    摘要: A game including a game board with a game travel path defined thereon, a game token moveably placeable on the game travel path, and a move generator associated with the game comprising numbers, mathematical operators, mathematical operations, variables, and variable values. A method of constructing a move includes forming the mathematical expression components into a mathematical expression to yield a movement value, and then moving the game token along the game travel path according to rules of the game for the movement value.

    摘要: This invention provides a method and an apparatus for fiber optic tomographic analysis and imaging of fluids. This invention includes a method for providing information on downhole fluid flowing in a hydrocarbon well, utilizing at least one downhole tomograph chamber (10). Light is introduced into the tomograph chamber (10) by an optical fiber bundle (24), and portions of the light are collected in other optical fiber bundles (32, 34). The collected portions of light are conveyed through the optical fiber bundles (32, 34) to a surface system (14), where the light is detected to produce signals proportional to the portions of light to provide information on optical properties of downhole fluid flowing in the well. This invention allows the generation of two or three dimensional images of multiple phase flow in the wellbore and allows determination of production parameters of multiple zones on an individual zone basis.
