Characterization of high molecular weight biomarkers in crude oils
High-temperature gas chromatography (HTGC) has enhanced our ability to characterize hydrocarbons extending to C120 in crude oils. As a result, hydrocarbons in waxes (> C20) have been observed to vary signi®cantly between crude oils, even those presumed to originate from the same source. Prior to this development, microcrystalline waxes containing hydrocarbons above C40 were not characterized on...
متن کاملCharacterization of Petroleum Crude Oils using Laser Induced Fluorescence
The use of laser induced fluorescence (LIF) spectroscopy to characterize crude oil has privileges compared to conventional techniques in terms of reducing the size of sample, rapidity of measurements, high sensitivity and simplicity of sample handling and possibility of in situ measurements. The fluorescence radiation emitted from crude oil is the result of the interaction between the aromatic ...
متن کاملCharacterization and Evaluation of Light Hydrocarbon in Northwestern Iranian Crude Oil by Detailed Hydrocarbon Analysis (D.H.A)Gas Chromatography
Lighthydrocarbons are commonly used to evaluatecrude oils to determine oil families in reservoirs undergone some kind of alteration process. In this study crude oil contentsfromNorthwestern IranDelta (samples A, B and C)were analyzed in order to evaluate the IranDelta petroleum system independent of higher molecular weight markers. Ultra high resolution gas chromatography was used in separation...
