  • Publication number: 20190213764
    Abstract: In some examples, a system may receive log data including a depth-series of data for a sensed parameter. The system may determine a parameter value of the depth series data for individual subunits of depth corresponding to a larger unit of depth. The system may further determine a scale of graphic effects corresponding to parameter values for the depth-series data. The system may present, on a display, a visualization of the depth-series data. For instance, the visualization may include a plurality of cells arranged in a plurality of rows, with each cell corresponding to the larger unit of depth and including a plurality of subcells corresponding to the subunits of depth. Additionally, each subcell may be presented with a respective graphic effect corresponding to the parameter value determined at a corresponding depth, and the graphic effect may correspond to the parameter value on the scale of graphic effects.

  • Patent number: 10202826
    Abstract: Systems and methods are directed to oil and gas management. In example implementations, data relating to oil and gas management is aggregated and placed in a cube along several cube dimensions, which can include scalar, temporal and spatial dimensions. The dimensions can be structured as a hierarchy, such that output can be generated as a roll up or roll down along the hierarchy.

  • Patent number: 9836449
    Abstract: The problem solved by this invention is to convert text information in a geology report to numerical values which reflects geological characteristics of a well's subsurface. Prior art referred above cannot be applicable to this problem. Since text information in the geology report is in the natural language form. This information is not widely used in this industry, due to the fact that the text information can be hardly extracted and summarized into numerical values and integrated into current physical geology models or statistical models. This invention makes the text information in geology report, which is often in a natural language form, easier to be integrated into current geology physical models or statistical models. Also, the numerical values extracted from the geology report can be integrated with other kinds of data, such as seismic data and well-logging data, to obtain more accurate and comprehensive analysis results.

  • Patent number: 9425958
    Abstract: A technique that binds encryption and decryption keys using a UID, a UDID, and a Pswd to a client mobile device in an enterprise. In one example embodiment, this is achieved by creating a new user account using the UID and the DPswd in an inactive state and communicating the UID and the DPswd to an intended user using a secure communication medium by an administrator. The intended user then logs into a cryptography key management system using the UID and the DPswd via a client mobile device. The UDID associated with the client mobile device is then hashed to create a H(UDID). The H(UDID) is then sent to the cryptography key management system by a local key management application module. The H(UDID) is then authenticated by the cryptography key management system. An encryption/decryption key is then assigned for the client mobile device.

  • Publication number: 20140039798
    Abstract: A system is disclosed comprising a non-transitory, computer-readable storage device storing software. The software, when executed by a processor, causes the processor to perform the following operations for each of a plurality of non-functional electronic devices: count a number of other non-functional electronic devices within a defined distance from the non-functional electronic device; and define the non-functional electronic device to be a core electronic device if the counted number is at least a threshold value, wherein threshold value is based on a total number of electronic devices within the defined distance around the non-functional electronic device. For each core electronic device, the software, when executed by a processor, further causes the processor to form a neighborhood group comprising the core electronic device and other non-functional electronic devices within the defined distance around the core electronic device.
