... dividing on free and residual water shares. On the base of petrophysical model of effective porosity we establish a new way of Gassmann's relation application for fluid effect on elastic properties simulation. This fluid substitution model takes into account free and residual water volumes and properties...

... ] converted α wc =f(m) correlation into two versions of relationship between effective porosity and porosity m. Later on this proposal [ 2 ] was included into recommended practice [ 3 ] approved by the State Reserves Committee Rosnedra (SRC) specifying to use petrophysical correlation of effective porosity me...

... helped to decrease the water production rate and increased slightly the oil production rate. The associated economic evaluations were based on simulated forecasts while connected volume calculation was made for the chosen realization. reservoir simulation assumption effective porosity identify...

... ) is a hyperbolic dependence which is operated by three independent parameters {μ 0 , Δμ φ Μ }. These paremeteres are characteristic parameters of the reservoir. The content of bulk residual water (or product S wr φ t ) linearly depends on effective porosity ( fig. 1b ): (5) S w r φ t...

... of oil and gas reservoirs. But for the complex reservoirs porosity has appeared to be a misinformation parameter: the reservoir rock with high porosity may fail to possess effective porosity that is it may not be a reservoir. It is necessary to consider a corresponding petrophysical model...
