... Abstract This study aims to compare the roles of rock and crude oil in improving recovery by low salinity water injection (LSWI) and, particularly, to explore the significance of micro-dispersion formation in LSWI performance. Core samples and crude oil were taken from two carbonate reservoirs...

... Crude oil from Yanchang formation (Nanniwan Oilfield) with the viscosity of 4.34mPa·s and density of 0.84g/cm 3 was used. Core samples used in coreflooding experiments were obtained from the outcrops of Yanchang formation and their petrophysical properties are shown in Table 1 . Table 1...

This study investigates the cost competitiveness of an alternative strategy to market crude oil priced to cover the cost of removing an amount of carbon dioxide equal to that produced through combustion of transportation fuels to be refined from it. This strategy enables continued use of fossil...

..., which consequently stabilized the CO 2 foam especially in the presence of crude oil. NCF-st-CO 2 foam presented dense bubbles and a thick framework as observed visually from the cell. The flow behaviors of CO 2 foam in fractures were largely determined by the bulk foam stability. NCF-st-CO 2 foam...

... does not always increment oil recovery. It is a specific combination of properties of an asphaltenic crude oil, chemically equilibrated brine, and rock surface that may explain the success or failure of LSW. In this work, we introduce a novel experimental approach to study asphaltene-like chemical...

... are; ethane, propane and n-butane. At sufficiently high pressures, natural gas, flue gas, liquefied petroleum gas and carbon dioxide can develop multi-contact miscibility with crude oil. The pressure essential to develop miscibility is dependent on the oil composition and the reservoir temperature...

...Chemicals Deionized water was obtained from a Milli-Q water system (Synergy, EMD Millipore Corporation), giving resistivity greater than 18.2 MPΩ.cm at 25°. Toluene (99.9%, Fisher Chemicals) was used as received to dilute the crude oil. In all of our studies, we used 3 wt% crude oil in toluene...

Together with polar components from the crude oil, they can organize into a highly viscous network and stabilize water droplets in the oleic phase. Oil-soluble alcohol...

... Methanol (99.9%, VWR), MEG (100%, Alliance Chemical), n-pentane (98%, Alfa Aesar) and Xylenes (≥98.5%, Fisher Scientific) were used as received. Crude oil and wax samples were generously provided by four independent operators in US. General information about these samples are given in Tables 1...
