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.
