ABSTRACT

A number of techniques have been developed for the analysis of slug tests performed in the presence of well skins. The method of H. J. Ramey et al. is the most common approach for incorporating the effects of a well skin into the analysis of slug tests performed in fully penetrating wells. The deconvolution method is based on transforming response data from a slug test into the equivalent drawdown that would have been produced by a constant rate of pumping at the same well in the absence of wellbore storage effects. The same issues of practical importance with respect to the Ramey et al. method for fully penetrating wells are also of significance for tests performed in partially penetrating wells. The techniques commonly used for the analysis of slug tests performed as part of shallow groundwater investigations estimate the hydraulic conductivity of the formation using various normalized plots of the response data.
