  • Patent number: 10422880
    Abstract: Doppler correction of phase-encoded LIDAR includes a code indicating a sequence of phases for a phase-encoded signal, and determining a first Fourier transform of the signal. A laser optical signal is used as a reference and modulated based on the code to produce a transmitted phase-encoded optical signal. A returned optical signal is received in response. The returned optical signal is mixed with the reference. The mixed optical signals are detected to produce an electrical signal. A cross spectrum is determined between in-phase and quadrature components of the electrical signal. A Doppler shift is based on a peak in the cross spectrum. A device is operated based on the Doppler shift. Sometimes a second Fourier transform of the electrical signal and the Doppler frequency shift produce a corrected Fourier transform and then a cross correlation. A range is determined based on a peak in the cross correlation.

  • Patent number: 10422895
    Abstract: Passive components adapted for integration with at least one active semiconductor device, in an embodiment, comprise at least one metallic structure dimensioned and arranged to absorb and/or reflect a major fraction of incident electromagnetic radiation received at one or more wavelengths of a first group of wavelengths. This prevents radiation within the first group of wavelengths from being received and/or processed by the at least one active device. In an embodiment, one or more metallic structures are dimensioned and arranged to direct an amount of incident radiation, received at one or more wavelengths of a second group of wavelengths, sufficient to enable receiving or processing of incident radiation within the second group of wavelengths by the at least one active semiconductor device. In some embodiments, the passive component comprises a passive optical filter for use in spectroscopic applications, and the active semiconductor device is a detector or sensor.

  • Patent number: 10422897
    Abstract: Described herein is method for the detection of seismic activity using a network of lights, and in particular, street lights (43) arranged over a number of streets (42). Each light includes a control module having the facility for both long- and short-distance communication, the control modules being grouped with other control modules and associated with a group controller to create a short-distance or mesh network. Each control module includes a sensor which is capable of detecting seismic activity and data relating to such activity may be transmitted to a central server via its group controller using long-distance communication. Even if the sensors are relatively inaccurate, the high number of such sensors present in the network makes it possible to detect and analyze the activity using geocoordinate information provided by the control modules at the server.

  • Patent number: 10422899
    Abstract: A deterministic method for selecting a set of encoding weights for simultaneous encoded-source inversion of seismic data that will cause the iterative inversion to converge faster than randomly chosen weights. The encoded individual source gathers are summed (83), forming a composite gather, and simulated in a single simulation operation. The invention creates multiple realizations of the simulation (84), each with its own encoding vector (82) whose components are the weights for the shots in the composite gather. The encoding vectors of the invention are required to be orthogonal (82), which condition cannot be satisfied by random weights, and in various embodiments of the invention are related to eigenvectors of a Laplacian matrix, sine or cosine functions, or Chebyshev nodes as given by the roots of Chebyshev polynomials. For non-fixed receiver geometry, an encoded mask (61) may be used to approximately account for non-listening receivers.

  • Patent number: 10422902
    Abstract: A method is herein presented to statistically combine multiple seismic attributes for generating a map of the spatial density of fractures. According to an embodiment a first step involves interpreting the formation of interest in 3D seismic volume first to create its time structure map. The second step is creating depth structure of the formation of interest from its time structure map. In this application geostatistical methods have been used for depth conversional, although other methods could be used instead. The third step is extraction of a number of attributes, such as phase, frequency and amplitudes, from the time structure map. The next step is to project the fracture density onto the top of the target formation. The final step is to combine these attributes using a statistical method known as Multi-variant non-linear regression to predict fracture density.

  • Patent number: 10422904
    Abstract: A measure of structural growth of subsurface geological formations layers or intervals is obtained to investigate and analyze layer structure development history. The measure or indication can be considered a structural growth index (SGI) and is used to evaluate for possible presence of hydrocarbons in the layers or strata in a structure of concern. The structural growth measure or index for a given geologic interval of interest is defined as the ratio of the layer thickness difference measured at two selected locations, one at a structural high and the other at a structural low of layer or interval, over the larger number of the paired-thickness measurements. The structural growth measure is determined for a series of sequentially layered geologic formations of interest and displays of determined measures are formed as functions of geologic time for the formations. Based on the structural growth measure, the geologic growth history of the given oil field structure is revealed quantitatively.

  • Patent number: 10422907
    Abstract: A method for seismic geological lineation mapping, wherein a seismic dataset is collected, with information about minor lineations generated by subtle structural geological features in an underground earth formation. Seismic attribute volumes are identified in the seismic dataset, relating to trace continuity, amplitude, frequency and phase. The attribute volumes may have an insufficient resolution to display the minor lineations. A seismic multivolume lithological lineation map is generated, in which single attribute lineation maps generated for each of the identified seismic attribute volumes are combined to accurately display the minor lineations generated by the subtle geological features.
