... of microbubbles in altering PVT properties will be quantified through a series of PVT data. It is expected that the PVT properties are significantly altered due to the presence of asphaltenes, with a complex dependence on the asphaltene concentration. Also important is the nature of the gas phase...

Due to the effects of fracturing treatments, such as fluid leak-off and fracture volume reduction upon closure, the polymer becomes concentrated on the formation face and within the proppant pack. At times the concentration of this polymeric filter cake becomes so high that...
