... may represent a lower bound for discontinuity radius, if the swept region is not cylindrical. Also, obtaining an accurate deviation time for small mobility contrasts may be difficult. Limitations on the deviation time method due to wellbore storage effects have been quantified indicating a need...

... $Gr bii~ii=Gi ~lo+< ~eme =n~ n~gr fiw with wellbore storage effect. In this respect a new relationship was developed for chec- king prccedure used in confirming the match point from log-log type curve matching and &p vs 4= plot for bilinear flow regime. Checking procedure forbilinear flow regime...
