Paper Number: SPE-36518-PA
Published: 01 December 1997
.... Therefore, the properties defined on a smaller scale are upscaled to a coarser scale. Few prior studies on permeability upscaling paid special attention to the problem of radial flow in the vicinity of a wellbore. This study presents an analytical method to calculate effective permeability of a coarse-grid...

...Jetzabeth Ramírez-S.; Fernando Samaniego-V.; Fernando Rodríguez; Jesus Rivera-R. Summary This paper presents a solution for the inverse problem, or interpretation, of the radial flow of tracers in naturally fractured reservoirs. Our model considers cubic-matrix-block fracture geometry, and by using...

... type-curve matching, identifies the flow regimes effectively, and gives greater confidence in the results. A new method to correct the pressure buildup when drawdown type curves are used in radial-flow wells is also proposed. Two example applications, one with a long producing time and one with a short...

... condition in some detail. By considering the flux distribution along the perforated interval in a partially penetrated well after radial flow is established, they were able to define an "equivalent average pressure point." This represents the location in the vertical direction at which, after radial flow...
