  • Patent number: 11313988
    Abstract: A system for seismic imaging of a subterranean geological formation uses a two-way imaging condition. A seismic signal is emitted into a subterranean formation and recorded at receiver(s). Source and receiver wavefields are decomposed into respective right-down/left-up and left-down/right-up propagating waves. The right-down/left-up and left-down/right-up direction can be defined along the direction emitted from the source or receiver to corresponding direction in two dimensional (2D) case. An imaging condition for generating both a positive-dip structure image and a negative-dip structure image is the inner product of the wavefields. Applying the sample-by-sample multiplication imaging condition to the opposite dip images, the diffraction energy is retained while the reflection energy is significantly attenuated. The diffraction image can be used to detect faults and fractures in subsurface regions.

  • Patent number: 10535168
    Abstract: A method for generating an image of a subterranean formation includes receiving seismic data that was collected from seismic waves that propagated in the subterranean formation. Partition images are generated using the seismic data. A geological model of the subterranean formation is generated. Dip fields in the partition images are determined. A target dip field in the geological model is determined. A degree of correlation between the respective dip fields and the target dip field is determined. Weights are assigned to the partition images based upon the degrees of correlation to produce weighted partition images. The image of the subterranean formation is generated by stacking the weighted partition images.

  • Patent number: 10394821
    Abstract: In an embodiment, a method comprises dividing collected data into data clusters based on proximity of the data and adjusting the clusters based on density of data in individual clusters. Based on first data points in a first cluster, a first average point in the first cluster is determined. Based on second data points in a second cluster, a second average point in the second cluster is determined. Aggregate data, comprising the first average point and the second average point, are stored in storage. Upon receiving a request to provide data for a particular coordinate, the reconstructed data point is determined by interpolating between the first average point and the second average point at the particular coordinate. Accordingly, aggregated data may be stored and when a request specifies data that was not actually stored, a reconstructed data point with an approximated data value may be provided as a substitute.

  • Patent number: 10339709
    Abstract: A system and method may model physical geological structures. Seismic and geologic data may be accepted. A three-dimensional (3D) transformation may be generated between a 3D present day model having points representing present locations of the physical geological structures and a 3D past depositional model having points representing locations where the physical geological structures were originally deposited. An indication may be accepted to locally change the 3D transformation for a subset of sampling points in a first model of the models. The 3D transformation may be locally changed to fit the updated subset of sampling points. A locally altered or updated version of the first model and, e.g., second model, may be displayed where local changes to the first model are defined by the locally changed 3D transformation. The transformation may also be used to extract geobodies in the past depositional model.

  • Patent number: 10329888
    Abstract: The method and system describes monitoring and modeling the hydraulic fracturing of a reservoir. The microseismic events caused by hydraulic fracturing on a reservoir are captured by sensor arrays. The data captured by the sensor arrays are then analyzed to determine the source radius, and seismic moment tensor of microseismic events caused by the hydraulic fracturing. This information is then combined with a seismic velocity model to arrive at a discrete fracture network showing at least the orientation, source radius, and source mechanism of each microseismic event. This discrete fracture network is then used to determine the stimulated surface area, stimulated volume, and point of diminishing returns for the hydraulic fracturing process. Hydraulic fracturing engineers can use the algorithms to monitor the well and/or determine well completion.

    Abstract: Systems, methods and software can be used for processing microseismic data from a subterranean region. In some aspects, groupings of data points are identified. The data points are based on microseismic data from a subterranean region. The identification of the groupings is constrained such that each grouping includes at least a minimum number of the data points, and such that the data points in each grouping have at most a maximum extent of variation. In some instances, a histogram of the data points is generated, and each of the identified groupings corresponds to a bin in the histogram.
