  • DETERMINATION OF AN ACTUAL OPTIMUM SALINITY AND AN ACTUAL OPTIMUM TYPE OF MICROEMULSION FOR SURFACTANT/POLYMER FLOODING
    Publication number: 20090194276
    Abstract: Systems and methods for the determination of an optimum salinity type and an optimum salinity of a surfactant microemulsion system are shown. Optimum salinity type and optimum salinity in surfactant/polymer flooding is determined, according to embodiments, by core-flood experiments so that a variety of multiphase flow parameters such as relative permeability and phase trapping that affects oil recovery factor, influences the determination of the optimum salinity type and optimum salinity. The optimum salinity determined from this approach preferably corresponds to the highest oil recovery factor.

  • MICROWAVEABLE NESTED TRAYS
    Publication number: 20090184025
    Abstract: One embodiment includes a package system containing a main container with a smaller container nested in it. The smaller container is filled with a secondary food item designed to be mixed into the primary food item. The smaller container is placed within the main container. The area of the main container not occupied by the smaller container includes a main food item. Both containers are sealed with one film. Before consumption, a consumer will place the package in a microwave to heat. Once heated, the smaller container is removed from the main container, creating space in the main container previously occupied by the smaller container. The main food item in the main container will re-position creating space between the top of the main food item to the edge of the main container. The secondary item can be added into the main container without overflowing out of the main container.
