When oil is produced to surface temperature and pressure it is usual for some natural gas to come out of solution. The gas/oil ratio (GOR) is the ratio of the volume of gas ("scf") that comes out of solution to the volume of oil — at standard conditions. In reservoir simulation gas/oil ratio is usually abbreviated .
Ethanol fuel mixtures have "E" numbers which describe the percentage of ethanol fuel in the mixture by volume, for example, E85 is 85% anhydrous ethanol and 15% gasoline. Low-ethanol blends are typically from E5 to E25, although internationally the most common use of the term refers to the E10 blend.
n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [4]
The composition of a gasoline depends upon: the oil refinery that makes the gasoline, as not all refineries have the same set of processing units; the crude oil feed used by the refinery; the grade of gasoline sought (in particular, the octane rating). The various refinery streams blended to make gasoline have different characteristics.
It may be obtained from the heavy gas oil cut, [7] or it may be a blend of residual oil with enough number 2 oil to adjust viscosity until it can be pumped without preheating. [8] This fuel is sometimes known by the Navy specification of Bunker B. Number 6 fuel oil is a high-viscosity residual oil requiring preheating to 104–127 °C (219 ...
Gasoline prices go from 36 cents a gallon in 1972 to over 50 cents a gallon in 1973. March 18, 1974 - At an OPEC meeting, seven members lift the ban on exports to United States.
In a fluid mixture like a petroleum gas or oil there are lots of molecule types, and within this mixture there are families of molecule types (i.e. groups of fluid components). The simplest group is the n-alkanes which are long chains of CH 2-elements. The more CH 2-elements, or carbon atoms, the longer molecule. Critical viscosity and critical ...
Petroleum products are materials derived from crude oil as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure organic compounds, petroleum products are complex mixtures. [1] Most petroleum is converted into petroleum products, which include several classes of fuels. [2]
