High-density polyethylene pipes are prevailing in transportation of combustible natural gases, so their reliability deserves special attention. Amongst the diverse ageing effects that are usually taken into account, including internal pressure,…
Accidental release of petroleum in the Arctic is of growing concern owing to increases in ship traffic and possible future oil exploration. A crude oil-in-sea ice mesocosm experiment was conducted to identify oil-partitioning trends in sea ice and…
The prediction of ageing phenomena in Liquefied Natural Gas is based on two hypotheses: considering evaporation rate or considering heat flow transferred to the hydrocarbons mixture. This paper proposes two models based on these premises and…
Iron (Fe) isotope is an effective tool for tracing Fe transformation, migration, and biogeochemical cycling in the Earth's surface system. In this study, the Fe content and stable isotope composition (56Fe/54Fe) in two Gleysol profiles (M1 and M2)…
Photooxidation was an important weathering process for spilled oil at the water surface following the Deepwater Horizon oil spill, leading to the rapid formation of polar or oxygenated hydrocarbons, or photo-generated asphaltenes. While the great…
Igneous rocks in deep basins are important unconventional petroleum reservoirs. Storage space and porethroat structure of igneous rocks are crucial to be considered as effective reservoirs. There developed large-scale petroleum reservoirs in the…
We present a solid-phase extraction method followed by derivatization with a charged tag to characterize ketone/aldehyde-containing functionalities (proposed photo-oxidation transformation products) in weathered petroleum by Fourier transform ion…
The characterization, occurrence, fate and behaviour of spilled oil in the affected boreal freshwater ecosystem were investigated in this study following a spill in March 2015, in Gogama, Ontario, Canada. A physicochemical property analysis of the…
The Cambrian weathering crust formed in the Lower Paleozoic central paleouplift of the Ordos Basin and its periphery has always been a key target for oil and gas exploration in this basin, and important breakthroughs in oil and gas exploration have…
Accidental release of petroleum in the Arctic is of growing concern owing to increases in ship traffic and possible future oil exploration. A crude oil-in-sea ice mesocosm experiment was conducted to identify oil-partitioning trends in sea ice and…
Oil degradation by surface-level atmospheric ozone has been largely ignored in the field. To address this knowledge gap, this study investigated the ozonation rate and extent of typical petroleum compounds by simulated surface-level ozone, including…
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…
The weathering of crude oil at sea has been researched for nearly half a century. However, there have been relatively few opportunities to validate laboratory-based predictions about the rates, relative importance, and controls of oil weathering…
The characterization, occurrence, fate and behaviour of spilled oil in the affected boreal freshwater ecosystem were investigated in this study following a spill in March 2015, in Gogama, Ontario, Canada. A physicochemical property analysis of the…
High-density polyethylene pipes are prevailing in transportation of combustible natural gases, so their reliability deserves special attention. Amongst the diverse ageing effects that are usually taken into account, including internal pressure,…
A method was developed for classifying petroleum into four types according to their origin and integrity: marine, non-marine, degraded and thermally transformed. The method was based on the relative proportions of functional groups measured by FTIR…
Through the Deepwater Horizon oil spill accident in 2010, around 7.000 m3 of chemical dispersants were applied to a subsea blowout until the release of crude oil to the environment was ended. Since then, chemical dispersion has become one of the…
Jiaozhou Bight is a semi-closed embayment, located on the eastern coast of Jiaodong Peninsula. Qingdao Port located in the bight is one of the largest transportation trade and professional crude oil transportation ports in China. Potential oil spills…
