Carbonate reservoirs are a highly heterogeneous type of reservoir characterized by the presence large amount vugs and pores. During two-phase displacement, flow regime in might be gravity segregated. The distribution pattern fluid would accelerate water downward horizontal directions, meanwhile decelerating an upward direction, resulting different oil recovery ratio. This gives rise to question...

Computations of the relative permeability curves were made through their representation by two functions for wetting and nonwetting phases. Each function contains one parameter that controls shape curves. The values these parameters are chosen to minimize an objective function, is represented as a weighted sum squared differences between experimentally measured data corresponding calculated mat...

The nitric oxide (NO) cascade and endothelial NO synthase (eNOS) are best known for their role in endothelium-mediated relaxation of vascular smooth muscle. Activation of eNOS by certain inflammatory stimuli and enhanced NO release have also been shown to promote increased microvascular permeability. However, it is not entirely clear why activation of eNOS by certain vasodilatory agents, like a...

Capillary pressure and relative permeability are important parameters in geothermal reservoir engineering. It is essential to represent capillary pressure curves mathematically in an appropriate way. The Brooks-Corey capillary pressure model has been accepted widely, however it has been found that the Brooks-Corey model cannot represent capillary pressure curves of The Geysers rock samples. In ...
