... a pseudopressure transform for determination of formation permeability during transient radial production from a gas reservoir. The nonlinearities associated with viscosity and isothermal compressibility of gas during the boundary-dominated flow regime were addressed by introduction of a pseudotime transform...

... However, the term μ g c t on the right side of Equation (3) is still a function of pressure (and as a result a function of pseudopressure), which means this partial differential equation is still nonlinear. One may define a pseudotime transformation as (4) t a = ( μ g c...

... pseudopressure and total material balance time functions are defined. Subsequently, the methodology for calculation of these functions is presented. This is followed by the presentation of data analysis procedures which are based on introduced BDFEs. Finally, a verification and discussion section is presented...

... and flow differential terms. A version of the Kirchhoff transformation is used to make the accumulation term linear, while a monotonically varying nonlinearity (as a function of a new pseudopressure function introduced in this work) exists in the flow differential term. The transformation, however, does...
