Abstract

A completion method isolates a lower zone while circulation at high rates takes place above to clean debris out of the wellbore. Pressure fluctuation sensitive equipment in a lower completion is isolated with a tubing valve during circulation. This further prevents debris from clogging inlet pressure passages to equipment below the isolation valve during circulation to get the debris out. After circulation the packer is unset and the tubing valve is opened and a wellbore filter tool directs well fluids through a screen and captures the debris as the string is pulled toward the surface.
