that they are additive to a utility wire disposed between the jaws but out of phase with respect to any utility not between the jaws. The signal is thus induced on the utility wire and can be detected as emitted from its below ground length by a conventional locator. | 2021-01-14 |
