Abstract

Summary A mathematical model for pulse testing is presented that examines the influence of wellbore storage and skin effects on pulse-test data. Two new correlations are provided for correcting the storage-dominated response amplitude and time lag to within 3% of the values expected without wellbore storage. The formation transmissivity and storativity can be determined from the corrected response amplitude and time lag. Proposed correlations are applicable to pulse testing with wellbore storage at the active or observation well. Examples illustrate use of the new correction technique.
