The impact of three actual crude oil compositions with different GORs and CO2 contents is evaluated. The optimal operating pressure settings of CCS greatly minimize...

... should be utilized. As each mass is divided by its molar mass, inaccuracies of the SCN MW distribution used for each fluid can heavily affect the reported molar composition which is the one used in the PVT & Reservoir Engineering calculations. Until today, PVT labs use the Katz & Firoozabadi...

..., 1978 , Coats 1980 ). Most commercial laboratory PVT reports, pre-1980, provided compositional analysis with a single heptanes-plus "residue". It was shown ( Yarborough 1978 , Coats 1980 , Schulte 1980 , Brulé et al. 1985 , Zick 1986 ) that complex fluid phase behavior such as miscibility...

... previous correlations have been established to estimate the MMP, however, a few did not consider the composition of oil. The correlations by Lee et. al.(1979)( Lee 1979 ) and Yellig & Metcalfe (1980) ( Yellig and Metcalfe 1980 ) only accounted for the temperature of the reservoir as input ( Lee 1979...

... Abstract Flash calculation is an essential step in compositional reservoir simulation. However, it consumes a significant part of the simulation process, leading to long runtimes that may jeopardize on-time decisions. This is especially obvious in large reservoirs with many wells...

..., including improving combustion front propagation and shale oil recovery. Copper (II) stearate (0.1 wt% by metal) was used as an oil-soluble catalyst to improve the process of ISC. The performance of ISC was evaluated in terms of material balance, recovery factor, composition of evolved gases, and produced...
