The analytical pressure solution is derived by making an extensive use of the residue theorem.
In this paper we present semi analytical pressure transient solutions for a limited-thickness open cylindrical production ring (often called limited entry or partially penetrated) on a non-permeable cylindrical wellbore in a porous medium which is used for fluid withdrawal (production) from the formation.
The volume of injected mercury (SHg) at each pressure increment is automatically recorded until the maximum analytical pressure, or 100%% pore-volume mercury saturation is achieved.
The pressure response at the wellbore was compared against analytical pressure transient solution introduced by Warren and Root (1963) for dual-porosity model.
The numerical model is validated against an analytical pressure transient solution for dual-porosity system, and then applied to a real case taken from fractured basement reservoir in offshore Southern Vietnam.
