Saturate, Aromatic, Resin and Asphaltene (SARA) is an analysis method that divides crude oil components according to their polarizability and polarity. The saturate fraction consists of nonpolar material including linear, branched, and cyclic saturated hydrocarbons ( paraffins ).
The PONA number is an index for oil components used to determine the paraffins (P), olefins (O), naphthenes (N) and aromatics (A) content [1] of FCC (fluid catalytic cracking) and coker gasoline. The PONA number plays a significant role in determining the quality of naphtha. Various grades of naphtha are produced depending on the PONA ...
Oil sampling is a procedure for collecting a volume of fluid from lubricated or hydraulic machinery for the purpose of oil analysis. Much like collecting forensic evidence at a crime scene, when collecting an oil sample, it is important to ensure that procedures are used to minimize disturbance of the sample during and after the sampling process.
The results of crude oil assay testing provide extensive detailed hydrocarbon analysis data for refiners, oil traders and producers. Assay data help refineries determine if a crude oil feedstock is compatible for a particular petroleum refinery or if the crude oil could cause yield, quality, production, environmental and other problems. [1]
The total acid number (TAN) is a measurement of acidity that is determined by the amount of potassium hydroxide in milligrams that is needed to neutralize the acids in one gram of oil. [1] It is an important quality measurement of crude oil. The TAN value indicates to the crude oil refinery the potential of corrosion problems.
2) and lubricant oil are miscible, i.e. form a single phase upon mixing. [1] [2] The value gives an approximation for the content of aromatic compounds in the oil, [2] since the miscibility of aniline, which is also an aromatic compound suggests the presence of similar (i.e. aromatic) compounds in the oil. The lower the aniline point, the ...

In terms of source rock analysis, several facts need to be established. Firstly, the question of whether there actually is any source rock in the area must be answered. . Delineation and identification of potential source rocks depends on studies of the local stratigraphy, palaeogeography and sedimentology to determine the likelihood of organic-rich sediments having been deposited in the
