Additionally, there is a tendency for higher molecular weight gases to remain in solution when OBM drilling mud are used. This gives rise to high gas muds being...

... reconstituted to different live oil compositions targeted on the reservoir composition from which the base oils were sampled. Because there is little optical activity of methane, ethane, and propane relative to that of carbon dioxide in the 2500 to 3300 nm region, only methane was added as the dominant...

..., the literature that considers the correlations of T1, T2, D and for live oils is sparse. Studies of several n-alkanes enlivened by methane are the basis for most analysis. Recently there have been claims that the corre- lations do not apply robustly to live crude oils. This pa- per reviews several studies made...
