material balance calculations for petroleum reservoirs
In petrophysics, Archie's law relates the in-situ electrical conductivity of a sedimentary rock to its porosity and brine saturation: ϕ {\displaystyle \phi \,\!} is the tortuosity factor. for the brine resistivity. is also called the resistivity index . It is a purely empirical law attempting to … Gas formation volume factor. - KOYAPETE Gas formation volume factor. The gas formation volume factor is used to relate the volume of gas, as measured at reservoir conditions, to the volume of the gas as measured at standard conditions, i.e., 60°F and 14.7 psia. This gas property is then defined as the actual volume occupied by a certain amount of gas at a specified Gas formation volume factor, [rcf/scf] Bg - Gas formation volume factor, [rcf/scf] Function Description; 1 BwMcCain: McCain correlation for water formation volume factor, [bbl/STB] Oil Correlations - fekete.com

Waxman and Smits explained the physical significance of the quantity X in terms of the composite term BQv/F*, where Qv is the cation exchange capacity per unit pore volume, B is the equivalent conductance of sodium clay exchange cations (expressed as a function of CW at 25 degrees C) and F* is the intrinsic formation factor for a shaly sand. A proposed solution to the determination of water ... Mar 13, 2018 · The first terms of the Simandoux equations do not show a volumetric balance between the sandstone volume and the clay volumes, and the lack of a shale formation factor in the clay term makes the correction for clay effect by the Simandoux equation too large and hence reduces the amount of water saturation calculated. New Correlations For Formation Volume Factors Of Oil And ...
1-2: Above the bubble point pressure, the oil formation volume factor and two phase oil formation volume factor are equivalent. This is because no free gas exists in the reservoir. Mathematically this can also be shown because at pressures above the bubble point the solution gas oil ratio is constant, therfore . Thus Equation 1 reduces to .
