Abstract In this study, an equation of state has been modified for calculation of phase behavior of fluids and PVT properties of gas condensate. The accuracy of the modified EOS has been proved by estimation of the properties of some hydrocarbons...

... methods to estimate reservoir permeability and its variation along the wellbore using the inflow measurements at the wellhead. The traditional methods of pressure and rate transient analysis are not applicable to underbalanced drilling data particularly because the length of the producing interval...

... Abstract This paper presents a procedure to estimate relative permeability curves together with gridblock porosities and permeabilities by automatic history matching three-phase flow production data using the LBFGS algorithm for optimization and the adjoint method for generating sensitivity...

... Abstract New graphical techniques are presented for estimating the diffusivity coefficient (or mass diffusivity) of light gases in highly-viscous bitumens from pressure-decay data. These methods are based on modeling the rate of change in pressureusing the diffusion equation coupled...
