问答题 翻译:For an oil reservoir, as pressure decreases with production, a value is reached at which a portion of the liquid vaporizes to produce a gas phase that then exists in equilibrium with liquid.
问答题 翻译:The production rate of free gas at reservoir conditions is therefore the product of the difference (R - Rs) times the surface production rate of oil times the gas formation volume factorBg.
问答题 翻译:Their solubility is due to the elevated pressure and temperature existing underground.
