Paper Number: SPE-70035-MS
... such as permeability, wellbore storage coefficient, and skin factor. Finally, field examples of pressure falloff analysis are presented to illustrate use the direct synthesis and results are compared with those from type curves and conventional semilog analysis. Introduction Traditionally water flood schemes have...

... to acid treatments. Skin factor was calculated explicitly in the method from pressure and flow rate, which can be directly measured during a treatment. Skin factor is then used to identify the well response to acid injection, and therefore to understand and control the stimulation process. There have been...

... Abstract The use of an inverse injectivity versus superposition time plot to diagnose the changing skin factor in a matrix acidizing treatment has been presented previously by Hill and Zhu 1 . The model has been extended to calculate skin factor as a function of injection time or injected...

... the final straight-line region is present. The primary emphasis of most of this work was to quantify the apparent damage caused by the near-wellbore restriction to flow due to partial perforation. Saidikowski showed that the total or apparent skin factor, s, based on Horner analysis of the final straight...

... reservoirs, the slope and intercept of the decline curve plot are used to estimate reservoir pore volume. However, estimates of skin factor and permeability are required to calculate the reservoir shape factor from either the slope or intercept of the decline curve plot. For naturally-fractured reservoirs...
