Petrophysical model of ultrasonic logging (by T) for the sand-silt rocks of the Bilche-Volitsa zone of Subcarpatian trough

The creation of propagation time petrophysical model for different boreholes and geological conditions of sand-silt rocks occurrence is shown on an example of Neogene's sediments of External zone of Subcarpatian trough. The multidimensional statistical model is constructed only on the base of well-logging data. This model allows to take into account an effective pressure in the rocks and the contents of clay material in the rock-reservoirs for the definition of porosity by the ultrasonic logging data.
