| Abstract: | The problem of interpretation of geophysical data taking into account hydrodynamical and geo-mechanical processes in oil-drilling wells is considered. The effects emerging due to change of porosity and permeability are studied, and the influence of such effects on the geophysical measurements in a borehole is analyzed on the basis of characteristic parameters of the Kogalym oilfield reservoirs. |
