Petrophysical model of residual water saturation of the terrigenous rocks in the region of the reservoir – non-reservoir transition

Authors: A.V. Malshakov (Tyumen Branch of SurgutNIPIneft)
The residual water saturation factor of terrigenous rocks in the region of the reservoir – non-reservoir transition is considered within the framework of bidisperse percolation model. The scaling function allowing uniformly to describe the relationship between the residual water saturation and the volume content of granulometric fractions and between filtration-capacitive properties of terrigenous rocks is obtained with  use of self-similar transformation of variables. The obtained results are compared with empirical data.
