Abstract:

Results of calculated properties and rise behavior of methane-saturated crude oil droplets that are rising through 1,500 m of water column. Calculations have been done for Louisiana Sweet Crude (LSC) oil droplets which are initially liquid and fully saturated with methane.

Purpose:

The calculations have been done to investigate the size and rise velocity evolution of single methane-saturated Louisiana Sweet Crude (LSC) oil droplets throughout the water column while pressure decreases. Expansion of droplets and therefore increasing rise velocity is calculated and compared to crude oil droplets that are not gas-saturated.

Data Parameters and Units:

Rise height (m), Droplet volume growth ratio, Gas void fraction, Droplet diameter growth ratio (ratio of diameter to initial diameter), Initial diameter for velocity calculation (1 mm), Density (kg m-3), Rise velocity (m s-1), Droplet diameter (dp, mm), Rise time (t, hr), Rise velocity (up, m s-1), Morton number (Mo), Eötvös Number (Eo), Reynolds number (Re)

Methods:

Photographic image capturing with backlight illumination, evaluation of droplet sizes (equivalent diameter) with the software ImageJ.
