Abstract The increasing global demand for hydrocarbon has brought new challenges in the petroleum reservoir's drilling process. Non-biodegradable chemical additives are used fluid and it leads to endangering environment personnel safety. Thus, there is a great need biodegradable that can protect personal safety while done well. This study with help of microbial analysis investigates effects sit...

Objective(s):Astrodaucus persicus, Apiaceae, is used as vegetable or food additive in some parts of Iran. The essential oils of different parts of Astrodaucus persicus from Kordestan province were analyzed for the first time and compared with other regions. In this study, antioxidant activities and total phenols determination of aerial parts essential oils and root fractions of A. persicus were...

This study evaluated the effects of three commercial dispersants (Finasol OSR 52, Slickgone NS, Superdispersant 25) and biosurfactants (rhamnolipid, trehalolipid, sophorolipid) in crude-oil seawater microcosms. We analysed crucial early bacterial response (1 3 days). In contrast, most analyses miss this key period instead focus on later time points after oil dispersant addition. By focusing sta...

This study investigated the consequences of exposure to crude oil on components of the immune system of male rats. A total of 40 male albino rats were used for the experiment. Exposure to crude oil was achieved by oral administration of increasing doses (low, medium and high) of Nigerian Qua Iboe Brent crude oil to the rats every other day for 4 weeks. Haematological parameters, relative weight...

Oil reservoirs exhibit extreme environmental conditions such as high salinity and high temperature. Insights into microbial community assemblages in oil reservoirs and their functional potentials are important for understanding biogeochemical cycles in the subterranean biosphere. In this study, we performed shotgun metagenomic sequencing of crude oil samples from two geographically distant oil ...

this research studies the application of hybrid algorithms for predicting the prices of crude oil. brent crude oil price data and hybrid intelligent algorithm (time delay neural network, probabilistic neural network, and fuzzy logic) were used to build intelligent decision support systems for predicting crude oil prices. the proposed model was able to predict future crude oil prices from august...

The remediation of oil contaminated soils has been a major problem in oil producing countries and recently use of plants to clean such soils has been on investigation. In order to identify plants that can enhance the remediation of crude oil contaminated soil, the effect of the growth of G. max on the physico-chemistry and crude oil content of soil contaminated with different concentrations of ...

The activities involved in the production and exploration of crude oil has constantly polluted environment. This study investigated ability an indigenous fungus to utilize petroleum hydrocarbon. Response Surface Methodology was used optimize effects pH, microbial concentration (spores/ml), contact time (days) on removal efficiency refinery effluent. Monocillium sp. isolated for treatment efflue...

Fluctuations in crude oil price significantly impact the global economic market. A rise or a fall leads to redistribution of wealth in both oil-exporting and importing countries. Under such background, efficient and accurate predictions for crude oil price are critical for a stable economic development. However, crude oil price forecasting has been proved to be an extremely tough task, due to i...

Transportation of unrefined crude oil from the production unit to a refinery or large storage area by a pipeline is difficult due to the different properties of crude in various areas. Thus, the design of a crude oil pipeline is a very complex and time consuming process, when considering all the various parameters. There were three very important parameters that play a significant role in the t...
