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.

saturation occurs when a magnetic material is as magnetized as it can get.
No. THe zone of saturation is below the zone of aeration.
Yes, the zone of aeration is above the zone of saturation.
A saturation report is a personal narrative in a written article that conveys a sense of an experience that you have had. A saturation report should be accurate and personal but can be subjective, and written in the third person.

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.

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).
