ABSTRACT
All of the analysis methods discussed in the previous chapters have been based on the assumption that the formation is homogeneous, i.e., the hydraulic conductivity of the material immediately adjacent to the test interval is the same as the bulk average conductivity of the formation. However, as emphasized in Chapter 2, the process of drilling, installing, and developing a well will often result in the material in the immediate vicinity of the well having different characteristics than the for mation as a whole. This zone of altered characteristics, the well skin, may have a considerable impact on the hydraulic conductivity estimate obtained from a slug test. A number of techniques have been developed for the analysis of response data from slug tests performed in the presence of well skins. The most common of these techniques are described in this chapter.
