The influence of mineral oil content on the antitumor activity of emulsified Bacillus Calmette-Guérin cell walls (CW) was studied in mice each with an established transplant of a syngeneic fibrosarcoma. Animals received intratumoral injections of CW (0.02 to 0.6 mg/mouse) emulsified in 1 to 9% oil. The number of animals in which tumor regressed completely depended on the concentration of oil in...

Prediction of Surfactants’ Properties using Multiscale Molecular Modeling Tools: A Review — During one of the existing Enhanced Oil Recovery (EOR) procedures, a mixture of Alkaline/Surfactant/Polymer (ASP) is injected into wells in order to move the trapped oil from the reservoir to the wellbores. The conception and/or the tuning of new ASP combinations, structures of surfactants and/or mixture...

Lack of climate policy and CO2 markets along with a global economic slowdown suggest that we need to rethink our approach to demonstrating CCS at a commercial scale. Austerity measures make it likely that public funding will be tight in coming years, and there is a striking need to ensure that limited funds are spent optimally. Quantitative tools exist for aiding decision making under uncertain...

Future exploitation scheme of an oil reservoir in each cycle within its production life depends on the profitability of the current extraction scenario compared with predicted recoveries that acquire with applying other available methods. In fractured reservoirs appropriate time to pass from the gas injection process into chemical enhanced oil recovery (EOR) firmly depends on the oil extraction...

a new chemical compound is developed at petroleum university of technology to enhance therecovery of the free imbibition process and simultaneously hinder asphaltene precipitation. thecompound is tested on heavy oil samples from marun oil field, bangestan reservoir. the effects ofthe chemical compound on viscosity, hydrocarbon composition, and average molecular weight ofthe heavy oil are invest...

Abstract In recent years, silica-based polymer nanofluids (NFs) have attracted more and attention because they can enhance temperature salt tolerance. This study summarized the research progress prospects of NFs in enhanced oil recovery (EOR). First, synthesis method effect on were studied. Research rheology, wettability, viscoelasticity, interfacial tension, adsorption, porous media flow, emul...
