“…The amount of lighter hydrocarbons in the petroleum mixture significantly affects the subsurface composition and GOR values. In addition, these values can vary during oil migration due to different processes involved such as liquid-gas unmixing, hydrocarbon mixing, leaching by a gas phase or an aqueous solution, biodegradation, and gravity segregation (Taylor et al 1997;Larter et al 2000). All of these processes can be identified in oil-bearing petroleum inclusions as they entrap consecutive aliquots of migrating or charging fluids.…”

“…More recently, Yang et al [7] constructed the mathematical models to describe the occurrence of geotracers in migrated and reservoired oils. Similar abundances of isomers across the C 0 C 3 alkylphenol distributions in oils derived from a wide range of source rock types led Taylor et al [8] and Ioppolo et al [9] to suggest that the source-organic matter type of an oil is not an important factor in controlling the alkylphenol distributions. However, Lucach et al [5] found that initial alkylphenol distribution types in Omani oils differ from those in North Sea oils even though they are all derived from marine source rocks.…”

“…However, Lucach et al [5] found that initial alkylphenol distribution types in Omani oils differ from those in North Sea oils even though they are all derived from marine source rocks. Taylor et al [8] and Li et al [10] noted that oils derived from lacustrine source rocks have relatively low total alkylphenol concentrations compared to marine sourced oils, but no systematical record is available in literature to investigate the source facies controls on alkylphenol concentrations and homologue distribution. In present study we analyzed 60 oil samples from two lacustrine basins in east China where they have similar organic facies and maturity level.…”

Oils from two lacustrine rift basins in east China are thoroughly investigated using geochemical method to understand controls on alkylphenol occurrence and distribution in oils. Oils in the Lujiapu Depression, Kailu Basin are derived from the Cretaceous source rocks, and those in the Dongying Depression, Bohai Bay Basin, from the Tertiary source rocks. All oils are experienced relatively short distance of migration and have similar maturity in each basin. Differences in homologue distributions from different oilfields are most likely caused by organic facies variation of source rocks. The oils in the Lujiapu Depression are characterized by high proportion of C 3 alkylphenols (prefixes refer to the number of alkylcarbons joined to the aromatic ring of the phenol molecule) and low proportion of cresols and C 2 alkylphenols compared to oils from the Dongying Depression. Alkylphenol isomer distribution is possibly affected by depositional environment especially for C 3 alkylphenols. Dysoxic freshwater environment is favorable for the formation of propyl or isopropyl substituted C 3 alkylphenols, while highly reducing saline water is more suitable for trimethyl substituted C 3 alkylphenols. Variations in alkylphenol concentrations within a petroleum system are controlled mainly by secondary migration processes with alkylphenol concentrations decreasing along migration direction. Interestingly, coupled with geological factors, a subtle change of alkylphenol concentrations can be applied to differentiate carrier systems. When oil migrates through sandy beds, concentrations of total alkylphenols decrease dramatically with migration distance, while such change is less significant when oil migrates vertically along faults. However, most isomer ratios potentially related to migration distance are not as effective as those alkylcarbazoles in migration diagnosis due to complicated affecting factors.

“…Mit Ausnahme des 3-n-Propylphenols sind alle SCAP in verschiedenen Erdölen nachgewiesen (Ippolo et al 1992, 2007, Bastow et al 2003, Taylor et al 1997. Trotz stark variierender SCAP-Konzentrationen zwischen keinen und mehreren 10.000 ppm in verschiedensten Rohölen (unterschiedliche Entstehungsorte und -zeiten, Ursprungsmaterialien und Alterierungsgrade), zeigen alle Rohöle einer Versuchsreihe äquivalente Isomerenverteilungen unter den C 0 -C 2 Isomeren; lediglich bei den C 3 -Isomeren zeigten sich Unterschiede im Phenolmuster (Taylor et al 1997). SCAP werden als effektive Indikatoren für Migrationsprozesse von Erdölen beschrieben.…”

Sources and occurence of short chained alkyl phenols (SCAP)Abstract A literature research and own data on Short Chain Alkyl Phenols (SCAP) in the environment indicate that treatment of solid fossil fuel materials and the production of chemicals from various industries have common potenzial anthropogenic sources of SCAP compounds in the environment. Potenzial natural sources of SCAP in the environment are solely from petroliferous rocks. A wide range of SCAP applications for different industries is summarized here briefly. Many process-based inputs to the environment have been identified. Contaminations have specific "fingerprints", (unique types of SCAP compound occurrences). This enables the identification of SCAP sources. Furthermore, unique environmental properties among the variety of SCAP compounds, facilitates characterisation of contaminated sites. Knowledge of the unique SCAP "fingerprints" in conjunction with the environmentally predictable relationships of the various SCAP compounds is the basis for the use of these substances in process and flow characterisation within aquifers.
