Undersaturated oil reservoir wikipedia
Take a look at the phase envelope. If the reservoir pressure is at point 1 then that reservoir is an undersaturated oil reservoir. What this means is that the reservoir pressure (point 1) is higher than the bubble point pressure. The bubble point pressure (on the bubble point line) is a very important concept for every oil reservoir.reservoir evaluation in undersaturated oil reservoirs using modern production data analysis; a simulation study Finally, the upwelling of water that is undersaturated in aragonite from the halocline of the Arctic Ocean (Mathis et al. undersaturated oil reservoir wikipedia
Reservoir Classification is determined by the reservoir fluids phase behavior. They are classified into four reservoir types: single phase gas, gas condensate, undersaturated oil and saturated oil
Oil reservoirs If the reservoir temperature T is less than the critical temperature Tc of the reservoir fluid, the reservoir is classified as an oil reservoir. Gas reservoirs If the reservoir temperature is greater than the critical temperature of the hydrocarbon fluid, the reservoir is considered a gas reservoir. A petroleum reservoir or oil and gas reservoir is a subsurface pool of hydrocarbons contained in porous or fractured rock formations. Petroleum reservoirs are broadly classified as conventional and unconventional reservoirs. In case of conventional reservoirs,undersaturated oil reservoir wikipedia Oil compressibility is a source of energy for fluid flow in a reservoir. In an undersaturated reservoir, it is a dominant drive mechanism, but for a saturated reservoir, it is overshadowed by gas compressibility effects due to the evolution of dissolved gas.
