Gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. Experimental studies showed that an application of a combined technology of Gas Assisted Gravity Drainage (GAGD) and Vapor Extraction (VAPEX) could increase final oil recovery of a candidate viscous oil reservoir. In this paper the results of laboratory investigation are presented, including Pressure-Volu...

In this paper, the river network is divided into sub-networks forming a hierarchy of drainage systems following the Horton order. Then, drainage systems are rearranged based on their pattern to obtain more homogeneous drainage systems which do not necessarily follow the Horton order. Such reorganization facilitates the description of the network system. Such organization can be useful for terra...
