  • Method and apparatus for core flooding studies
    Patent number: 5783760
    Abstract: An apparatus and process for observing fluid replacement in core samples while simulating subsurface reservoir conditions, including oil composition, temperature, fluid pressure, and overburden pressure. Overburden pressure is applied to a core sample placed in the apparatus, and the core sample is saturated with a core saturating fluid at a pressure greater than the bubble point pressure of the core saturating fluid. One or more replacement fluids are provided in fluid communication with the core sample and at the same pressure as the core saturating fluid pressure. The apparatus is placed in a centrifuge and spun, and the extent and rate of replacement of the core saturating fluid in the core by a replacement fluid can be observed.
    Type: Grant
