Phase behaviour of petroleum

John Alpheus Putnam obtained from University of California, Berkeley CA, the BS degree in 1930, the MS degree in 1934, and the PhD degree in 1943, all in mechanical engineering. He worked after his MS degree as research engineer at Kettleman Hills CA for the Standard Oil Company until 1939, applying in the volumetric and phase behaviour of petroleum hydrocarbons to reservoir analysis. This work on the phase behaviour combined with the fundamentals of flow in porous media was destined to become his major professional interest.

The saturation pressures (bubble and dew points) of petroleum liquid and vapour phases are closely related to the GOR of the liquid and the CGR of the vapour and strongly influence the production behaviour of these phases. Yet geologists and petroleum engineers have often assumed very simple values for these saturation pressures, for example ... 

The two extremes, using instantaneous and cumulative phase predictions discussed above, provide only the framework for the total variability, which can be expected in the reservoir filling history studied here. Unravelling the evolution of petroleum fluid compositions in the Snorre Field through time would require a model resolution far exceeding what can be handled in reasonable computing time. The approach shown allows, however, a prediction of fluid properties, which is much closer to the natural fluid compositions than previously possible. This compositional kinetic scheme is the first of its kind to allow reasonable petroleum phase behaviour assessment in the simulation of basin evolution and hydrocarbon migration.

The naturally biodegradable polymers such as starch, chitosan and cellulose derived from natural sources have produced a number of interesting NR blends and IPNs. These blended systems have an advantage in that they create fewer waste disposal problems compared to the petroleum based polymeric materials. The use of stareh blends to enhance the biodegradability of conventional plastics has been reported by many researchers in order to reduce the environmental impaet of petroleum based plastic products and waste. The NR/maize stareh blends exhibited a decrease in their mechanical strength due to the speeifie properties of starch. However, the blended polymers showed a low interfaeial interaetion between the two phases due to the different polarity behaviour of the hydrophobic NR and the hydrophilic starch.
