  • Publication number: 20240141766
    Abstract: A bidirectional self-regulating chemical flooding method and system for enhancing oil recovery includes: determining the average particle size of dispersed phase droplets under stable seepage flow of an oil-in-water emulsion according to the average reservoir permeability; determining injection concentration of an emulsifier which matches a target reservoir according to reservoir seepage velocity; under a condition of keeping the injection concentration of the emulsifier constant, determining the optimal injection concentration of a polymer which matches the injection concentration of the emulsifier through core flooding experiments with the maximum equivalent ton oil accumulation as a target; determining total injection amount of the emulsifier and total injection amount of the polymer for implementing well group units; and optimizing injection amount of the emulsifier and the polymer in each single well by using a numerical simulator of a chemical flooding reservoir.

  • Patent number: 8577895
    Abstract: Contacts lists are dynamically managed in association with communication and collaboration applications and devices. Automated and user defined factors are determined based on information from various resources such as user profile, contact information, past communication information, application/device types, and comparable ones. Factors may be weighted and employed to prioritize contacts lists under different circumstances. Prioritized contacts lists may be provided to a user, stored, updated, or otherwise processed.
