Paper Number: SPE-170076-PA
Published: 03 November 2015
..., oil production could be impeded by steam breakthrough at one location of the producer and higher liquid level above the other sections of the producer. Various completion methods have been proposed to improve production efficiency. Outflow-control devices (OCDs), such as steam splitters, are used...

... modifications on sur- face facilities should be completed. This is not necessarily the time at which breakthrough of CO2 will occur. However, there is a ten- dency to implement such modifications earlier to allow for the un- certainties inherent in simulation models. Thus, the more accurate the simulation model...

In this study, waterfloods were performed at multiple rates in cores containing heavy oil and connate water. In some cores, oil was initially free...

..., it was observed that there was a delay in CO 2 breakthrough, associated with a period when only a mixture of methane and nitrogen was produced. This is so because solubility of CO 2 in connate water is considerably higher than that of nitrogen. This leads directly to a higher gas recovery due to a longer...

In addition, heterogeneous properties of the porous media always cause a bypass flow resulting in early water breakthrough and poor water...
