Anaerobic biodegradation of crude oil is one of the main mechanisms for the formation of
heavy oil and gas (referred to as crude oil degradation gas). With the Linfanjia area in the …

The geochemical characteristics of the existing natural gas in the Bohai Sea indicate that the
biodegradation gas of heavy oil is generally associated with heavy oil reservoirs, and its …

Two oils (one suffered obviously transformation, the other did not) from the Shengli oilfield
were selected for anaerobic biodegradation in laboratory. The oils with microbiological …

Biodegradation of crude oil in reservoirs has major economic consequences. While the
effects of biodegradation are empirically well known, the processes involved, the fraction of …

The enzymes and the characteristics of the community of the petroleum-degrading bacteria
play a crucial role in the crude oil biodegradation. The prediction of kinetics of the key …

The geochemical characteristics of oil and oil-dissolved gases in Yanmuxi Oilfield of Tuha
Basin were analyzed. The selectivity biodegradation of natural gas was studied. All of …

In this study, effective hydrocarbon degrading mixed bacteria (I strain) has been obtained by
screening, and three kinds of oil (Xi 5-P10, Sanyuanhou, G1131-262) from three different …

Biodegraded crude oils in China are distributed widely and make up a certain portion of
heavy-oil resources. An unresolved complex mixture (UCM) of hydrocarbons was isolated …

Due to multi-stage tectonic movements, many oil reservoirs in typical superimposed basins
of China have undergone more than one secondary alteration. Typically, these oil reservoirs …

Simulations of aerobic biodegradation have been widely employed to investigate the
mechanisms of crude oil biodegradation in geological environments. In this study, a …
