Abstract:

AbstractAs one of the most petroliferous oil producing area in Kuqa depression, Dawanqi (DWQ) oilfield is supplying with great attention. In this regard, the geochemical characteristics and oil families from DWQ field were investigated using molecular compounds analysis of GC, GC–MS techniques. The bulk geochemistry of oils from DWQ oilfield displays complicated molecular composition characteristics, including relative higher indices of Pr/Ph (1.4 ~ 4.26, with an average of 2.4), high concentration of light hydrocarbons and certain abundant pentacyclic triterpene and steranes.

Abstract:

Tricyclic terpanes identified in two representative crude oils from the Central and Western Niger Delta (oil- RVAG and oil-DTIR, respectively) ranged from C19 to C29, including C24 tetracyclic terpane. Plot of the abundances of tricyclic terpanes show similarity in the distribution profile of the oil samples, characterized by the uncommon distribution of C20 and C21 tricyclic terpanes indicating both Niger Delta crude oils are derived from similar source organic matter. Ratios of C22/C21 and C24/C23 tricyclic terpanes indicate source rocks of the crude oil samples were deposited in a deltaic e

<strong>Abstract:</strong> Gas chromatography system equipped with a mass selective detector was employed for chemical fingerprinting of two Niger Delta crude oils (samples A-001 and F-100) and their mixtures (samples B-208, C-406, D-604 and E-802) at different proportion. Total and individual abundances of C<sub>19</sub> to C<sub>29 </sub>tricyclic terpanes, including C<sub>24</sub> tetracyclic terpane, detected in the six oil samples followed similar patterns, A-001 < E-802 < F-100 < B-208 < C-406 < D-604, indicating the abundances did not mix correspondingly with the proporti

Abstract:

Ma2 and Ma3 hydrocarbon source rock samples from the Fengcheng Formation in well Maye 1, Mahu Depression, Junggar Basin, were studied using conventional geochemical analysis methods and saturated hydrocarbon gas chromatography–mass spectrometry. The distribution patterns, abundance, relative content, and ratios of different carbon compounds of tricyclic terpane in hydrocarbon source rocks from fresh-to-mildly-saline (type I), moderately saline (type II), and saline (type III) water environments significantly differed. The C28–C29TT/C30H and C19–C29TT/C30H ratios were the lowest in the type I h

Abstract:

In order to study the distributions of the biomarker of the continental source rocks in the Sichuan Basin, 71 source rock samples were collected from the Upper Triassic-Lower Jurassic strata in different regions. The n-alkanes, isoprenoids, terpane, sterane, sesquiterpenes, caranes and aromatics in the extracts were analyzed in detail. GC-MS analysis has been conducted to analyze the biomarker of the continental source rocks. The results of GC-MS analysis indicate that the Upper Triassic source rocks are high in the content of extended tricyclic terpanes, pristane, phytane, gammacerane, C28 re

Abstract:

C20 and C21 tricyclic terpanes were investigated in crude oils from Niger Delta, Nigeria. From comparison of the mass chromatograms (m/z 191) of two crude oil samples (CEN-21 and WST-69) with related literatures on tricyclic terpanes which eluted from the gas chromatography (GC) within certain retention time, 12 peaks were selected. Peaks 1 - 5 were selected as C20 tricyclic terpane isomers (TR20a-e) and peaks 6 - 12 selected as C21 tricyclic terpanes (TR21a-g). This distribution is usually as crude oils show a single peak each and indicate the distribution of C20 and C21 tricyclic terpanes in

Abstract:

Eight cuttings samples were obtained from Sargelu and Kurrachine formations in different wells at different depths to detect steranes and triterpanes biomarkers as an indicator of the depositional environments and thermal maturity of organic matter. This was accomplished using GC-MS technology. The diasterane/sterane ratio showed low ratios in analyzed samples (BJS2, JKS3, BJK1, JKK4, JKK7) as in most marine carbonate sources, while algal-bacterial organic matter contribution for the samples analyzed based on the predominance of C23 tricyclic relative to the C19 tricyclic terpene and the C23 t

Abstract:

The Tarim Basin, a significant region of coal-derived gas generation in China, has widely dispersed coal measure source rocks, especially in the Kuqa Depression. The typical coal measure strata from the Kuqa River and Kapushaliang River sections in the Kuqa Depression were systematically sampled. According to a conventional geochemical analysis (including materials and lithology), a total of 25 typical coal measure source rock samples were chosen for chromatography and chromatography–mass spectrometry examination. It was demonstrated that there were significant discrepancies in the coal source

Abstract:

Several billion-ton Neogene oil fields have been successfully discovered in the middle Huanghekou sag over the past few years. However, the source of the crude oil needs to be clarified, and the relevant oil-source correlation was less carried out. Six source rocks of the third member of the Paleocene Shahejie Formation (Es3) from five wells and sixteen Neogene crude oil samples from nine wells in the middle Huanghekou sag were investigated for the oil-source correlation with the biomarkers and carbon and hydrogen isotopes of saturated hydrocarbon monomers.
