The biomarker composition of biodegraded petroleum in an oil seep was determined using GC and GC MS techniques.
Due to the complexity of the composition of petroleum fractions and crude oils, it is not possible to measure or calculate accurately all of those properties.
Crude oil normally contains a varying composition of petroleum hydrocarbons, including benzene [ 16].
The composition of deep petroleum in petroliferous basins varies and includes gaseous hydrocarbon, condensate gas, condensate oil, liquid hydrocarbon, and oil gas coexistence.
In order to conduct complex research in oil that originated in Mongolia for further application of petroleum not only as fuel but also as raw material for organic synthesis, we need to study the physical and chemical characteristics, individual and group hydrocarbon's composition of main petroleum fractions.
The implementation of modeling techniques to simulate the molecular composition of petroleum feedstocks from routine analyses represents an alternative route towards molecule-based kinetic modeling.
The NP-HPLC stationary phases most commonly used for the determination of group composition of petroleum products were: silica gel [ 18], alumina, a mixture of silica gel and alumina [ 19– 21], Florisil [ 22], as well as bonded phases silica gel modified with cyanopropyl (CN) [ 23] or aminopropyl (NH2) [ 24].
The identity and composition of petroleum's countless molecular components is beyond the resolution of analytical techniques.
A number of studies and surveys on the physical and chemical characteristics, group hydrocarbon's composition of petroleum deposits in Zuun-Bayan, Sukhaibulag, Tsagaan Elst, Tamsagbulag have been carried out earlier through n-g-M, aniline point, dispersimetric methods successfully.
Moreover, this work attempts to highlight in simple manner how does the phase composition of petroleum fluids could be correlated with basic PVT parameters including bubble-point pressure, solution gas oil ratio (GOR) and oil formation volume factor (Bo). Experimental phase distribution measurements were conducted, in the present work, on two dead crude oil samples.
