  • Wellbore modeling
    Patent number: 9322259
    Abstract: A computer method, apparatus and system simulate hydraulic fracturing. The computer system/method models a wellbore of an injection well. The wellbore model includes a hydraulic drill pipe element in a borehole and related fluid flow in the borehole. The borehole workflow is modeled in a subject rock formation. A simulator operatively coupled to the model obtains pressure values from the modeled borehole workflow and modeled wellbore. The simulator automatically converts pore pressure from the modeled borehole into a mechanical pressure load on the subject rock formation. The mechanical pressure as hydrostatic pressure is automatically applied to the surface of the rock formation affected by the borehole and responsively defines one or more pressure induced fractures. A 2D or 3D graphical representation of the pressure induced fractures in the rock formation are displayed on output.

    Patent number: 9286415
    Abstract: A computer-implemented method for monitoring the progress of the implementation of a product design. A status representing the progress of the implementation is determined for each component of a first tree associated with the product design by first analyzing the components belonging to the lowest hierarchy level, the analysis being then conducted recursively on other components up to the highest hierarchy level, a component being analyzed by checking if an implementation link has been set up with a component belonging to a second tree associated with the product design and by checking the progress status of the children of the analyzed component.

  • Posture creation with tool pickup
    Patent number: 9256348
    Abstract: Computer simulation generates improved 3D images of human movement involving an object associated with the human character. A set of axes in 3 dimensional space is originally defined for tracking orientation of the human character in a 3D image. This set of axes is subsequently automatically applied to and used for object(s) carried by the human character. The object is displayed at a constant (same, unchanged) orientation while the human character is illustrated moving in certain ways in succeeding 3D images.
