... mathematically into a new solution of diffusivity equation. Type curves for various combinations of related parameters are generated to develop an insight into pressure transient behavior. The practical utility of the new model is demonstrated through application to the actual field data. storage model...

... presents type curves are more gently and less than that obtains from the method of start-up pressure gradient. Also, this non-linear effect measure makes derivative of pressure curve less and more early time than that gets from the closed boundary effect and there are be obviously distinction. This study...

... 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...

... will be probably formed around a well. It is one of the important reservoir engineering problems to determine the range of the zone and the degree of permeability variation. A transient well test interpretation model (composite sandstone reservoir mode D together with the new type curves are presented...

... ABSTRACT Use of type curves based on the dimensionless pressure and its logarithmic derivative has become a standard method for analyzing well tests data. Recently, a new procedure for constructing type curves using a dimensionless pressure group which involves the ratio of the dimensionless...

... ABSTRACT Numerous type-curves of dimensionless pressure versus dimensionless time have been developed in the past. They all suffer from the fact that the log-log representation has poor resolution at late time, thus the uniqueness of the match is reduced. The semi-log representation enhances...
