The article presents a volumetric production analysis at the wellbore-sand face contact. It identifies wellbore storage effects to significantly smear the accuracy of evaluating reservoir productivity through the fluid outflow rate from the annulus during underbalanced drilling. It mentions that with the existence of underbalanced pressure conditions at the bottomhole, the modeling procedures presented in the study could be used for predicting the total volume of gas inflow with significantly reduced wellbore effects while drilling. |
