Abstract:

It is shown that the evolutionary-catagenetic model for calculating the initial potential hydrocarbon resources can serve as a scientific basis for the separate quantitative prediction of areas of oil-and-gas content. In this case retrospectively evaluated are the scales of generation and accumulation of hydrocarbons in the source rocks during catagenetic evolution of sedimentary basin. The authors propose a method, the results of evaluation of generation and accumulation scales and initial potential oil and gas resources for major oil-and-gas bearing complexes of Dzhebol stage.

Abstract:

The study of oil pollution is crucial nowadays and considered as one of the critical issues as oil pollution gives bad effects especially to wastewater treatment facilities. For that purpose, this study investigated the potential of activated carbon from biochars of textile sludge precursors for oil removal. The activated carbons were produced from biochar obtained through the pyrolysis of textile sludge waste by chemical activation with 1M of phosphoric acid which denoted as AC-B-H3PO4. Apart from that, the performance of adsorptive properties of the activated carbon was tested using simulate

Abstract:

The focus of our work is on anaerobic digestion of locally available agro wastes like coconut oil cake, cashew apple waste, and grass from lawn cuttings. The most productive agro waste, in terms of methane yield, was coconut oil cake and grass. The results showed that the initial volatile solids concentration significantly affected the biogas production. The methane yield from coconut oil cake was found to be 383 ml CH4/g VS and 277 ml CH4/g VS added at 4 and 4.5 g VS/l. In case of grass the biogas production increased with increasing VS concentrations with methane yield of 199, 250, 256, 284,

Here we tested the applicability of near infrared (NIR) spectroscopy for determining essential oil yield directly from wood powder. Essential oil from 139 wood powders was extracted via hydrodistillation. The measurements were based on the ratio between the extracted essential oil mass

The rate and level of depletion was dependent on the specific oil. Crude corn oil caused the most rapid and significant depletion; the final DO concentratio

Abstract:

ABSTRACT High resolution gas chromatography (GC) and gas chromatography in conjunction with mass spectrometry (GCMS) were used as fingerprinting techniques in this study to link oil spilled from the New Carissa to oil taken from oil impacted locations. Analyses included normal and isoprenoid alkanes, hopanes, and steranes, as well as a range of polynuclear aromatic hydrocarbons (PAHS). The oil spilled from the New Carissa was initially thought to be limited to bunker oils. Therefore, chromatograms of these samples and selected ion monitoring (SIM) chromatograms of the components and their comb

Conventionally, the knowledge of experts on the drilling features of a potential oil well is practically used to predict the volume of initial oil in place. Experts used different knowledge-based models such as volumetric, material balancing, analogy to predict the initial oil in place. In this study, 816 datasets were collected from Shell petroleum development company (SPDC) where the volumetric method is used for their prediction. These datasets were preprocessed and applied on two machine learning techniques of random forest and supervised vector regressor to predict the initial oil in plac

Abstract After a sandstone oilfield enters the high water-cut period, the viscosity of crude oil has an important influence on remaining oil distribution and waterflooding characteristics under the same factors of, e.g., reservoir quality and development methods. Based on a comprehensive interpretation of the waterflooded layers in new oil wells, physical simulation experiments, and reservoir numerical simulations, we analyzed the waterflooding laws of a high water-cut sandstone reservoir with different oil viscosities in Kazakhstan under the same oil production speed, and we clarified the rem

The current oil recovery of the Lucaogou shale oil reservoir is predicted to be about 7.2%.

The essential oil was evaluated for its in vitro potential phytotoxic activity against germination and initial radicle growth of Raphanus sativus L., Sinapis arvensis L., and Phalaris canariensis L. seeds. At 1.25 μg/mL and 0.625 μg/mL, the oil significantly promoted the germination of S. arvensis. Moreover, t

Recently, a non-invasive method of injecting magnetic/dielectric nanofluids into the oil reservoir was used for oil recovery application. The use of magnetic nanofluids in Enhanced Oil Recovery (EOR) has been reported to improve oil recovery. It is believed that the magnetic properties of nanoparticles (NPs) have a direct influence on the viscosity and wettability of nanofluid, and on oil-water interfacial tension (IFT). Thus, Mn0.5Zn0.5Fe2O4 (MnZn) ferrites may be a good candidate to be used in nanofluids for wettability alteration and oil-water IFT reduction due to their excellent magnetic p

Abstract Abrasive and adhesive wear is a major issue in sheet metal forming processes. Although different solutions exist to reduce its impact, there is still room for progress. Surface texturing presents a big potential for tribological behaviour improvement by introducing oil retention voids on the surface. However, the economic efficiency of the surface functionalization is paramount for its implementation in industrial processes. In the present study, a widely known technology, shot peening, is applied for the creation of the voids. A grinding+polishing process is then applied to ensure a

Observations of these spills help in understanding factors controlling the initial deposition and long-term fate of spilled oil in such locations. Gravel beaches are most common on rocky, glaciated coasts (Holocene and/or Pleistocene). For example, leading-edge coastlines in subpolar to polar regions, of which the Alaska coast is a prime example, may have gravel beach deposits along more than 50 percen

The potential of the bacteria to biodegrade various aromatic hydrocarbons was assessed using the 2,6-dichlorophenol-indophenol assay.
