  • Patent number: 9121968
    Abstract: Geologic information may be extracted from multiple offset stacks and/or angle stacks. Offset stacks and/or angle stacks may be received that represent energy that has propagated through a geologic volume of interest from energy sources to energy receivers. Attribute volumes associated with individual source-receiver offsets and/or source-receiver angles may be determined based on corresponding offset stacks and/or angle stacks. For individual offset stacks or angle stacks, corresponding sets of geologic features represented in the attribute volumes may be identified. The sets of geologic features corresponding to the different offset stacks and/or angle stacks to may be compared to determine discrepancies and/or similarities between the sets of geologic features corresponding to the different offset stacks and/or angle stacks. Stratigraphic interpretations, stratigraphic predictions, and/or other interpretations and/or predictions may be determined based on causes of the discrepancies and/or similarities.

  • Patent number: 9063246
    Abstract: Self-consistency and/or differences between volume images and interpreted spatial/volumetric context may be exploited for improving seismic imaging and estimation of attributes of geobodies, in accordance with one or more embodiments. Exemplary embodiments allow exploitation of positional and/or shape discrepancies and/or similarities of geobodies in image volumes associated with a geologic model of a geologic volume of interest to improve the accuracy of the geologic model and/or the image volumes. Constraints associated with the geologic volume of interest may be determined and/or utilized to confirm and/or specify dependencies between attributes that are potentially associated with individual geobodies.

  • Patent number: 8935068
    Abstract: A method of selecting a gear ratio of a transmission. The method includes measuring a current road grade with a sensing device and communicating the current road grade measurement to the controller. The controller receives a signal corresponding to a service brake input and determines a desired maximum acceleration limit of the vehicle. The method also includes calculating a predicted vehicle acceleration, measuring a current vehicle acceleration, and calculating an error value as a function of the predicted vehicle acceleration and measured vehicle acceleration. The method also computes an estimated required tractive braking effort and estimated tractive braking effort for at least one of N automatically selectable gear ratios of the transmission and selects one gear ratio of the N automatically selectable gear ratios for the operation of the transmission based on a comparison of the estimated required tractive braking effort and estimated tractive braking effort.

  • Patent number: 8843353
    Abstract: Embodiments of the present technology integrate seismic data and geologic concepts into earth model building. More specifically, exemplary embodiments provide new ways to build an earth model based on information in the seismic data and geologic concepts to use as a context to interpret the seismic data and/or to add to the earth model in regions where the seismic data is missing (e.g., either no data or no data resolvability). In some embodiments, a deterministic framework is generated for an earth models through deterministic identification of discrete geobodies. A hybrid deterministic-geostatistical earth model is generated by filling stratigraphic gaps in a deterministic framework using geostatistical information and/or seismic inversion, in accordance with some embodiments.
