  • Apparatus and method for determining the minimum miscibility pressure of a gas in a liquid
    Patent number: 4627273
    Abstract: An apparatus and method for determining the minimum miscibility pressure of a gas in a liquid comprises injecting a gas bubble into a transparent tube containing the liquid at a fixed predetermined pressure and temperature and observing the bubble behavior as it passes through the liquid in the tube. Thereafter, the pressure is increased and the procedure is repeated until the lowest pressure at which a bubble exhibits characteristic miscibility behavior in the liquid is determined, which is defined as the minimum miscibility pressure.

  • Method of determining the minimum level of gas enrichment for a miscible flood
    Patent number: 4621522
    Abstract: A method of determining the minimum level of enrichment required to render a substantially immiscible gas miscible in a liquid hydrocarbon by observing the behavior of enriched gas bubbles having incrementally increasing levels of enrichment as they rise through samples of liquid hydrocarbon. The lowest level of enrichment at which a bubble is observed to dissipate in the liquid hydrocarbon is the minimum level of enrichment.
