A further limitation in oil–oil correlations exists when migrating gas dissolves part of a crude oil at depth (i.e., at high pressure) and exsolves a portion of its oil components at shallower depths (i.e., at reduced pressure). Because each component of petroleum is soluble to a different degree in natural gas, this solution-exsolution process can radically alter the oil composition and the appearance of gas chromatograms.
