Abstract
Disclosed herein are methods for preparing a wellbore for production or injection. The methods may include the steps of positioning a completion longer than 300m comprising an inflow control device (ICD) having radial flow paths in the wellbore adjacent to a filtercake and determining the pressure required to lift the filtercake off of the wellbore. The radial flow paths of the ICD are designed such that when the filtercake adjacent to a downstream portion of the ICD completion is removed, the pressure drop across the first downstream part of the ICD completion is sufficient to maintain a drawdown pressure high enough such that the second upstream filtercake is also removed.
