The Effects Of Hydro Confining Pressure On The Flow Properties Of Sandstone And Carbonate Rocks

There is a significant effect of the hydro confining pressure of the core holder on the flowing properties of the formation rocks. This effect is caused due to the mechanical elastic deformation of the core when carrying out laboratory studies of the waterproof and polymer compositions. Consequently, this deformation will cause changing in the permeability and voids storage capacity of the studied core samples. Therefore, under the laboratory conditions and when dealing with such studies on formation cores, it is necessary to consider the changes of permeability and voids storage capacity of these cores.
