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 Another name for oil the thick black liquid fossil fuel is?
petroleum, residual, crude, bitumen, asphalt among others.
Is the zone of saturation above the zone of aeration?
No, the zone of saturation is below the zone of aeration in the ground. The zone of saturation is where all spaces between soil particles are filled with water, while the zone of aeration is where there are air pockets between the soil particles.
When the air temperature increases the saturation vapor pressure?
When the air temperature increases, the saturation vapor pressure also increases. This means that warmer air can hold more water vapor before it reaches saturation. Conversely, cooler air has a lower saturation vapor pressure.
Is the zone of aeration above the zone of saturation?
Yes, the zone of aeration is located above the zone of saturation. The zone of aeration contains spaces filled with both air and water, whereas the zone of saturation is where all available spaces are filled with water.
What is saturation in magnetic materials?
Saturation in magnetic materials is the point at which the material can no longer be magnetized further, even with an increase in magnetic field strength. At saturation, all magnetic moments in the material are aligned in the direction of the magnetic field, and no additional magnetic flux can be induced.

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.

When hydrogen atoms are added to an unsaturated oil to cause more complete saturation it produces what?
The process of adding hydrogen atoms to an unsaturated oil to increase saturation is known as hydrogenation. This results in the formation of saturated fats, which are solid at room temperature.
What is true of any ferromagnetic materials?
It has an abnormally high magnetic permeability, it has a definite saturation point, and it has appreciable residual magnetism and hysteresis. That's why it remains magnetic even after the forcing magnetic field goes away.
Is there a method of extracting biopesticides from Jatropha crude oil?
Bio-pesticides are derived as residual bi-products after fermentation of the jatropha crude oil for biodiesel production

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 do you call the intensity or depth of a color?
The intensity or depth of a color is referred to as its saturation. Saturation describes how pure the color appears, with high saturation representing a vivid, intense color and low saturation indicating a more muted or washed-out appearance.
Why transformers take high input current at start?
Inrush current is a result of core saturation. The magnetic flux in the core of a transformer is 90 degrees out of phase with the voltage. Ideally the transformer switching device will be closed at a peak voltage, and the transformer core will have no residual flux from the last close. If this occurs, the flux in the core in the first cycle will be no larger than it normally would be. If the switching device closes at a zero voltage, or there is some residual flux, the transformer's core will be driven into partial saturation within the first cycle, unless it has been oversized to prevent saturation. Decreasing the applied voltage at energization will keep this from occuring. One method is to use pre-insertion resistors which cause a voltage drop to the transformer that is significant enough to prevent saturation within the first few cycles, and then they are removed. Another method is to de-engerize the transformer core, and close at voltage peaks only (controlled closing).
