In Measurements of Supersaturation and Critical Gas Saturation'' (SPE Formation Evaluation, Dec. 1992, Page 337) Firoozabadi et al. reported that several expansion solution-gas-drive experiments at pressure-decline rates much higher than usually occur in actual reservoirs terminated at the onset of gas production.'' For this reason, they neither envisaged a gas/oil separator for measuring the GOR evolution, which is an important parameter for establishing critical gas saturation, S[sub gc], nor allowed sufficient pressure decline to measure the evolution of upward gas migration to confirm their low measured S[sub gc]. This confirmation was needed because their results contradict those of Dumore, Madaoui, and Moulu and Longeron.
