Residual oil saturation is oil saturation that can not be produced from an oil reservoir from gas or water displacement. It is usually considered the immobile oil saturation after conventional (gas or water displacement).
1) It is can be based on result from a laboratory test. A core sample (rock sample in the shape of a cylinder) is taken from a reservoir is first saturated with oil and then displaced (pushed out) with water or gas. The test is ended when no more oil can be produced from this core. The oil that can not be pushed out and remains in the core is termed "residual oil." The residual oil to gas displacement may be different from the residual oil from water displacement. The residual oil in this case is a laboratory estimate.
2) It can be based measurement made in a well. If a zone in a reservoir is producing only gas or water, it may be assumed that the oil has been completely displaced. In this case, special tools are lowered in the well and the oil saturation is determined. The residual oil in this case is a field estimate.
There are a number of unconventional means (or enhanced recovery techniques) to displace the residual oil. A common means is injection of carbon dioxide or an enriched gas at high pressures which can partially dissolve the residual oil.

What is a residual lake?
Lakes which are made by residual rocks which are left after weathering and erosion and form the residual lakes.
What is D 6 virgin fuel oil?
D6 virgin fuel oil is a type of residual fuel oil used in power plants and large ships that is produced from the refining of crude oil. It is a heavy, viscous oil with a high sulfur content, typically used as a fuel for industrial purposes.
Why are antioxidants used in crisps?
Because without them, the residual oil of the surface of crisps would react with oxygen from the air and give them a stale flavour.
What are some ways the us comsumes oil?
Some ways in which the U.S. consumes oil is for heating residential and commercial locations, fueling airliners, and residual fuel oils for factories and other industrial locations.
What is a residual haunting?
A residual haunting is a playback of a past event.
What is irreducible oil saturation?
Irreducible oil saturation is the residual amount of oil that remains trapped in the pores of a rock or reservoir even after water flooding or displacement with another fluid. It represents the minimum amount of oil that cannot be produced by conventional methods and is typically left behind in the formation.
