Removing mud residues/deposits behind sand screens

Challenge Overview
Well OperationsProduction TechnologyOil
Description

We have a well with a minimum ID of 2.650". The well is completed with sand screens with pre-drilled base pipe. We suspect that poor mud quality from drilling phase might have introduced debris behind the screens which is affecting production. 4" screens.

 

The production from the well is much lower than expected. Debris behind screens is main theory, but has not been confirmed. Looking for Intervention solution to remove the suspected debris.
