  • Reservoir regions management with unstructured grid reservoir simuation model
    Patent number: 11379640
    Abstract: Reservoir management based on unstructured grid reservoir simulation is improved with machine learning based intelligent automation. Reservoir heterogeneity, geological internal boundary features and well geometry complexity are taken into account to automatically detect well zone and focusing reservoir area by calculating the region-of-interests in the model and defining cell spacing for grid coarsening and refinement in the reservoir. Data points for wells in the reservoir are grouped into reservoir regions according to datasets organized as a convex hull, which is a minimum convex set in spatial geometry which encloses the totality of such data points. The reservoir regions form a basis for grid spacing utilized in the reservoir model.

  • Dynamic bit line voltage and sensing time enhanced read for data recovery
    Patent number: 11250917
    Abstract: A method and system are provided for reading a non-transitory memory array. When a default read operation is performed and has failed, a dynamic sensing bit line voltage (VBLC) enhanced read or a dynamic sense time read is performed. According to the dynamic VBLC enhanced read or the dynamic sense time enhanced read, the VBLC or the sense time is increased, and a read is performed with the increased VBLC or increased sense time. If this enhanced read is unsuccessful, and if a maximum VBLC or a maximum sense time has not yet been reached, the VBLC or the sense time is increased again, and another read is performed. Once the maximum VBLC or a maximum sense time has been reached, if the read is still not successful, a read failure is reported.
