The experiments were carried out on columns of 3 core samples 5 cm length and 3 cm in diameter. The course of the experiment included...

... that the amount of energy required by the process correlates with water saturation in the near wellbore region, higher water saturation levels are preferred for enhanced oil recovery. It is also noticed that majority of the electromagnetically induced heat rate is generated in the near wellbore region vaporizing...

... Abstract The article presents a new method of determining the residual water saturation of the Bazhenov Rock Formation using synchronous thermal analysis which is combined with gas IR and MS spectroscopy. The efficiency of the extraction-distillation method of determining open porous...

... in the reservoir and has the characteristics of "defoam when meeting oil and stabilizing when meeting water". It has high percolating resistance in the part with high water saturation, which forces to inject the crude oil in the unaffected or weakly swept area during fluids driving so as to expand the swept volume...

... aimed to improve the accuracy of the geological reservoirs model by reducing uncertainties related to fluid contacts (OWC, GWC), water saturation (Sw), and reservoir properties by building geological models that satisfy seismic and electrical survey data. Building an integrated geological model...

... on the connate water saturation. After that the calculation of water cut values using the synthetic relative permeability Corey-functions with constant phase permeability end points, was performed. Then the results were compared with MDT tests ( Khabarov, 2010 ); it was shown that estimated water cut values were...
