... energy production. While the onset and propagation of viscous fingers during liquid-liquid displacement is considered to be of severe engineering consequences, little has been done to mathematically model the onset and propagation of a viscous finger. Viscous finger under double diffusive conditions...

...) runs on dark live oil at reservoir temperature to identify the onset of asphaltenes precipitation and bubblepoint during the same run. Black oil, a problem for visual and optical methods, is no barrier for this technology. Effects of inhibitors on solid-liquid equilibrium have been investigated...

... step towards applying any remedial options. There are various procedures applicable in determining the onset of wax and asphaltene precipitation conditions. These techniques are dependent on the oil characteristics. The most important criterion is the colour of the oil. For dark coloured oil...

... Abstract A heat transfer technique for the detection of the onset of asphaltene precipitation is presented and its versatility demonstrated. The technique is able to evaluate the effectiveness of asphaltene precipitation inhibitors, and solvents used to resuspend a deposit. It can also be used...
