Additionally, the fabric of the Montney formation contains clays, which displays osmotic membrane characteristics in the presence of high salinity gradients...

... years and proved to be effective in experiment study. N2, C1, CO2 or other rich gases are used in shale oil EOR. The purpose of this paper is to compare the EOR potential of different gas and provide a guide to choose gas based on the Wolfcamp shale oil reservoir. The composition of crude oil from...

... displacing crude oil. Initially crude oil itself was suggested as base oil for generating this type of emulsion, and both laboratory experiments and field pilot have demonstrated its high efficiency in recovering heavy crude. Recently used engine oil was suggested as a candidate for generating W/O emulsions...

... for these data is laboratory tests. This paper presents experimental study of some PVT properties of Athabasca crude oil to help provide input data for further numerical studies. Viscosity of Athabasca heavy crude was measured using a rotational viscometer up to 300 °C. This viscosity data is a more reliable...

... Abstract As populations and economies continue to grow globally, energy demand will grow proportionally. Extensive work by Peter Tertzakian ( 2006 , 2009 ) has shown crude oil supplies may not keep pace with this increased demand. The shortfall must be met by other energy sources. Only two...
