Paper presented at the International Oil and Gas Conference and Exhibition in China, June 8–10, 2010
Paper Number: SPE-130977-MS
... Abstract This paper presents a new model for analysis of changing wellbore storage during pressure transient testing. The model accounts for the combination of instantaneous change of wellbore storage with wellbore phase redistribution effects. Both wellbore effects are incorporated...

Paper Number: SPE-50905-MS
... Abstract Conventional type curve fitting analysis of early-time transient pressure data influenced by wellbore storage effects can yield non-unique results due to similarity in the shape of the curves. In order to alleviate this problem, this paper proposed an optimum method based on adaptive...

... to the conventional approach. In the study, we present a pressure-transient radial relaxation flow model of non-Newtonian visco-elastic fluids in fractal reservoir considering the effect of wellbore storage and skin factor. Analytical solution and asymptotic solution in real space are obtained by using Laplace...

... of conservation mass. The solution for the new model was obtained in real space. The type curves for the vertically fractured well in both homogeneous and dual-porosity reservoirs with and without wellbore storage and skin effect were calculated. In order to consider the wellbore storage and skin effect...

... of this is that the matching procedure requires the movement of the field data only in the horizontal direction. This improvement not only facilitates the type curves match but also increases the reliability of the analysis results. New type curves are presented for wells in radial systems with wellbore storage and skin...

Pulse test responses in multilayer heterogeneous reservoirs are investigated for unequal layer pressures, vertical layer heterogeneities, and wellbore storage effects both at the active and observation...
