... Abstract Molecular diffusion plays a critical role in gas injection in tight reservoirs such as liquid-rich shale. Despite recent efforts on measuring diffusion coefficients at high pressures, there is a general lack of the diffusion coefficients in live oil systems at reservoir conditions...

... effects/live oil compositional changes on diffusivity is rare or not available in literature. The current work fills this gap and present the experimental observations on the effect of GOR on gas diffusivity in reservoir fluid systems. Synthetic live oils were created by combining stock tank oil (STO...

... to identify key mechanisms of asphaltene deposition in porous media and develop an asphaltene impairment model, this paper focuses on a systematic experimental study of asphaltene-related permeability damage due to live oil depressurization along the length of a flow system. An experiment was performed using...

... and reservoir temperature using dead crude oil from the reservoir of interest. There have been only a few experiments reported in the literature on live oil at reservoir pressure and temperature and the importance of those experimental results are conflicting. This paper investigates the effect of pressure...

... made to explain the dynamic behavior of IFT using a four-stage mechanistic model involving induction, diffusion, kinetic barrier and equilibrium stages. The significant difference observed between the advancing contact angles of live oil (55 °) and stocktank oil (154°) clearly indicates the need to use...

... are 560,000 cp (at 24°C) and 8.7, respectively. The solution-gas drive tests were conducted using live oils with GOR of 6.5, 9.0, and 12.2 (vol/vol at standard conditions). In two tests, initial water saturations of 4.0 and 5.2% were established. Five tests were conducted at a temperature of 35°C; one test...

.... The driving force for this study is an investigation of live oil transportation through a 600 km long sub-sea pipeline where ambient temperatures range from 0 to 5°C and pressures up to 3000 psia. The design and operation of such a system warrants unique set of input data. Measurement of such data involves...
