Contamination derived from maritime transportation is not only linked to petroleum-based substances but also to transportation of other substances such as hazardous and noxious nature (HNS). Over the last decade, the maritime trade of HNS has been…
The U.S. Geological Survey assessed undiscovered unconventional hydrocarbon resources reservoired in the Upper Cretaceous Tuscaloosa marine shale (TMS) of southern Mississippi and adjacent Louisiana in 2018. As part of the assessment, oil-source rock…
Investigation on the use of diamondoids to assess the extent of thermal maturity, depositional environment, and origin of Niger Delta source rocks was carried out. This was done to evaluate the significant of diamondoids in petroleum exploration in…
Myanmar has a long history of petroleum production, but little information has so far been published pertaining to the detailed composition of the country's oils. The present paper reports the results of the analysis of a total of 28 Cenozoic oil…
Large volumes of black and volatile oils have been recently discovered from 7000 m to 8400 m below surface in the Tarim Basin. Diamondoids, compounds recalcitrant to thermal stress, have been applied to estimate the extent of oil-cracking, but…
The study employed thirteen (13) crude oil samples from thirteen (13) producing wells, with the aim of examining the source of organic matter and the paleoenvironment of deposition. The crude oils were deasphaltened and the maltene fraction…
Oil contamination is an environmental issue of great concern and the necessity for background studies and monitoring programs to continuously evaluate the levels of oil pollution is required. In this study, Atlantic cod (Gadus morhua) were exposed to…
Abstract: Relationships of the distribution of petroleum biomarker hydrocarbons (biomarker HCs), namely, n-alkanes, isoprenanes, n-alkylcyclohexanes, steranes, terpanes, and n-alkylbenzenes, in the soluble fraction and in thermolysis products of the…
A systematic study into the origin and potential formation processes of condensates in the Pinghu Slope Belt of the Xihu Depression, East China Sea Basin, was conducted using fluid inclusion analysis, petroleum geochemistry, and rock gold-tube…
In recent years, great breakthroughs have been achieved in the exploration of Shaximiao Formation tight gas in Jinqiu Gas Field in central Sichuan-western Sichuan transition zone, and multi-stage gas rich sandstone formations have been discovered…
We established the generation and migration processes as well as the influence of secondary processes of oil and natural gas accumulated in Lower Cretaceous-Oligocene strata of the western part of the Ukrainian Outer Carpathians based on the results…
This paper studied the origin and the maturity of the Jurassic subsalt condensate in the northeastern margin of the Amu Darya Basin and analyzed its formation condition and mechanism through conducting geochemical analysis of biomarkers, carbon…
Crude oil and its derivatives are primary energy resources for humans, and processes involving these materials could affect aquatic environments. Acetyl cholinesterase (AChE) activity is a suitable biomarker for exposure to organophosphate…
Hydraulic fracturing is routinely used to stimulate unconventional reservoirs. In the Niobrara shale oil play there are several fracking targets, but the actual stimulated rock volume is not well constrained. This means that allocating produced oil…
In this study a novel sustainable method based on supercritical fluid extraction (SFE) method was developed for simultaneous extraction and fractionation of petroleum biomarkers. We herein proposed a two-step supercritical fluid extraction method for…
The Peace-Athabasca Delta (PAD) receives a mixture of hydrocarbons from biogenic, pyrogenic, and petrogenic processes. Source apportionment in the PAD has focussed on polycyclic aromatic compounds (PACs), which are ubiquitous in the environment and…
Crude oil and its derivatives are primary energy resources for humans, and processes involving these materials could affect aquatic environments. Acetyl cholinesterase (AChE) activity is a suitable biomarker for exposure to organophosphate…
The origin, migration pathways, and the influence of secondary processes of oil and natural gas accumulated in Lower Cretaceous to Lower Miocene strata of the central part of the Polish Outer Carpathians are investigated based on organic geochemical…
This paper presents the first detailed organic geochemistry and petrography of the Lower Cretaceous tight reservoir units from the Valdemar Field, Danish Central Graben. The Tuxen and Sola formation chalks and the interbedded argillaceous Munk Marl…
The oil-bearing fluid inclusions (FIs) in reservoir sandstones in the Skarv field in the Haltenbanken region offshore Norway recorded a complex oil charge and leakage history. Inclusion oils, hosted in quartz cements, and corresponding adsorbed…
The relationship between fluid physical properties and hydrocarbon compositions was investigated on a suite of eleven heavy oil samples from the Orcutt Field, onshore Santa Maria Basin in California. The physical properties of oils display a…
Determining the thermal maturity and the charge history of crude oil to any reservoir, has key implications for understanding petroleum generation, accumulation history and hence identification of exploration potential. In this paper we combine…
Oil and derivatives are essential to supply human demand for energy. Despite the significant increase in security measures to avoid accidental spills, the impacts of these pollutants to the aquatic environment are still substantial. It is therefore…
The hydrocarbon migration and accumulation process in the Kuqa Depression are complex. In recent years, the Jurassic strata have recorded hydrocarbon discoveries in the Tugerming area of the eastern Kuqa Depression. However, it is a new exploration…

Maritime trade and transportation of hazardous and noxious substances (HNS) have been increasing in European waters, augmenting the risk of accidental spills from ships or in harbours. Despite their reported toxicity and hazardousness, information on…
Previous studies have found that alkylated polycyclic aromatic hydrocarbons (alkyl-PAHs) were more abundant in petrogenic sources (e.g., crude oil and its refined products) than pyrogenic sources of incomplete combustion. While urinary hydroxylated…
The long-term fate of three groups of petroleum biomarker compounds (terpanes, steranes, and triaromatic steranes) was investigated in the Deepwater Horizon (DWH) oil spill residues collected from Alabama (USA) beaches over the past 10 years. This is…
