(DBE 1 to 36, AMM 580). The molecular composition and the interactions between
all the oil constituents are responsible for the physicochemical properties of an oil
under given pressure and temperature conditions. Important physicochemical oil
properties will be discussed in the following sections.
3.2 Physical Properties of Oil Under Deep Ocean Conditions
In order to reflect the real situation in the oil reservoir, the production well, and possible events like oil spills or emergency shutdowns, the properties of the so-called
live fluids shall be taken into account. Under reservoir, deep-sea, or production conditions, commonly a certain amount of gas is present in the coexisting petroleum
liquid and aqueous phases. The bubble point of a live oil resembles the saturation
pressure below which a gas phase theoretically separates from the hydrocarbon liquid. Live oils may be sampled directly from the field or may be recombined in the
laboratory from dead oil and the respective gas mixture knowing the bubble point
