          which it is important to respect the standards and perform
        
        
          verifications. The large scale is that of pumping tests, which
        
        
          must be interpreted for steady-state.
        
        
          The results presented here have shown that, when
        
        
          stratification is adequately considered, slug tests are interpreted
        
        
          according to standards, and the resulting
        
        
          
            K
          
        
        
          distributions are
        
        
          taken into account, the conclusion is that there is no scale effect.
        
        
          Therefore, using a quality control approach for analyzing the
        
        
          GSDCs and interpreting field test data is essential for cross-
        
        
          checks, and for avoiding the creation of artificial scale effects.
