... signal appears early (within 0.1 hr survey time) as boundary effect; thereby overlapping with wellbore storage effect phase and masking infinite acting radial flow period (used for estimating well and reservoir parameters). Hence, final build up was not proposed in such wells. Those parameters can...

... Abstract A new method for analyzing multi-rate well test data distorted by wellbore storage is presented. The approach affords a reasonable analysis in the Early-Time-Region (E.T.R) where analysis by the existing models is impossible due to afterproduction and skin effect. The technique...
