Establishing of pore fluids pressure is one of the critical challenges encountered in the formations opening in drilling. Pores fluids pressure evaluation through geophysical methods involves live recordings of the collector parameters using LWD (Logging While Drilling)/MWD (Measurements While Drilling) techniques. Empirical relationships of the dependence of pore pressure and the measured parameters use exponents whose values are accepted as constant. These exponents were determined on the basis of experimental d...
