  • Patent number: 9551208
    Abstract: In some aspects, first and second boundaries are computed based on locations of microseismic events associated with a stimulation treatment of a subterranean region. Based on the first and second boundaries, an uncertainty associated with a stimulated reservoir volume (SRV) for the stimulation treatment is identified. The first and second boundaries are defined in a common spatial domain and at least a portion of the second boundary resides outside the first boundary.

  • Patent number: 9529104
    Abstract: In some aspects, a closed boundary is computed based on locations of microseismic events associated with a stimulation treatment of a subterranean region. Based on the boundary, a stimulated reservoir volume (SRV) for the stimulation treatment is identified. The boundary encloses a first subset of the locations and a second, different subset of the locations reside outside the boundary.

  • Patent number: 9529103
    Abstract: In some aspects, a first boundary is computed based on microseismic event locations associated with a first stage of a multi-stage injection treatment of a subterranean region. A second boundary is computed based on microseismic event locations associated with a second stage of the multi-stage injection treatment. Based on the first and second boundaries, an overlap between stimulated reservoir volumes (SRVs) associated with the first and second stages is determined.

  • Patent number: 9523275
    Abstract: In some aspects, a boundary is computed based on locations of microseismic events associated with a stimulation treatment of a subterranean region. A major axis of a stimulated reservoir volume (SRV) for the stimulation treatment is identified based on the boundary. In some examples, the boundary is an ellipsoid, and the major axis of the ellipsoid is identified.

  • Patent number: 9377547
    Abstract: Systems, methods, and software can be used to calculate fracture stratigraphy of a subterranean zone. In some aspects, microseismic event data associated with a fracture treatment of a subterranean zone are received, and the subterranean zone includes multiple subsurface layers. A filter is used to select a subset of the microseismic event data corresponding to fractures in a particular subsurface layer. Fracture stratigraphy is calculated for the particular subsurface layer from fracture planes associated with the selected subset of the microseismic event data.

  • Patent number: 9341727
    Abstract: Systems, methods, and software can be used to analyze microseismic data from a fracture treatment. In some aspects, fracture planes are identified based on microseismic event data from a fracture treatment of a subterranean zone. Each fracture plane is associated with a subset of the microseismic event data. Confidence level groups are identified from the fracture planes. Each confidence level group includes fracture planes that have an accuracy confidence value within a respective range. A graphical representation of the fracture planes is generated. The graphical representation includes a distinct plot for each confidence level group.

  • Patent number: 9285492
    Abstract: Systems, methods, and software can be used to identify fracture planes in a subterranean zone. In some aspects, data representing locations of microseismic events associated with a subterranean zone are received. Fracture plane parameters are calculated from the locations of the microseismic events. The fracture plane parameters are calculated based on a sum of weighted terms, and each of the weighted terms includes a weighting factor that decreases with a distance between at least one of the microseismic events and a fracture plane defined by the fracture plane parameters.

  • Patent number: 9268050
    Abstract: Systems, methods, and software can be used to determine a confidence value for a fracture plane. In some aspects, a subset of microseismic events associated with a fracture treatment of a subterranean zone are selected. Confidence in associating the selected subset of microseismic events with a common fracture plane is determined. The confidence can be determined, for example, based on the number of microseismic events in the subset, a location uncertainty for each microseismic event in the subset, a moment magnitude for each microseismic event in the subset, a distance between each microseismic event and a fracture plane fitted to the microseismic events, an orientation of the fracture plane fitted to the microseismic events, or a combination of these and other factors.

  • Patent number: 9176246
    Abstract: Systems, methods, and software can be used to identify properties of fractures in a subterranean zone. In some aspects, a basic plane orientation is determined for each of a plurality of basic planes. The basic planes are defined by coplanar subsets of microseismic event data from a fracture treatment of a subterranean zone. The quantity of the basic plane orientations in each of a plurality of ranges is calculated. In some implementations, a histogram is displayed to indicate the quantity of basic plane orientations in each of the orientation ranges. A dominant fracture orientation is identified for the subterranean zone based on one or more of the identified quantities.

  • Publication number: 20150057985
    Abstract: In some aspects, data for a new microseismic event associated with a stimulation treatment of a subterranean region is received. A boundary that was previously computed to enclose locations of prior microseismic events associated with the stimulation treatment is identified. The boundary is modified based on the data for the new microseismic event.

    Abstract: Systems, methods, and software can be used to analyze microseismic data from a fracture treatment. In some aspects, data for a new microseismic event are from a fracture treatment of a subterranean zone. An updated parameter for a fracture plane is calculated. The fracture plane was previously generated based on data for prior microseismic events. The updated parameter calculated is calculated based on the data for the new microseismic event and the data for the prior microseismic events. A graphical representation of the fracture plane is displayed based on the updated parameter.
