Abstract:

Abstract Any crude oil with an API gravity below 20 is considered heavy crude, and crude oil with an API gravity below 10 is considered extremely heavy. Conventional oil is lighter and less dense than unconventional oil resources such as heavy oil, extra-heavy oil, and bitumen. When the world’s conventional crude oil stocks are depleted, heavy oil resources will be well-positioned to continue satisfying demand for petroleum products. The economic viability of heavy oil depends on its quality being increased. The use of a catalytic steam injection in-situ upgrading technique to improve heavy oi

Production of heavy and extra-heavy crude oils generally entails high costs, especially in the winter season, due to heat losses.

The observed results indicate a non-linear decreasing behavior of viscosity concerning temperature and volume fraction of the viscosity reducer.

By analyzing over 3140 documents, only a final total of 42 previous peer-reviewed articles were considered, where 58% sought to understand and optimize water flow from the reservoir to t

Abstract:

Transportation of heavy crude oil through closed pipelines is a challenging issue both in offshore and in land oil transportation. The scope of the present paper deals with the computational modelling of two phase extra heavy crude oil & water flow in OpenFOAM. In order to validate the flow model the pressure variation along the length of the channel are investigated, which shows the typical plot of two roughly constant pressure lines at different levels connected by a sharp change of pressure at the interface of two fluids. The validated flow model, aims at optimizing the kinematic viscos

Abstract:

White-rot fungi remain dynamic to an extensive series of materials using their extra-cellular lignin-modifying enzymes that has a low substrate-specificity. This study is aimed at evaluating the ability of Pleurotus pulmonarius LAU09 (JF736658) to biodegrade and utilize crude oil contaminated substrate. Substrates for mushroom cultivation were prepared by mixing sawdust, CaCO3, NPK fertilizer and wheat bran at ratio of 200:1:2:3 for each crude oil concentration (0.4%, 0.8%, 1.2%, 1.6%, and 2%) used. A significant difference was observed in the Total Petroleum Hydrocarbons (TPH) of the substrat

Abstract:

Summary Application of cyclic solvent injection into heavy and viscous crude oil followed by in-situ combustion of heavy residues is explored from a laboratory perspective. The solvent reduces oil viscosity in-situ and extracts the lighter crude-oil fractions. Combustion cleans the near-well region and stimulates thermally the oil production. Both solvent injection and in-situ combustion are technically effective. The combination of the two methods, however, has never been tried to our knowledge. Hamaca (Venezuela) and West Sak (Alaska) crude oils were employed. First, ramped temperature oxida

Abstract:

CO2 and N2 injection is an effective enhanced oil recovery technology in the oilfield especially for low-permeability and extra low-permeability reservoirs. However, these processes can induce an asphaltene deposition during oil production. Asphaltene-deposition-induced formation damage is a fairly severe problem. Therefore, predicting the likelihood of asphaltene deposition in reservoir conditions is crucial. This paper presents the results of flash separation experiments used to investigate the composition of crude oil in shallow and buried-hill reservoirs. Then, PVTsim Nova is used to simul

Abstract:

The generation of hydrogen from unconventional oil is expected to increase significantly during the next decade. It is commonly known that hydrogen is an environmentally friendly alternative fuel, and its production would partially cover the gap in energy market requirements. However, developing new cheap catalysts for its production from crude oil is still a challenging area in the field of petroleum and the petrochemical industry. This study presents a new approach to synthesizing and applying promising catalysts based on Ni, Co, and Ni-Co alloys that are supported by aluminum oxide Al2O3 in
